Introduction of Great Magtech:

Advantages of Counterbore hole 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 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.













5. High anti-corrosion:




 coating Nickel-Copper-Epoxy is typically more than 1000 hours.
