Message

You may not be able to see it, but it is a company that gives back to society.

Modern society is progressing at almost a dizzying pace, but as long as our culture exists, we don’ t foresee a day when we don’ t need or use metals or alloys. And it is that culture in which we live.

In 1961, the company Osaka Tokushu Gokin Corporation(Osaka Special Alloy Co., Ltd.) was established in Osaka. This nodularizers and inoculants and other ferro alloys for cast iron manufacturing company is proud to be longest history in japan. From the founder’ s long experience, the “made in Japan” quality and large share of the market is something we aren’ t willing to give an inch on.

When you say “alloy,” most people think of robots, however our products are improving the lives of people everywhere in modern life. Because there isn’ t a textbook on how to make our alloys, you can’ t even find the answers on the internet, we are making our own way. But through a process of trial and error. We are always working toward making a better product than we made yesterday. We are looking forward toward a better future for Japan and are earnestly working toward to a bright future through metallurgy.
