Product Description

Disc AlNiCo Permanent Magnet

Alnico magnet is an alloy magnet made from aluminum (Al), nickel(Ni), cobalt(Co), copper(Cu), iron (Fe) and other metal elements. According to the different processing technology, Alnico magnet was classified into two types: Cast AlNiCo and sintered Alnico. Cast Alnico magnet has high magnetic flux density and it can be processed into different size and shape. Sintered Alnico of simple process can be pressed directly into the size.

Advantages of AlNiCo

1. For it'small temperature coefficient, the magnetic performance are staunch when the temperature changes.
2. The highest working temperature can reach 400 degrees Celsius, so it is widely used in instruments, meters, in which the requirements of high temperature stability of products.
3. Possess a high ability in resistant to rust, so it don't need to plating processing on its surface.
4. Cast aluminum nickel and cobalt owns a high magnetic performance, 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.
