NdFeB
Sintered Neodymium Iron Boron magnets (Nd-Fe-B) are composed of neodymium, iron, boron and a few transition metals. They are very strong for their small size, metallic in appearance. Usually they need to be plated with Zn, Ni, Epoxy, Paralyne etc. for anti-corrosion.
Our current production capacity is 200tons per year. And the tolerance of NdFeB can be within +/ -0.03mm (Min.) for some cases. Besides that we can provide irregular shaped magnets according to the customers' request.
In addition we are also equipped with the advance inspection instruments, so we can provide different test reports regarding the plating to the customers. Now our plating can stand for up to 100 hours or longer according to customer's request (this is based on specific plating under specific test). In the meanwhile, many special coating such as Gold, Tin and Parylene is also available in our company.
Besides the sintered NdFeB, we can also provide Bonded NdFeB magnets/assemblies to our customers.
