Alnico Magnets are primarily made from aluminum, nickel, cobalt, copper, iron and sometimes titanium. Alnico Magnets have a classic metallic look and the maximum operating temperature is 540 degrees Celsius.
Alnico has a low coercive force compared to Ceramic and Rare Earth Neodymium and Rare Earth Samarium Cobalt magnets. Alnico horseshoe magnets, discs, rods and blocks are commonly used in the Education Industry. Hence are painted with pole colours and pole identification.
Alnico is not suited for repelling or high friction applications, is more subjected to demagnetization, brittle and can break if dropped.
Handling: Alnico will drop its gauss rating if not stored correctly. Store with poles attracting each other or use a keeper if available. Machining: Alnico is very hard and very brittle and does not lend itself to normal machining.
