Notes
The above data was developed with reference to the Chinese national standard GB/T 3560
Testing method according to the magnetic material testing standard GB/T3217
For high temperature characteristics, specifications should be determined according to customer requirements.
Conversion between SI and CGS: 1t = 10kGs，1 koe = 79.6ka/m，1 mgoe = 7.96kj/m3
The maximum operating temperature refers to the irreversible magnetic flux loss during an open circuit test; le; 5%， And the temperature point when the PC value of the magnet is L/D=0.7.

Inorganic coating | Phosphate/ Passivated | Grey | ＜2 | N/A | N/A | 1H | ＜250 |
Bluing | Blue | ＜2 | N/A | N/A | 2H | ＜250 |
The above data represent the best performance. The actual specification is to be adjusted according to variable product size and shape.
Muli-layer coatings is a combination of different type of coatings. It' S color, thickness and working temperature may vary from different combinations.
Test condition of PCT: 121°C, 100% humidity, 2 atms
Test condition of HAST: 132"C, 95% humidity, 2.7 atms. HAST is to evaluate the weight loss of magnet after testing, the lower the better.
