Alnico magnets with excellent temperature stability and mechanical strength.
"Alnico magnets" are primarily composed of iron (Fe), aluminum (Al), nickel (Ni), and cobalt (Co). They are brittle and lack ductility, so they are produced by melting and alloying the raw metals at high temperatures and then casting them into molds, which is why they are also referred to as cast magnets. They have high Br values, excellent temperature stability, and are less prone to low-temperature demagnetization and thermal demagnetization, as well as having high mechanical strength. However, due to their small coercive force (Hcj), they are susceptible to demagnetization from external magnetic fields and are not suitable for thin products, among other limitations. It is essential to choose magnetization methods that adequately consider the shape and magnetic properties in design, as well as assembly methods that pay attention to demagnetization.
