For the quality of the electric motor magnet,We focus on the following ten point:1)Dimension;2)Appearance ; 3)Magnetic moment; 4)Demagnetization curve; 5)Irreversible loss ; 6)Corrosion; 7)Mechanical property; 8)Glue ;9)Subassembly;10)Packing.
Most customers require neodymium motor magnets with high maximum working temperature, such as 35SH, 38SH, 35EH, 35UH, use some small arc magnets to form a ring magnet, magnetization direction is throughdiameter, NS and SN. And some require other shapes such as segment, wedge shape, block, ring, or special shape.
Zinc coating is thinner than the NiCuNi coating,the normal coating thickness is 6um.
It is the environmental Cr3+ Zinc , so you don't need to worry about the pollution.
Its anticorrosion ability is a little weaker. So it can be used in shortterm anticorrosion
environment. Its advantage is beautiful in appearance because of its color ,its permeability is better than NiCuNi.
The test always done for Zn coating is 24h salt spray test,the max working temperature is 160ºC.
