Remarks:

1. The above mentioned data of properties are given at room temperature.

2. Temp. Coefficient is calculated ranging 20-100 °C for grades with Hcj<20kO, and 20-150 °C for grades with Hcj>=20kOe.

3. The maximum operating temperature of magnets is shape/geometry dependent.

4. These are standard grades and others are available upon request. Where practical we will produce grades for specific applications.
