Ferrites are sintered from iron oxides and other ingredients. Produced by powder metallurgy. The ferrite magnet has a low remanence and a small magnetic permeability. It has large coercive force and strong anti-demagnetization ability, and is especially suitable for magnetic circuit structure used as dynamic working conditions. The material is hard and brittle. Can be used in diamond cutting tools for cutting. The main raw material is oxide, so it is not easy to corrode. Operating temperature: – 40 degrees Celsius – +200 degrees Celsius.The magnetic force is usually 800-1000 Gauss,which is often used speakers and other instruments.
