Manufacturing Process
Alloy Formulation and Melting
High-purity Neodymium (Nd), Iron (Fe), Boron (B), and selected alloying elements are accurately proportioned and melted in a vacuum environment. Vacuum melting effectively prevents oxidation and guarantees uniform chemical composition throughout the alloy.
Strip Casting and Rapid Solidification
The molten alloy is rapidly solidified through strip casting to produce thin, uniform alloy flakes. This controlled cooling process refines the microstructure and provides a consistent foundation for high magnetic performance.
- Hydrogen Decrepitation
The alloy flakes undergo hydrogen decrepitation, during which hydrogen is absorbed into the material, causing it to fracture into coarse powder. This step enhances material brittleness and improves milling efficiency while preserving magnetic characteristics.
- Micronization by Jet Milling
The coarse powder is further refined into micron-sized particles using jet milling in an inert gas atmosphere. Precise control of particle size and distribution is critical for achieving high coercivity and optimal grain alignment.
Usage Precautions
NdFeB magnets are brittle; avoid impact or sudden collision.
Keep magnets away from high temperatures beyond the rated limit.
Store in a dry environment to prevent corrosion.
Strong magnetic force may cause pinching injuries; handle with care.
Keep away from electronic devices and magnetic-sensitive components.
