How to Define an NdFeB Magnet Specification
Understand NdFeB grade terms, temperature class, coating, tolerance and magnetization when preparing a custom magnet requirement.
Describe Your Requirement
Industry Reference: Magnetic Terms
Industry Reference: Magnetic Terms
The definitions below are industry-reference terminology, not an ASTROMAGNET performance specification.
Br
Remanence
Residual magnetic flux density after magnetization.
Hcb
Grade and Temperature Class
Grade and Temperature Class
A higher grade number should not be selected in isolation. ASTROMAGNET’s stated grade range is N25–N52; no approved public working-temperature table is available.
INDUSTRY_REFERENCE — final material and performance remain subject to the approved drawing, specification, sample and production-lot inspection.
Coating Selection
Coating Selection
Nickel, zinc, epoxy and phosphating are supported treatments. Selection depends on corrosion exposure, handling, assembly and dimensional allowance. Gold and silver plating may be arranged externally.
