Ferrite
Product Introduction:
Ferrite is the most widely used type of permanent magnetic material, manufactured via powder metallurgy. It is primarily classified into two types—barium (Ba) and strontium (Sr)—and further divided into anisotropic and isotropic grades. Ferrite is a permanent magnet that resists demagnetization and corrosion, with a maximum operating temperature of up to 250°C. It is relatively hard yet brittle, allowing it to be cut and machined using tools such as diamond‑coated abrasives, and can be formed in a single step using alloy‑steel molds. These materials are extensively employed in applications such as permanent‑magnet motors and loudspeakers.
Product Features:
| Made by powder metallurgy. | Relatively hard and brittle |
| Not easily demagnetized | Good corrosion resistance |
