Product Description
AlNiCo magnet have two types, sintered AlNiCo and cast AlNiCo.
Sintered Alnico magnets are manufactured using a powder metallurgy process which uses controlled atmosphere, high temperature sintering to produce near net shape parts. These may range in size from as little as. 05g to 150g. Semi automated production enables adjustment of materials, and processing allows either a standard range of magnetic properties or individually tailored alloys to meet customer specifications.
Sintered AlNiCo offer slightly lower magnetic properties but better mechanical characteristics than the cast AlNiCo. Sintered AlNiCo magnets are most suitable in small sizes. The sintering process is well suited to large volume production, and results in parts which are structurally stronger than cast magnets. Relatively close tolerances can be achieved without grinding
Cast magnets are manufactured by pouring a molten metal alloy into a mold and then further processing it through various heat-treat cycles. The resulting magnet has a dark gray exterior appearance, and may have a rough surface. Machined surfaces have a shiny appearance similar to steel.
Cast AlNiCo magnets have excellent direction of orientation due to their unique crystalline grain orientation. They are designed to produce high magnetic output in a specified direction.
Cast AlNiCo 5 is the most popularly used among all the cast AlNiCo magnets. It is used widely in rotation machinery, communications, meters and instruments, sensing devices and holding applications. The higher resistance to demagnetization (coercive force) of Alnico 8, Cobalt content to 35%, allows this material to function well for short lengths or for length to diameter ratios of less than 2 to 1.
