Sumitomo Electric starts tungsten refining and scrap recycling operations in the United States

Sumitomo Electric Industries, Ltd. has announced the start of tungsten refining and scrap recycling operations in the United States. Sumitomo Electric Carbide, Inc., a 100% subsidiary of Sumitomo Electric, and New York Tungsten L.L.C., a subsidiary of Buffalo Tungsten Inc., a tungsten powder producer in the United States, have established a joint venture company, Niagara Refining LLC (NIRE), to produce tungsten trioxide (WO₃) from raw ore as well as recycled material. Operations are set to begin in March 2014.

Tungsten is the primary raw material in carbide cutting tools and is found in only a limited number of countries, therefore its supply can be highly volatile.

Until now, A.L.M.T Corp., a subsidiary of Sumitomo Electric, has been importing WO₃ from China and other countries to produce tungsten carbide powder as a raw material for carbide tools. A.L.M.T has also been engaged in tungsten scrap recycling at their Toyama plant since 2011. With the start of NIRE’s operations, Sumitomo Electric will be able to produce raw materials for tungsten using both methods: refining tungsten ore from tungsten mines and recycling scrap collected from the market.

Sumitomo Electric will accelerate its activities to facilitate a stable supply of tungsten raw materials, utilising WO3 production by NIRE and tungsten carbide powder production by A.L.M.T. This will allow Sumitomo Electric to control the supply chain from raw materials all the way to the finished product, which will further strengthen its competitiveness, the company stated.
