Sintered Alnico  
Alnico magnets are made from an alloy of Aluminum, Nickle and Cobalt, hence the name. In addition to the above three, there can also be other metals added to the composition at times like Titanium and Copper. By varying the composition it is possible to tailor the magnetic properties to meet the needs of a wide variety of user ended applications.Unimagnet provide abundant Alnico magnets with excellent quality and lower price to to meet customers' requirements.

1.Manufacture process:

Alnico magnets are manufactured through casting sintering or bonded processes.
Sintered magnets are manufactured by compacting fine Alnico powder in a press, and then sintering the compacted powder into a solid magnet.
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.
