"Rose Bronze" is a copper alloy for mechanical components that serves as a replacement for the six types of bronze that have been commonly used until now. It possesses cutting performance, mechanical strength, sliding performance, wear resistance, corrosion resistance, and pressure resistance equivalent to CAC406, is excellent in castability, has no dezincification corrosion, and is priced almost the same. It can be used without issues in bearings, sliding materials, and transmission parts related to electrical and electronic equipment, transmission machinery, and machine tools exported to the EU. 【Features】 ■ Fully compliant with the EU RoHS directive ■ Established a system for immediate delivery of both continuous cast products and raw materials ■ An analysis sheet detailing the presence of lead and cadmium is attached to all deliveries *For more details, please refer to the PDF document or feel free to contact us.

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.
