Specified magnetic characteristics
The magnetic characteristics of materials have different standardized capacities on each grade. Those are values of matrix samples (Ratio: Height / Diameter = 0.7) calculated by a BH analyzer before cutting. The magnetic characteristics of finalized magnets after cutting depend on the shape ratio, temperature, and environment, therefore they differ from the magnetic characteristics of materials written below. Values and information currently available may change without notice due to improvements and other factors.
