Sintered NdFeB Blocks
Workhorse block magnets · Grades N35 — N52 · High-temp SH/UH/EH variants
DESCRIPTION
Sintered NdFeB blocks deliver the highest commercial energy density of any permanent magnet, used across high-power motors, sensors, and holding fixtures. We source directly from upstream Chinese sintering plants and cover the full grade range from N35 through N52, plus high-temperature SH/UH/EH variants and custom geometry. Each lot ships with a Material Certificate; demagnetization curves are available per grade on request.
