Introduction of Great Magtech:

Advantages of GME disc magnet

1. High Grade / High performance of disc magnet:




GME highest grade: N54, 52M, 50H, 48SH, 42UH, 38EH, 33AH, etc.

















2. High Consistency of disc magnet: 




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 of disc magnet:




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 of disc magnet:




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 of disc magnet:




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

We would love to see how you have used our magnets




Simply send us a photo of your magnets in use and if we use it on
our website we will return you $10 next order (Amount more than $1000).




Note: These
magnets are very strong and contain a lot of power in a small part.
neodymium round magnets must be handled with care as they are strong
enough to break each other if allowed to hit together to hard.
