Knowledge
Magnet materials, grades and handling
Rewritten from Ando’s own industry-knowledge pages. No third-party claims.
Materials
Permanent Magnet Materials
What Ando actually ships, and how NdFeB sits next to ferrite, AlNiCo and SmCo.
Process
Sintered NdFeB Process
From alloy to plated part — the flow Ando describes for sintered magnets.
Coatings
Coatings and Surface Treatment
Sintered NdFeB rusts if you skip the jacket. Ni-Cu-Ni is the default stack.
Grades
Br, Hcb, Hcj and (BH)max
The four numbers that actually specify a sintered magnet.
Magnetizing
Orientation and Magnetization
Anisotropy is locked at the press. Magnetizing is the last step before the part ships.
Handling
Storage and Handling
Four storage rules from Ando’s own knowledge page.
Measurement
Surface Gauss, Remanence and Flux
Three different measurements that buyers keep mixing up.
