AlNiCo magnet

AlNiCo magnet is a kind of permanent magnet alloy composed of aluminum, nickel, cobalt, iron and other trace metal elements. Its Curie temperature is very high in the current permanent magnet materials.

It is characterized by high remanence (up to 1.35T) and low-temperature coefficient. When the temperature coefficient is -0.02%/℃, the high service temperature can reach about 520℃. The disadvantages are that the coercivity is very low (usually less than 160kA/m) and the demagnetization curve is nonlinear, so the Al-Ni-Co magnet is easily magnetized and also easily demagnetized.

According to different production processes, there are Sintered AlNiCo and Cast AlNiCo.

AlNiCo magnet can be divided into isotropic and anisotropic according to material characteristics. Casting aluminum nickel cobalt by smelting production, processing cost is relatively low, suitable for the shape of simple, large size, large specifications of the production of products;

Sintered aluminum nickel cobalt is produced by powder metallurgy, which can be processed into different sizes and shapes. It is suitable for the production of small size, light weight and small specification products.

The density is lower than that of casting, but the machinability is better.
