Can one page give a fixed arc magnet price?

No. Public pages can show catalog examples and budget ranges, but custom arc magnet price depends on drawing, material, grade, coating, magnetization, quantity, testing, tooling, and lead time.

What information changes an arc magnet quote the most?

Material family, grade temperature class, heavy rare-earth exposure, arc geometry, tolerance, coating, magnetization fixture, testing, quantity, and tooling status are the main quote drivers.

Is the estimator a supplier quotation?

No. It is a budgetary screening tool for RFQ preparation. Supplier confirmation is still required before purchasing or releasing a design.

Why is arc magnet price kept as one hybrid page?

The query mixes immediate price-estimate intent and research intent, so this route provides the estimator first and then evidence, methodology, risk, and RFQ guidance on the same canonical URL.

Arc magnet price tool + report

Arc magnet price estimator for budget ranges before RFQ.

Enter material, geometry, quantity, coating, tooling, testing, and lead time. The tool returns a budgetary unit-price band, uncertainty flags, and the next RFQ action.

20-180 deg

Arc angle range

4 materials

NdFeB, ferrite, SmCo, Alnico

Unit + batch

Recurring and tooling view

Budgetary, not a supplier quotation

The range is useful for planning and RFQ preparation. Final price still depends on supplier drawing review, yield, tooling, magnetization fixture, and commercial terms.

Report summary

The useful answer is not a single number.

Arc magnet price is best handled as a scoped budget band with explicit evidence gaps. The table below gives the decision summary behind the estimator.

Most reliable first answer

Budget band + quote evidence

A fixed universal arc magnet price is weaker than a scoped range tied to drawing and quantity.

Custom quote swing

Model spread, not market fact

The estimator can widen into multi-x ranges when grade, coating, tooling, and testing differ. Public evidence is insufficient to publish one verified custom-market multiplier.

Fastest price path

Catalog SKU match

Only use it when OD, ID, arc angle, length, magnetization, and grade are acceptable as-is.

Highest uncertainty

Heavy rare-earth grades

Dy/Tb exposure and high-temperature coercivity requirements increase volatility and lead-time risk.

Methodology

How the estimator turns geometry into a budget band.

The tool uses deterministic rules: arc volume, material family, grade band, quantity scale, coating/test evidence, tooling status, and lead-time pressure. Unknowns widen the band instead of pretending precision.

Formula logic

Arc volume is approximated from mean diameter, arc angle, radial thickness, and length. The cost model then applies material, grade, coating, test, geometry-complexity, quantity, and lead-time factors.

Price bands are deliberately wider than a quote because public data rarely includes supplier yield, magnetization fixture, tooling reuse, freight, currency terms, and inspection scope.

Cost stack

Key numbers

Material family changes the price story.

These are budget-model inputs, not market price promises. They explain why a ferrite, NdFeB, SmCo, or Alnico arc can produce very different quote behavior.

Material	Model basis	Where it fits	Price caveat
NdFeB	$0.52 / cm3 baseline	Highest energy density; price sensitivity rises with Dy/Tb exposure and high-temperature grades.	Range factor 1.80 before evidence and tooling adjustments.
Ferrite	$0.12 / cm3 baseline	Lower material cost but larger geometry may be required for the same magnetic output.	Range factor 1.45 before evidence and tooling adjustments.
SmCo	$0.96 / cm3 baseline	High-temperature stability; samarium/cobalt exposure and machining can raise quote spread.	Range factor 1.95 before evidence and tooling adjustments.
Alnico	$0.38 / cm3 baseline	Useful for temperature stability but less common for modern compact motor arc segments.	Range factor 1.55 before evidence and tooling adjustments.

Evidence

Source quality and disclosure are visible.

The estimator uses source categories rather than copying supplier prices. Public catalog pages prove price visibility for standard items; supplier and standards pages explain why custom prices need evidence.

Evidence boundaries

What is verified, what is only a budget assumption.

The estimator now separates public evidence from internal budget logic. Use the verified signals to shape RFQs, and treat the boundaries as places where supplier confirmation is mandatory.

Decision question	Verified signal	How to use it	Boundary / unknown
Can public sources prove a live arc magnet price?	Catalog pages can show SKU-level prices, while custom suppliers usually require drawing, grade, orientation, quantity, and review before quoting.	Use catalog prices only for SKU-fit prototypes. Treat custom pages as RFQ evidence, not a price list.	Public evidence is not enough to confirm live custom unit prices or supplier yield.
When does high Hcj change the quote?	ASTM A1101-16 describes a broad NdFeB property range, including HcJ from 875 kA/m to above 2785 kA/m and special grades outside common ranges.	High-temperature or demagnetization-risk motors should quote coercivity target and test evidence, not just an N-grade label.	The standard defines property context; it does not publish supplier surcharges.
Why include magnetic testing as a cost driver?	IEC 60404-5 defines measurement of B, J, H, demagnetization curve, and recoil line for permanent magnet materials.	A quote with demagnetization-curve evidence is not equivalent to dimensional-only inspection.	The page does not claim IEC testing is required for every prototype order.
How does EU supply risk affect price comparison?	The European Commission states 2030 critical-material benchmarks and says rare earths used for permanent magnets are refined in China.	EU programs should ask for sourcing, recycling, traceability, and disruption assumptions before comparing landed costs.	This is supply-chain risk context, not a quoted surcharge for every EU shipment.
When do U.S. tariffs enter the RFQ?	USTR identified permanent magnets for a 25% Section 301 rate in 2026 as part of its China tariff modifications.	U.S.-bound RFQs should separate ex-works unit price, Incoterms, HTS classification, tariff responsibility, and exclusions.	Tariff applicability depends on origin, classification, timing, and current exclusions; buyer customs review is still required.

Updated evidence note: June 8, 2026

Public sources support catalog-vs-RFQ boundaries, standards scope, supply-risk context, and tariff questions. They do not provide reliable live custom arc magnet market prices, so the numeric range remains a budget model until supplier quote review.

Comparison

Choose the price path before comparing suppliers.

A catalog price, custom RFQ, and engineering-review budget are different buying paths. Mixing them creates false savings.

Catalog product

Bench prototypes, fixtures, early geometry checks

Price signal: Visible unit price, limited configuration freedom

Risk: May not match pole arc, magnetization, coating, or thermal duty

Custom RFQ

Pilot lots and production-intent motor arcs

Price signal: Supplier quote after drawing, grade, quantity, and process review

Risk: Tooling, fixture, and test costs can be missed in a simple unit-price request

Engineering review

High speed, high temperature, IP-sensitive, or safety-critical programs

Price signal: Budget only until FEA, retention, and validation evidence are aligned

Risk: Premature price comparison can select the wrong magnet family or grade

Risk limits

Where arc magnet price estimates fail.

The estimator is useful when assumptions are visible. It is not valid when commercial, geometry, or validation requirements are hidden.

Mistaking catalog price for production price

Prototype savings can disappear when tooling, yield, and inspection are added.

Mitigation: Separate catalog-fit check from custom RFQ and ask for recurring and non-recurring costs.

Ignoring grade temperature class

A lower unit price can fail demagnetization or retention validation.

Mitigation: State operating temperature, duty cycle, back-iron condition, and coercivity target.

Quoting without magnetization evidence

A cheaper magnet may require a different fixture or deliver the wrong field direction.

Mitigation: Attach magnetization diagram and request fixture capability confirmation.

Understating compliance destination

Documentation, traceability, and coating proof can change cost and timing.

Mitigation: Name destination market, standard expectations, and sample approval gate in the RFQ.

Comparing ex-works and landed prices as if they match

Tariffs, Incoterms, freight, insurance, and customs classification can move the buyer-paid cost after the unit quote looks competitive.

Mitigation: Ask each supplier to state Incoterms, origin, HTS/customs assumption, tariff responsibility, freight exclusion, and quote validity.

Treating standards as free documentation

A dimensional quote can look cheaper than one that includes magnetic curve evidence, sampling, certification, packaging, and traceability.

Mitigation: Separate dimensional inspection, IEC-style magnetic evidence, coating proof, certificate scope, and PPAP-style documents as line items.

Scenarios

Three common price-use cases.

Use the tool result differently depending on whether you are buying a prototype SKU, launching a pilot RFQ, or entering engineering review.

Prototype catalog check

24 pieces, standard NdFeB, existing SKU-like geometry, basic inspection

Use catalog comparison first, then quote only if magnetic orientation or size does not match.

Pilot BLDC rotor

1,200 pieces, high-temperature NdFeB, new arc tooling, magnetic evidence

Budget as RFQ-ready; compare unit cost plus tooling, coating qualification, and sample lead time.

Launch-pressure EV program

Heavy rare-earth grade, production PPAP evidence, 18-day target lead time

Treat price as engineering-review budget until supplier capacity and validation plan are proven.

U.S.-bound China-origin magnet buy

Custom NdFeB arc magnets, PRC origin risk, supplier quote excludes duties

Compare landed cost separately from ex-works unit price; confirm HTS classification, Section 301 exposure, Incoterms, and quote validity before supplier ranking.

EU program with supply-risk review

Permanent magnets for a strategic program with sourcing and recycling questions

Ask for origin, refining/magnet-making chain assumptions, recycling or take-back evidence where relevant, and alternate-source feasibility before accepting a low unit quote.

RFQ checklist

Minimum fields for a price you can compare.

If any field is unknown, mark it explicitly. Suppliers can then quote assumptions instead of silently filling gaps.

2D drawing with OD, ID, arc angle, length, chamfer, tolerance

Material family and grade or magnetic property target

Coating and corrosion or adhesive-process requirement

Magnetization direction, pole pattern, and fixture assumption

Batch quantity, annual volume, sample quantity, and quantity ladder

Operating temperature, RPM, duty cycle, and retention method

Inspection level, magnetic test method, certificate needs

Packaging, destination market, and compliance expectations

Target lead time, tooling ownership, and quote validity period

Incoterms, origin, HTS/customs assumption, and tariff responsibility

Whether magnetic curve, flux, coating, and certificate evidence are included or quoted separately
