TECHNICAL GUIDE
Understand NdFeB magnet grade selection, the stated N25–N52 range and the project inputs needed for a drawing-led material review.
Discuss a Grade Requirement
The stated ASTROMAGNET grade range
ASTROMAGNET’s stated grade range is N25–N52. The number should not be used as a standalone promise of field strength or temperature capability; the approved drawing, magnetic target, geometry and operating conditions remain part of the review.
Inputs that change grade selection
Required magnetic function or target
Part geometry and available envelope
Working and peak temperature
Demagnetization and corrosion exposure
Magnetization direction
Industry reference boundary
Grade terminology is an industry reference until the project specification and approved performance basis are confirmed. Final performance remains subject to the approved drawing, specification, sample approval and production-lot inspection.
INDUSTRY_REFERENCE — do not treat this page as an ASTROMAGNET performance table.
