The production flow chart above outlines the process of manufacturing Samarium Cobalt magnets. First developed in the 1960s, Samarium Cobalt magnets were the strongest magnet available at the time. They are now ranked second in terms of magnetic power after Neodymium magnets.
As their name would suggest they consist of two main elements being Samarium and Cobalt however they also contain a range of other elements. The following elements are also commonly present in varying amounts; Iron, Copper, Zirconium, Hafnium.

The process starts with the raw materials being melted into an alloy, which is formed into moulds and cooled. Next these ingots are broken and milled into a fine powder form. The majority of Samarium Cobalt magnets are formed using a sintering process. The powder is then formed in dies and is sintered with a high temperature to fuse the powder into a solid object.

The magnetic field is applied to the fused magnet and the process of shaping and applying the surface completes the magnet. In most cases the magnet goes through more than one magnetising process to imbue the magnet with maximum magnetic strength.

Samarium Cobalt magnets, like all magnets, are in fact a magnetic storage device. The magnet itself is an alloy of elements that are able to hold a magnetic charge. The magnet stores the remanence of magnetism that was applied to it during the manufacturing process. As is the case with other sintered magnets like Neodymium, Samarium Cobalt magnets are brittle and must be handled with care.

Samarium Cobalt magnets are the second most powerful permanent magnet on the market. However Samarium Cobalt magnets are available in a far more limited range than Neodymium magnets and Ferrite. This is due to limited raw material supply which results in a relatively high cost. These factors mean Samarium Cobalt magnets are only used in limited applications that require the combination of their strong magnetic power and their superior thermal stability.

AMF stocks Samarium Cobalt magnets in three shapes; disc magnets, block magnets and cylinder magnets. If you need a particular shape or size outside this range please don’t hesitate to get in contact for a quote on a batch of custom magnets.
