PRODUCTION PROCESS

Sintered magnets

Sintering is a manufacturing process for permanent magnets. It involves compacting fine AlNiCo powder at high temperatures and under high pressure.

Information

Note

Sintered AlNiCo magnets have their limitations. Compared to cast AlNiCo magnets, their magnetic performance is higher, but they are more brittle. When compared with neodymium magnets, AlNiCo magnets fall behind in terms of performance strength.

Technical Data

What the sintered AlNiCo magnet can do

The choice of sintered AlNiCo magnets depends on the specific requirements of the application, including the required magnetic performance, the shape of the magnet and the operating temperature.
