No-HRE Sintered NdFeB Magnets (Dy/Tb-Free) — Performance Table + PDF Download

If you are sourcing neodymium magnets for global delivery, the fastest way to de-risk procurement is to lock down: grade/temperature, coercivity window, stability coefficients, and batch verification. This page summarizes our Dy/Tb-free (No heavy rare earth) sintered NdFeB capability and provides the downloadable spec PDF.

Who We Are — JIADA MAGNET

JIADA MAGNET is a production-driven supplier focused on sintered NdFeB magnets and magnet assemblies. We run a procurement-friendly workflow: engineering review → tooling / machining → coating → magnetization → dimensional & magnetic inspection → export packaging → compliant shipping documents. The goal is simple: stable batches, predictable lead time, and less rework for your QA and purchasing team.


  • B2B process: drawings/spec review + grade/coating suggestion + DFM feedback.
  • Quality deliverables: CoC / inspection report / batch traceability on request.
  • Export execution: packing, labeling, shielding packaging, and documentation support.
  • Customization: machining (grinding, countersunk, arcs/segments), assemblies (magnet + steel + plastic).

What “No-HRE” Means (Dy/Tb-Free) — Why Buyers Care

No-HRE (No heavy rare earth) in this context means the magnets are produced without adding Dy (Dysprosium) and Tb (Terbium) as alloying elements for coercivity boosting. Many procurement teams prefer No-HRE when the application temperature window allows, because it can improve: material supply stability, cost predictability, and regulatory / export complexity.


Practical procurement logic: You pick No-HRE grades when your design can meet performance targets at the required operating temperature (and demagnetization risk), then validate via B/H curve, Hcj window, and temperature coefficients.
Typical advantages
  • Dy/Tb-free bill of materials
  • Stable coercivity spec windows
  • More predictable long-term sourcing
Typical validation items
  • B/H curve & demag margin check
  • Hcj at operating temperature
  • Batch-to-batch consistency

Step 1 — Define Temperature Window

First lock the maximum working temperature and demagnetization risk. For example, common Tw bands in this sheet include 80°C (N series), 100°C (M series), 110–120°C (H series), and 150°C (SH series).

Step 2 — Choose Coercivity Strategy

Check Hcj first for demag resistance. Then verify Br and (BH)max for energy density. We can help you map your rotor/motor/holding design to a safe coercivity margin.

Step 3 — Confirm with Test & Reports

For production approval, request a CoC and (if needed) a B/H curve report at target temperature. This reduces hidden cost: rework, re-sourcing, and field failures.

Reminder: For high-risk demagnetization applications (motor/rotor, elevated temp, strong opposing fields), we recommend confirming Hcj margin via B/H curve test at your operating temperatures.

FAQ — Common Buyer Questions

1) Can you supply un-magnetized parts?

Yes. Many customers magnetize in-house for rotor assembly control and yield protection.

2) Can you test B/H curve at temperature?

We can support B/H curve verification and share reports based on your required test points (e.g., 110°C / 150°C).

3) What files should I send for a fast quote?
  • Drawing (PDF/STEP) + tolerances
  • Working temperature & environment (corrosion, salt fog)
  • Grade preference (or target force/flux)
  • Coating requirement (NiCuNi / Zn / epoxy, etc.)
  • Quantity & delivery destination

What We Can Do Before You Place a PO

  • Engineering review: suggest grade / coating / magnetization direction based on application.
  • Risk control: verify demag margin with Hcj window and temperature coefficients.
  • Batch stability: define inspection items (dimensions, appearance, magnetic properties).
  • Documentation pack: CoC + basic compliance docs for onboarding (as required).
  • Delivery execution: export packaging and shipping document support.
Procurement tip: If your project is time-sensitive, submit your drawing first. We can quickly respond with feasibility + lead time + risk items (coating, machining, magnetization).

Request Quote / No-HRE Grade Recommendation

Send your drawing and requirements. We will respond with grade/coating suggestions, feasibility notes, and a quotation plan.
