Material data
Published SmCo grade finder
Search ten documented grades. Compare up to three grades and download the visible records, with units and test temperatures included.
Filter grades and test conditions
Values apply at the stated test temperature. Scroll wide tables horizontally.Swipe the table sideways for all properties. The grade stays visible; each row has its own test temperature.

Specification confirmation H-series maximum temperature differs between supplied documents: 350 °C in the grade table and 300 °C for XGS 35H in the English brochure. Request the current grade specification before design approval.
Published maximum temperature is not a universal operating guarantee. Geometry, reverse field, load line and exposure conditions determine suitability. Br = remanence; Hcj = intrinsic coercivity, not Hcb.
