Alnico is an alloy that contains varying amounts of Aluminum, Nickel and Cobalt hence the name Alnico. Typically, Alnico formulas have very high temperature capabilities, up to 540˚C although they are not as powerful as other types of magnets and is less stable so they will lose their magnetism with time.
Alnico has a classic metallic appearance, and can be made with quite complicated pole structures depending on the purpose of the magnet. Traditional Horseshoe and Bar magnets are usually made from Alnico as it is the weakest form of permanent magnet that is strong and wont break or shatter.
