Low weight lose product series
Optimizing the ingredients of the magnet, Micro-structure and coating of the surface, our company has developed a series of low- weight- loss magnet , the weight loss of which can be lower than 1 mg/cm² after the corrosion HAST test(130 ℃, 2atm, 95%humidity).
Meanwhile, we work with Institute of Nanotechnology in Zhejiang University to develop the protection technology for the surface of Nano coating. That technology has already been used to produce magnet with high corrosion-resistance.
HREE rare earth-free/HREE rare earth-low product series
We have already mass produced kinds of ( HREE) Heavy Rare earth-free/(HREE) Heavy Rare earth-low magnet; Through Optimizing the ingredient and Cast slice structure, the particle size of the magnet is refined and the micro-structure is also optimized, which decreases the reliance of (HREE) Heavy rare earth—Dy and Te and decreases the material cost for High grade NdFeB magnet . (HREE) Heavy rare earth-free series : N52/N54, 50M, 45H(48H), 38SH(40SH) (HREE) Heavy rare earth-low series of grade 52M, 50H, 42SH
Grain boundary diffusion product series
Grain boundary diffusion technology can reduce the use volume of the (HREE)Heavy rare earth so that it can save the (HREE) Heavy rare earth material effectively, and decreases the production cost of the magnet as well as enhance the comprehensive cost performance of the product.
Aiming at the magnets with same grade, compared with traditional process technology, grain boundary diffusion process technology uses less (HREE) Heavy rare earth and this technology can make the magnet with higher comprehensive cost performance.
With grain boundary diffusion process technology, super-high grade magnet can be made, like 52SH, 50UH, 45EH, and 40AH. HCJ of some magnet(kOe)+(BH)max(MGOe)＞78.
Lamination magnet series
Lamination rare earth magnet is proved that it can reduce the eddy current loss for the high-efficiency motors. The reduction of the eddy current loss can decrease the heat and enhance the efficiency. Nowadays, new-energy Auto, aerospace as well as Intelligent industrial robot markets are addicted to pursuing the balance of motor power and calorific value, so the demand of lamination rare earth magnet has kept increasing. With respect to your designing team and project requirement, we can help you to realize the magnetic customization of the following contents by using the licensed process manufactured lamination rare earth magnet in LEC Magnetics:
* Insulation thickness：50μm-100mm
* Insulation layers：2-40 layer(Magnet thickness limits the layers)
* Max working temp. of the magnet：60-400℃
* Temp.Resistance of the magnet surface coating：200-500℃
* Corrosion resistance of the magnet surface coating：Neutral salt spray resistance can be over 1000 hrs and PCT can be over 500 hrs.
We can also provide magnetic assembly, even the complete motor rotor.
