Coming out in early 1980' s. Its main constituent is Nd2Fe14B, which has high magnetic performance.

Its maximum energy density(BHmax)is over 10 times as high as that of ferrite magnet; maximum

working temperature up to 250 centigrade. Also, it has good mechanical behavior, which can be

suitable for grinding, wire cutting and drilling and other different processing methods; Due to the

weak corrosion resistance, the surface must use the different coating to match the different

requirement.( such as coated Zn,Ni,Au,Epoxy etc.)

Proprietary technology & Advantages 

1)High Performance

The high performance SenLong Magnets can reach: N55,55M,50H,48SH,45UH,42EH,38AH,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 magneric field and magnetic flux can be controlled at +/-1%.

3）High working Temperature

   Our 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）High Anti-Corrosion

The perfect coating of Senlong Magnets can meet many anti-corrosion requirements.The salt spray test and

humidity heat test of the high anti-corrision coating Nickel+Copper+Epoxy is typically more than 1000 hours.

5）Low Weight Loss

The super-high magnets of SenLong have a long lifetime with the following specifications;PCT:130°C，

humidity 100%,vapor pressure2.7bar,20days,average low weight loss<2mg/cm2.
