Samarium Cobalt This particular material can be used in much the same applications as neodymium but has a much better capacity to withstand extreme temperatures. Samarium Cobalt can be used in temperatures up to 250*c. A-Mag Systems Limited can supply samarium in either disc, block or ring form as standard. Please contact us for more details regarding specific sizes etc...

Alnico Magnets

Alnico Magnets are suitable for use in extremely high temperature applications up to 500c. The material consists of an alloy of aluminium, nickel and cobalt (AlNiCo). The material possesses an extraordinary mechanical hardness.

They are manufactured by undergoing a metallurgic pressing-sintering process or casting process. The raw materials used for Alnico magnets are mixed prior to being heated in preparation for the casting process. Apart from iron, the alloy used for Alnico 500-material for example contains 24% cobalt, 14% nickel, 8% aluminium, 3% copper and 0.45% niobium. After the dosage of each component, a liquefier is added.
