戸畑製作所 Company Profile

A manufacturer of non-ferrous metal casting, processing, and welding! We produce high-quality products trusted by the global industrial community.

Tobata Seisakusho Co., Ltd. was established in 1948 in Tobata as a specialized manufacturer of copper and copper alloys, and has relocated its base to the Sone area of Kokura Minami Ward over half a century ago. We manufacture copper products for blast furnaces and electric furnaces for steel manufacturers both domestically and globally. In recent years, we have successfully developed flame-retardant magnesium alloys, which are gaining attention as lightweight materials aimed at reducing environmental impact, and we are also challenging ourselves in new fields.
