BoM spec for Voron Printers, these are N52H grade rather than N35 or N42 commonly seen on Ali. Price is per magnet.

These are N52H grade magnets! To my knowledge a first in the UK at least, these combine the strength of N52 (which has a working temp of 80C, and starts to reversibly lose strength at that point), with higher working temps of 125C.

Each magnet has a vertical pull of 1425g flush to a mild steel surface.
