Product details

The Ferrite permanent magnet is also known as a Ceramic Magnet and are manufactured in a wide range of shapes, sizes and grades.

The most powerful permanent magnet, offers a great return for cost & performance, have the highest field/surface strength(Br), high coercivity(Hc), can be easily formed into various shapes and sizes. Be reactive with moisture and oxygen,usualy supplied by plating (Nickel, Zinc, Passivatation, Epoxy coating, etc.).

Ferrite magnets use a wide range of materials with special properties. Especially at the high end of the performance spectrum, our magnet series are suitable for all kinds of applications.

Ferrite magnets may be customized upon request, within the indicated range of HCJ and Br characteristics.

In the interests of thorough quality control in each process, we have adopted measuring methods of the Magnetic Materials Producers Association (MMPA) of the United States and the Japanese Industrial Standard (JIS) for magnetic characteristics.

Shenzhen TOPMAG sales office was established in 2012. HT Factory was founded in 2004. It is a company specialized in R&D, production and permanent magnet..Our annual output of magnet is over 5000 tons. The performance of the ferrite magnet can be up to Br 4200 Gs, Hcj 4500 Oe The products are widely used in Automobile motors, Brushless motors, Loud speakers, Wind genertor etc.
