Sm-Co
The production of samarium cobalt alloys by vacuum induction melting and casting is ideal for achieving homogeneous material with precise compositional control. LCM typically supplies material in the form of powders, with size distributions tailored to give optimum properties for each customer’s processing technique. Alternatively, alloy may be supplied as cast ingot or granules crushed to specified size requirements. LCM also offers a service for taking-back sintered products from customer plants that can be re-processed into useful feedstock alloy for re-supply.
