Application of the countersunk magnet:
Countersunk Magnets

Advantages of strong countersunk magnets:
1. High Grade / High performance:
GME highest grade: N54, 52M, 50H, 48SH, 42UH, 38EH, 33AH, etc.

2. High Consistency:
The Cpk of Remanence (Br) and Intrinsic Coercive Force (Hcj) are much higher than 1.67.
The consistency of the surface magnetic field and magnetic flux can be controlled at +/-1%.

3. High Working Temperature:
GME strong countersunk magnets can satisfy the working temperature requirements with excellent temperature resistance.
The AH series with 40 kOe super-high coercive force can replace Smco magnets in most applications.

4. Low Weight loss:
GME super-high magnets have a long lifetime with the following specifications; PCT: 130C,humidity 100%,
vapor pressure 2.7bar, 20days,average low weight loss <2 mg/cm².
