The source temperature column assumes L/D = 0.7 and does not establish a safe temperature for any finished component. Some source grades, values and units require review; the full original is retained unchanged. Confirm current specifications, availability and batch results before samples or supply.
Hcj · Intrinsic coercivity
An indicator for resistance to irreversible demagnetization, evaluated with temperature, opposing field and magnetic circuit conditions.
(BH)max · Maximum energy product
One measure for comparing materials. Also check demagnetization requirements and validation results for the actual component.
