The best quality and customer satisfaction is our first priority.
Neodymium Iron Boron (NdFeB) is another type of rare earth magnetic material.
This material has similar properties as the Samarium Cobalt except
that it is more easily oxidized and generally doesn't have the same temperature resistance.
These materials are costly and are generally used in very selective applications due to the cost.
Cost is also driven by existing intellectual property rights of the developers of this type of magnet.
Their high energy products lend themselves to compact designs that result in innovative applications and lower manufacturing costs.
NdFeB magnets are highly corrosive. Surface treatments have been developed that allow them to be used in most applications.
These treatments include gold, nickel, zinc and tin plating and epoxy coating

Introduction of Great Magtech:
Advantages of GME ndfeb ring magnets
1. High Grade / High performance of ndfeb ring magnets:
GME highest grade: N54, 52M, 50H, 48SH, 42UH, 38EH, 33AH, etc.
2. High Consistency of ndfeb ring magnets:
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 ndfeb ring magnets:
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 ndfeb ring magnets:
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 ndfeb ring magnets:
coating Nickel-Copper-Epoxy is typically more than 1000 hours.
