Permanent AlNiCo Magnets Aluminium, Nickel, Cobalt and Iron alloy
Product Description
AlNiCo Magnet (Aluminium, Nickel, Cobalt, and Iron alloy) is obtained by casting process, shaped in cheap phenolic resin sand molds. It can operate in environments up to 500 °C with very good resistance against corrosion, therefore coatings are seldom required.
The typical final shapes such as blocks, cylinders, rings, and arcs are obtained by cutting and grinding processes of pressed standard blocks or unitary compression pre-molded parts. Extremely fine tolerances can be obtained although, because of its high brittleness, it has to be handled and assembled with care to avoid chips and cracks.
AlNiCo magnets play an essential role in many industrial and consumer products. You can find AlNiCo magnets in electric motors, electric guitar pickups, microphones, sensors, speakers, traveling wave tubes, cow magnets, etc.
