We founded the company as a manufacturer dedicated to copper and copper alloy products in 1948, and we relocated to the present site in Sone of Kokuraminami-ku half a century ago. We manufacture copper products for blast furnaces and electric furnaces used in steel production companies of Japan and the world.

In recent years, we have successfully developed flame-retardant magnesium that has attracted industry’s attention since it helps weight-saving efforts for reducing environmental burdens. The effort is one of our challenges in a new field.

We will continue to make further efforts to fulfill our customer’s requirements.
