Alnico Magnet

AlNiCo magnet are the earliest industrially produced magnetic materials. They are divided into two types according to the production process, cast AlNiCo and sintered AlNiCo. Excelled in temperature stability, they have very important applications which low-priced ferrite magnets and high-performance neodymium magnet cannot compete with. AlNiCo magnet have the advantages of high remanence, low temperature coefficient, and a maximum operating temperature of 550 °C.

The alnico magnets are widely used in various fields such as instruments and meters, electromechanical sensing, electroacoustics, etc. We are capable of processing AlNiCo products with complex shapes and high dimension precision special requirements such as heat treatment of multipolar orientation, circular orientation, plane, inner circle, outer circle multipole magnetization and radiation magnetization of specific products.
