Company’s professional knowledge can offer the best help and service to the backward customers. The custom permanent magnets products are used for electrical machine, mechanisms, mould, machining, etc industry field and many mechanisms. They are also used for family, office, marketed.

Ferrite Magnets
Ferrite Magnets are composed of iron oxide, barium and strontium elements. Compared with other Non-Rare-Earth Magnets, Ferrite Magnets have higher flux density, greater coercive force, and better corrosion resistance. As one of our most popular products, Ferrite Magnets have an additional advantage because of their low cost. To make sure that Ferrite Magnets can be used despite of their hard and brittle nature, Real magnetic always applies special machining techniques while manufacturing.
