Also known as ferrite magnets ferrite magnetic pen that we usually see little black magnets. Its raw materials are mainly composed of iron oxide, barium or strontium. After the magnetization, the residual magnetic field strength is high, and the residual magnetic field can be maintained for a long time. Commonly used as permanent magnet materials. For example: speaker magnets. Dongyang Kim Dae-ferrite magnetic factory supply, professional manufacturer of ferrite magnetic soft screen door, ferrite performance, reasonable price, widely used in various fields!
