Low Weight Loss NdFeB Magnets for Motors 20180919
Series of low weight loss products
NdFeB magnet manufacturers of China have developed a series of weight loss magnets by optimizing the composition, microstructure and surface coating of magnets. The weight loss of HAST magnet (130 °C, 2 atm, 95% humidity) is less than 1 mg/cm2. At the same time, the manufactures have teamed up with the related nano-technology research institute of the university to develop nano-glaze coating surface protection technology, which has been used to prepare high corrosion resistant magnets.
Serious of low temperature coefficient product
NdFeB magnet manufacturers of China are committed to the development and stable production of automotive motor magnet and wind power magnet, mass production of multi-brand/model high consistency and low temperature coefficient magnets, mass production of SHT series of large size wind power arc magnets, magnetic Fluctuation value <±1%, 120°Cx2h average thermal demagnetization rate <1%; mass production of 38UH-38AH series automotive motor magnets products, the coercivity temperature coefficient of N38UH product in 20-150 °C temperature range is as low as -0.47% / ° C, which can work continuously in the cold shock environment of -40 ° C ~ 160 ° C for more than 2000 hrs, the remanence temperature coefficient of N38 AH magnets work in 20-150 ° C temperature range is as low as -0.09% / ° C, the working temperature can be 240 ° C.
Serious of no/low heavy rare earth material product
A variety of non/low heavy rare earth magnets have been industrially produced. Through the optimization of the formula and the optimization of the slab structure, the grain size of the magnet is refined, and the microstructure is also optimized, which reduces the dependence of the high-performance magnet on the heavy rare earth element dysprosium and terbium, and reduces the material cost.
No heavy rare earth material series: N52/N54, N50M, N45H (48H), N38SH (40SH)
Lower heavy rare earth material series: N52M, N50H and N42SH
Serious of grain boundary diffusion product
The grain boundary diffusion technology can reduce the usage amount of heavy rare earth, effectively save heavy rare earth resources, reduce the production cost of magnets, and improve the comprehensive cost performance of products.
For the magnets with the same performance, the grain boundary diffusion process technology uses less heavy rare earth compared with the conventional process, the grain boundary diffusion process can produce magnets with higher comprehensive performance.
Ultra-high performance NdFeB magnets such as N52SH, N50UH, N45EH, N40AH can be prepared by the grain boundary diffusion process, and some of the magnets have Hcj(kOe)+(BH)max(MGOe)>78.
