electro magnets

CLIME Magnet Manufactory Co., Ltd, a professional manufacturer of electro magnets and devices in East China with more than 10 years experience in research, development and production of magnetic electro magnets products, was founded in 2000.

At present main products of the manufactory include electro magnets,ferrite magnets, bonded and sintered NdFeB /Smco/ Alnico rare earth permanent magnets, sintered ferrite permanent magnets, and magnetic application products, etc.
electro magnets,Magnetic material is a kind of functional material that is necessary for basic industry and frontier science. In order to keep up with the rapid developing trend of electro magnets production and application in the world, the factory backed by its year's professional experience and convenient well-situated facility, continuously promotes the development and production in the field.
We have made it our long terms policy for our innovative electro magnets products to be reliable in quality, preferential in price, faithful to contract and mutual beneficial in cooperation.

The elements of Ferrite magnets,electro magnets are ferric oxide, barium oxide and strontium oxide, etc. Ferrite magnets have higher coercive force, higher resistance to be demagnetized and higher corrosion resistance than other non-rare earth permanent magnets. The biggest advantages of such magnets are their low price. Ferrite magnets are widely used in motors, speakers, microwave devices, electronics, machines, instruments, meters, toys and crafts, etc.
