Characteristics and application of AlNiCo magnetic material
Gauss Industrial Co.,Ltd | Updated: Jan 15, 2019

AlNiCo is one of the earliest developed permanent magnet materials and is an alloy of aluminum, nickel, cobalt, iron and other trace metals. According to the production process, it is divided into sintered AlNiCo and cast AlNiCo. The shape of the product is mostly round and square. The casting process can be processed into different sizes and shapes; compared with the casting process, the sintered product is limited to a small size, and the produced blank has a dimensional tolerance that is better than that of the cast product, and the magnetic properties are slightly lower than that of the cast product, but Processability is better. In permanent magnet materials, cast AlNiCo permanent magnets have the lowest reversible temperature coefficient and can operate at temperatures above 600 degrees Celsius. It was widely used in the 30s and 60s of the 20th century. It is now used in the instrument industry to manufacture magnetoelectric instrumentation, flowmeters, micro-motors, relays, etc.
