Monthly price trend of neodymium magnet raw materials June 2023
Magnetic materials are materials that can react to magnetic fields in a certain way. According to the degree of magnetization, they can be divided into permanent magnet materials and soft magnetic materials. Permanent magnet materials, also known as hard magnetic materials, are mainly characterized by their high magnetic property and high coercivity. After removing the external magnetic field, they can still maintain high magnetism for a long time. Common permanent magnet materials are divided into aluminum-nickel-cobalt permanent magnet alloy, fe-chrome-cobalt permanent magnet alloy, permanent magnet ferrite, rare earth permanent magnet material and composite permanent magnet material, etc.
