ALNiCo Magnet by china-magnets-source-material.com

Alnico magnet is the first generation permanent magnetic material. It is a kind of alloy that contains aluminum, nickel, cobalt, iron and other microscope metallic element.

The Alnico magnet manufacture successfully in the 1930 s. At that time, the Alnico is the best in magnetic performance, and its temperature coefficient is very small. Therefore, the Alnico magnet is mainly used on producing the permanent motor at that time. After the 1960s, with the development of ferrite permanent magnet and rare earth permanent magnet, the alnico magnets are replaced to use in producing motor.
