LCM is a wholly independent manufacturer of Nd-Fe-B alloys, licensed by the original patent holder, Sumitomo Special Metals Co. Ltd. Considerable expertise in raw material selection, processing conditions and product characterisation has resulted in a well-earned reputation for delivery of consistent alloys, meeting the most demanding of technical specifications. LCM also offers a scheme for taking-back sintered magnet materials from customer plants, which are re-processed into useful feedstock alloy for re-supply.
