Welcome to our MMC Superalloy Corporation website.

Our company was established in July 2010, succeeding the business concerning special heat resistant/corrosion resistant alloys and special copper alloys from Okegawa Plant of Mitsubishi Materials Corporation. Okegawa Plant, our predecessor, began in 1944 based on the noble philosophy of Mr. Koyata Iwasaki, then president of Mitsubishi Corporation, and Dr. Jun Asado, our first plant manager, “to process nonferrous metals through which contributing to the society as well as creating comfortable environment for the employees”. Since then, we have been developing as a unique comprehensive manufacturer of nonferrous metals in the world dealing with special copper alloys, nickel alloys, cobalt alloys, and titanium alloys, etc. We will succeed such noble philosophy and aim for the reliable “Best Partner” company trusted in the world with our quality/technology and R&D force nurtured for over 66 years in the land of Musashino by sincerely responding to the needs of our customers and residents in the local community.

In order for that, I will pursue

1) World standard QPS

How we can satisfy our customers in our quality (Q), prices (P) and service (S)

2) World best secure workplace

How we can build a safe and secure workplace for our employees

3) World best trusted business

How we can be loved in the local community

I believe "adaptability" is essential as we sail out forth in the storm of paradigm shift, and we need to create new customers through our actions constantly catching changes. Especially our unique technology and materials are expected to be effective in a wide range of fields to actualize highly recycling based society and low carbon society. We will continue to gather the wisdom of all of the working here, and challenge the further possibility of super alloy which innovates the Earth environment with our "super" and "extreme" technology.

We will strive for contribution to the human beings, society and the earth, the motto of Mitsubishi Materials Group, without neglecting our lofty sense of obligation and pride, sincerely responding to our customers' requests and offering the best solution. Your continuing support and encouragement will be highly appreciated.
