Specifications About Neodymium Magnet

Rare earth Neodymium magnet (NdFeB) is a high performance permanent magnet, which is produced by Neodymium Iron, Boron and some other rare earth elements, as the strongest permanent magnets discovered up to now, is preferred by permanent magnetic devices, due to its highly cost-effective performance based on rich rare-earth resources, manufacture in large scale and technology development. it has a wide variety of applications on the motors, generators and couplings due to its high energy and reasonable price.

High Performance:  
high performance
High Consistancy :
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%.

high consistency
High Working Temperature :
The neodymium magnet of Tianhe 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.

high work temperture
High Anti-Corrosion:
The perfect coating of Tianhe Magnets can meet many anti-corrosion requirements. The salt spray test and humidity heat test of the high anti-corrosion coating Nickel+Copper+Epoxy is typically more than 1000 hours.

high anti-corrosion low weight loss
