HomeMagnet MaterialsMagnet Materials OverviewWe stock most permanent magnetic materials available on the market. We specialize in manufacturing custom magnets and magnetic assemblies to meet our customers' precise specifications.NdFeB is a rare earth material available in sintered and bonded forms, as well as custom formulations.Major Characteristics
Most powerful (highest energy product) class of magnet material commercially available.
High Br, relatively high Hc, high BHmax.
Lower cost than samarium cobalt.
Temperature sensitive.
Susceptible to oxidation.
With careful design, some grades will function up at temps up to 200°C (392°F.)
Energy product ranges from 10 MGOe to 53 MGOe
Relative cost Index (by weight):40
Samarium Cobalt is a rare earth material available in sintered and bonded forms, as well as custom formulations.Major Characteristics
High Br, high Hc, relatively high BHmax
Higher in cost than neodymium iron boron
Highly resistant to oxidation
Most grades function well at temps up to 300°C (572°F)
Energy product ranges from 18 MGOe to about 33 MGOe
Relative cost index (by weight):60
Alnico magnets are an alloy consisting of aluminum, nickel, and cobalt that have been popular since the 1930s. Alnico magnets are available in both cast and sintered forms as well as custom configurations.Major Characteristics
High Br, low Hc, BHmax in the 5 MGOe range
Most temperature stable of all magnet types
Functional with no significant performance loss in temps up to 500°C (932°F).
Relatively easily demagnetized by opposing magnetic fields
Excellent oxidation resistance
Energy product ranges from 1.4 MGOe to 7.5 MGOe.
Relative cost index (by weight):25
Ferrite (Ceramic) magnets are composed of barium or strontium ferrite, have good anti-demagnetization properties, and are currently the lowest cost material. Sintered ferrite (ceramic) magnets are hard and brittle and are widely used in consumer products.Major Characteristics
Energy product ranges from 1.1 MGOe to 4.5 MGOe
Relative cost index (by weight):1.5
Rubber magnet is a magnetic material composed of ferrite magnetic powder and synthetic rubber. It is soft, elastic, twistable and easy to manufacture.Major Characteristics
Rubber magnets have a BH range of 0.6 MGOe to approximately 1.6 MGOe.
Relative cost index (by weight, based on ferrite material):1
Relative Cost by Weight
Relative Cost by BHmax
