Alias answer
1/16 x 1/32 in
The phrase 1 16 x 1 32 n52 magnets is answered here as a micro N52 block format, not a separate URL.
Metric size
1.5875 x 1.5875 x 0.7938 mm
Exact conversion uses 25.4 mm per inch before tolerance, coating, and edge-chip allowances.
N52 class
49-53 MGOe
Public N52 sheets list high room-temperature energy product; final assembly force still depends on geometry, magnetic circuit, and test method.
Thermal screen
60 C review
Arnold catalog data lists standard N52 with a 60 C maximum working-temperature marker; hotter duty needs high-coercivity review.
Weight screen
about 0.015 g
Using 7.6 g/cm3 density, the alias block is roughly 15 mg before coating and lot variation.
Main boundary
Micro handling
This size needs controlled trays, polarity workflow, safety review, and inspection because pull area and part mass are tiny.
Stage1b research update
The audit found that the first version answered the alias and provided a useful calculator, but several decision-impacting claims needed tighter evidence: pull-force certainty, thermal suitability, consumer-safety scope, air-shipment thresholds, and supply-chain exposure.
Evidence remains incomplete for exact finished-part pull, flux-index compliance, coating stack-up, and shipping carton status. Those items are now marked as sample, lab, supplier, or package-specific instead of being inferred from the N52 label.
| Gap found | Evidence added | Decision impact |
|---|---|---|
| Pull estimates looked more precise than the evidence allows | Arnold states material data and demagnetization curves are typical and vary with shape and size; IEC frames standards around material properties and tolerances, not finished pull force. | The page now labels pull as screening only and requires sample pull or magnetic moment testing before purchase release. |
| Temperature was mentioned but not converted into a decision gate | Arnold public grade table lists standard N52 with a 60 C maximum temperature marker, while higher-coercivity families trade peak energy for heat margin. | The RFQ checklist now treats sustained heat above room temperature as a supplier review item rather than a default N52 purchase. |
| Safety guidance did not separate industrial and consumer scope | CPSC guidance applies Part 1262 to subject magnet products for entertainment, jewelry, mental stimulation, stress relief, or combinations, with exclusions for solely industrial or professional channels. | Consumer-accessible use is now a separate risk boundary, while industrial-only use still requires channel and retention documentation. |
| Bulk packing and air shipment were under-specified | FAA PackSafe uses a package or magnet field threshold of 0.00525 gauss at 4.5 m / 15 ft from any surface. | The page now asks for package-level field checks, keepers, spacing, and shielding review instead of relying on single-magnet size. |
| Procurement risk was generic | IEA 2026 reporting shows highly concentrated 2024 refining and magnet manufacturing; USGS 2026 reports 2025 U.S. rare-earth import reliance and stockpile interest in NdFeB magnet block. | The sourcing advice now includes lot traceability, alternate grade comparison, lead-time exposure, and supplier qualification. |
Treat 1 16 x 1 32 n52 magnets as an RFQ shorthand that needs normalization, not as a complete specification. The tool produces a controlled screening result, while the report explains why the final decision depends on drawing, magnetic circuit, handling, compliance, and sample validation.

The missing face dimension is the key ambiguity. The page default assumes a square-face micro block, but the purchase order should carry a drawing or a complete three-axis description.
The quick check combines exact inch conversion, geometric volume, 7.6 g/cm3 density screening, and a conservative contact-condition pull screen. It is deliberately not a certified magnetic model: N52 material data, target steel, field leakage, gap, temperature, coating, and shear direction all require supplier validation.

Use this table to decide whether the calculator result is enough for a sourcing conversation or whether the next step must be a drawing review, sample test, safety review, or package-level measurement.
| Decision | Reliable when | Not reliable when | Minimum proof |
|---|---|---|---|
| Use the default alias size | The missing face dimension is intentionally treated as 1/16 in, making a 1/16 x 1/16 x 1/32 in block. | The buyer actually means a strip, disc, ring, or a two-dimensional shorthand from a legacy catalog. | Drawing with all three dimensions, tolerance, and magnetization axis. |
| Trust the weight estimate | Only a screening mass is needed and 7.6 g/cm3 is acceptable for sintered NdFeB density planning. | The purchase needs shipping weight, coating mass, adhesive mass, or lot-specific density. | Supplier inspection data and packed sample weight. |
| Trust the pull estimate | The number is used only to compare scenarios inside this tool under the same contact assumptions. | The value is used as a guaranteed axial pull, shear load, flux index, or safety certification. | Fixture pull test on real target steel, gap, coating, and direction. |
| Use standard N52 | The assembly is compact, dry, room-temperature, and envelope-limited. | Sustained heat, thin geometry, demagnetizing fields, impact, or corrosive exposure is unresolved. | Supplier demagnetization review, grade family comparison, and sample aging test. |
| Ship by air | The packed carton has been measured below the FAA 0.00525 gauss boundary at 4.5 m / 15 ft. | Bulk magnets are packed without keepers, spacing, shielding, or a package-level field check. | Package magnetic-field measurement and carrier dangerous-goods review. |
| Field | Recommended | Why it matters |
|---|---|---|
| Canonical route | /learn/n52-magnet | The alias 1 16 x 1 32 n52 magnets shares the N52 magnet intent cluster and should not split authority into a duplicate page. |
| Size notation | 1/16 in x 1/16 in x 1/32 in, or metric drawing | The searched phrase omits one face dimension. Quote requests should state all three dimensions and tolerance. |
| Grade | N52 with supplier data sheet and lot traceability | The grade name should map to Br, Hcb, Hcj, and BHmax ranges. It should not replace finished-part validation. |
| Magnetization | State through-thickness, length, width, or custom axis | A micro part can become unusable if polarity direction is assumed instead of controlled by drawing and fixture. |
| Coating | Ni-Cu-Ni for indoor screening; epoxy or custom review for exposure | Coating thickness is material at sub-2 mm scale and can affect fit, corrosion resistance, and chip acceptance. |
| Validation | Sample pull, surface flux or moment, dimensional Cpk, and tray handling | Micro N52 magnets fail in procurement when only catalog force is specified and assembly handling is ignored. |
N52 is valuable when the envelope is fixed and room-temperature magnetic energy is the limiting factor. It is a weaker decision lever when heat, gap, target steel, coating, or handling drive failure risk.
N52 can be the right choice for a tiny fixed pocket, but it is not the only lever. These tradeoffs convert the research into RFQ instructions that a buyer can verify.
Upside: Maximizes room-temperature energy density inside a fixed micro envelope.
Cost: Can add price and supply sensitivity without improving performance if gap, steel, or heat dominates.
Rule: Quote N42/N45/N52 in parallel unless the envelope is locked and sample tests prove N52 is needed.
Upside: Improves thermal and demagnetization margin for hot or thin geometries.
Cost: Usually sacrifices peak energy product or adds cost, so it is not a free upgrade.
Rule: Ask for M/H/SH/UH family review when sustained temperature or irreversible loss is credible.
Upside: Can improve corrosion resistance when the environment is humid or chemically exposed.
Cost: At 0.79375 mm thickness, coating stack-up can consume meaningful clearance and change fit.
Rule: Freeze post-coating dimensions and corrosion test method before production tooling.
Upside: May avoid consumer product scope when distribution is controlled and documented.
Cost: Does not remove ingestion, pinch, electronics, or transport hazards if parts become accessible.
Rule: Document end use, retention, packaging, labeling, and reseller restrictions in the RFQ.
Upside: Simplifies purchasing and may reduce piece price for pilot demand.
Cost: Raises grade-verification, export-control, and lead-time exposure in a concentrated supply chain.
Rule: Require COA, lot traceability, incoming test plan, and alternate approved source before ramp.
The canonical N52 magnet page should answer both broad grade intent and the 1/16 x 1/32 alias. This comparison keeps the decision tied to application fit instead of repeating grade claims.
Best for: Tiny sensors, coding magnets, compact closures, miniature fixtures
Tradeoff: Highest room-temperature grade class, but handling, polarity, coating, and safety review dominate.
Best for: Cost-sensitive assemblies where envelope can grow slightly
Tradeoff: Lower energy product but often easier to balance cost, heat margin, and yield.
Best for: Axial pull against flat steel or circular pocket designs
Tradeoff: Different flux path, tooling, and retention geometry than a 1/16 x 1/32 block.
Best for: Holding force when part envelope can include a flux return path
Tradeoff: More components, changed corrosion design, and different inspection criteria.
Best for: Low-cost, lower-risk, or molded feature applications
Tradeoff: Much lower energy density, so not a drop-in substitute for a micro N52 size.
These internal paths keep the alias connected to adjacent buyer decisions without creating a duplicate 1/16 x 1/32 N52 magnet route.
Use when the drawing moves from a micro block to an axial-pull disc or cylinder.
Compare a slightly lower grade when heat margin, availability, or cost matters more than peak N52 energy.
Check cube-specific normalization, weight, handling, and RFQ language for tiny square magnets.
Move from alias research to block, bar, coating, tolerance, and magnetization production options.
Use when the missing dimension, coating, pull test, or package field check needs engineering review.
A micro N52 magnet can fail because of ambiguous dimensions, handling, safety, or shipping constraints even when the material grade is correct.
Impact: 1 16 x 1 32 n52 magnets states two dimensions, so buyers and suppliers may infer different block, strip, or disc formats.
Mitigation: Use this page as canonical intent coverage, then require a three-dimensional drawing before quote release.
Impact: N52 does not overcome air gap, target steel saturation, shear load, heat, or poor retention.
Mitigation: Validate in the real magnetic circuit and compare lower grades if geometry or target steel is the bottleneck.
Impact: Sub-2 mm magnets can flip, bridge, chip, or disappear during manual handling and adhesive placement.
Mitigation: Use trays, polarity marking workflow, counting controls, and fixture-based assembly before pilot production.
Impact: Loose high-powered magnets can create ingestion, pinch, electronics, and packaging hazards.
Mitigation: Run product-safety review for consumer access, document industrial-only channels, and avoid loose spare magnets.
Impact: A few microns of coating can be meaningful against a 0.7938 mm thickness and can change fit or edge-chip criteria.
Mitigation: Put post-coating dimensions, coating type, visual acceptance, and corrosion test requirements on the drawing.
Impact: A single micro magnet is small, but bulk packs can create a measurable outside field.
Mitigation: Use keepers, spacing, shielding, and package-field checks before air shipment.
These examples show when the quick check should move forward to sample validation and when the buyer should change geometry, grade, retention, or compliance path.
Input: 1/16 x 1/16 x 1/32 in N52 block, fixed plastic pocket
Result: Plausible if gap is low and polarity is controlled; validate surface flux and pocket retention on samples.
Input: Micro N52 block pulling through coating and air gap
Result: High risk of disappointing force; a larger magnet, steel return path, or disc format may work better.
Input: Loose or detachable high-powered micro magnets
Result: Do not quote as a commodity part until CPSC scope, retention, labeling, and ingestion-risk controls are resolved.
Input: 1,000-100,000 pieces packed for line-side use
Result: Feasible only with tray packaging, counting method, polarity audit, and shipment field controls.
These are intentionally not presented as hard conclusions because public evidence is insufficient for the exact finished part or the packed shipment.
Pending sample test
Public N52 material sheets do not publish a finished-part pull guarantee for this exact geometry and target condition.
Pending lab method
Flux index depends on the finished magnet and ASTM F963 test procedure, not just the grade name.
Supplier-specific
Coating thickness and edge coverage vary by plating system, batch control, and acceptance criteria.
Package-specific
FAA screening is based on the packed item measured at distance, so quantity and shielding matter.
Quote-specific
Rare-earth supply concentration and export controls make date-stamped supplier quotes necessary.
The FAQ is focused on procurement decisions: alias handling, dimensions, material limits, validation, safety, and sourcing.
No. It is intentionally merged into the canonical /learn/n52-magnet page because the phrase is an alias of the broader N52 magnet intent cluster.
This page treats it as a likely 1/16 inch x 1/16 inch x 1/32 inch N52 micro block unless a buyer drawing states another missing face dimension.
1/16 inch is 1.5875 mm and 1/32 inch is 0.79375 mm, so the default block is 1.5875 mm x 1.5875 mm x 0.79375 mm before tolerance and coating.
Using 7.6 g/cm3 sintered NdFeB density, a 1/16 x 1/16 x 1/32 inch block weighs about 0.015 g before coating and lot variation.
No. N52 describes a high-energy material class. Finished pull depends on shape, magnetization, target steel, air gap, shear direction, coating, and temperature.
Not always. N52 helps when envelope is fixed and room-temperature magnetic energy is the bottleneck. Lower grades can be better for cost, heat margin, or supply stability.
Only after safety review. Loose or separable high-powered magnets can trigger ingestion and pinch hazards, especially when parts are accessible to children.
Include a drawing, all dimensions, tolerance, grade, coating, magnetization axis, quantity, temperature, target surface, validation tests, packaging, and end-use channel.
Ni-Cu-Ni is common for dry indoor use, but coating thickness and edge chips matter at micro scale. Use epoxy, zinc, or custom coating only after exposure and fit review.
Only if the test method is comparable. Target steel, air gap, coating, pull direction, fixture speed, and safety factor can change the number substantially.
Yes for bulk orders. Micro N52 magnets need polarity control, part counting, trays or separators, keeper/shielding review, and shipment field checks.
Avoid it when users can access loose magnets, when pull must work through a gap, when heat is sustained, or when assembly cannot control polarity and placement.
