Alnico Grade 5 Bar Magnets

Alnico grade 5 bar magnets have exceptional magnetic properties. They offer excellent temperature stability in very high temperature environments, and can be used at temperatures up to 1000ºF (500ºC). Composed of aluminum (Al), nickel (Ni), and cobalt (Co) alloys, alnico magnets are relatively high in magnetic strength, and have a high resistance to corrosion or demagnetization.

Alnico magnets are ideal for many types of industrial, technical and consumer applications where temperature stability is critical. From magnetic pump couplings to rotating machinery, switches, meters, motors, generators, loud speakers, guitar pickups and more.

Standard Dimensional Tolerances for Alnico Bar Magnets

Generally the standard dimensional tolerance for bar magnets is +/-0.005" on both width & thickness & +/-0.015" on length.

Alnico Bar Magnet Manufacturing Methods

Alnico bar magnets are manufactured through either a casting or sintering process. They can be made into complex shapes such as horseshoes, which is not possible to do with other magnet materials.
