Low weight loss permanent magnets

1.As poor corrosion resistance of Iron-base and Nd-rich grain boundary, NdFeB magnets can't be used until plated. Comparing with the expansion of elevator, wind turbines and permanent motors application, the customers need higher requirement on corrosion resistance of NdFeB magnets. Because the glue cohesiveness of un-plated products is much better than the plated products, Un-plated products will be better in the security. Now there are more and more customers want to use the un-plated magnets. Considering this situation, after the continuous innovation and study, our company developed ultra-low weight loss magnets (the unit of weight loss test is mg/cm2, how much milligram losing per Square centimeter). Generally speaking, the weight loss test is over 150mg/cm2 in the NdFeB industry. There is a great difference due to different Material formulation and manufacturing process. While some of our products can reach to 1mg/cm2, (Testing condition: HAST standard for 168hrs) due to the very low weight loss, the corrosion resistance is excellent, the reliability and working life of these products have been improved obviously. These products can meet the strict requirement of corrosion resistance in the application of permanent motors and other fields. They are mainly used in elevator, radar, wind generators, military aerospace, industrial motors and other fields.

2. Application which needs Low weight loss magnets
Low weight loss magnets are mainly used in elevator, radar, wind turbine generators, tide Generators, marsh gas generators, military aerospace, industrial motors and other fields.

3. Some weight loss data of our magnets

	Test condition	Standard result	TC Products
USA Standard ( PCT)	121℃±1℃,2atm,95%RH, 96 hours	<5-10mg/cm²	——
Europe Standard ( HAST)	130℃±2℃,3atm,95%RH, 168 hours	<2-5mg/cm²	<1mg/cm²

Note*: the test sample size is 10X10X10mm or Dia 10X10mm
