The Alnico magnet is composed of neodymium magnet, nickel, cobalt, copper, iron and other materials made of an alloy. According to the different processing technology, is divided into casting neodymium nickel and cobalt and sintered neodymium nickel and cobalt two. Cast aluminum nickel and cobalt magnetic energy is higher, can be processed into the production of different sizes and shapes, sintered aluminum nickel and cobalt has the advantages of simple process, can be directly pressed into required size.

The magnet neodymium nickel and cobalt magnet has the advantages of the small temperature coefficient, and therefore subject to temperature changes caused by the magnetic energy change is very small. The maximum operating temperature up to 400-600 degrees celsius. It is widely used in instruments, meters the requirements of high temperature stability of products.

Aluminum nickel and cobalt magnet corrosion resistance strong, without surface plating processing.
