toroidal

We produce a toroidal core with permalloy i.e., a nickel steel plate of high permeability. We are the first and the largest permalloy, nickel steel possessing company in the domestic market, supplying quickly heat treating furnaces, with various sizes and materials and from small quantity to large one, to our clients according to their requests (producing the maximum size of 2100 π in an external diameter).
Particularly, we prevent contacting layers by developing coating technique of raw material and equipment as the first one in China, and realize 100% of the property requested by our clients.
