Japan's first JIS-certified factory for bronze ingots and bronze bullion.
By incorporating various chemical analysis techniques, we have made it possible to achieve stable production of high-quality metal ingots. Our strict process management system has been recognized, making us the first factory in Japan to receive JIS certification for copper alloy ingots for casting. Along with copper alloy ingots, we have established a process management system for materials, formulations, melting, casting, inspection, and other processes based on the recycling and refining technologies developed over 70 years, becoming the first factory in Japan to receive JIS certification for copper alloy castings.
