Our Businesses

About our business

We are manufacturing “alloys” by changing the properties of various metals including iron. It is a combination of multiple metallic elements such as silicon and magnesium, giving various functional properties to metallic materials, sometimes a hard and strong property, sometimes a soft and flexible property by adding only a small amount to molten metal. We are like a "department store of niche metals" that you hardly have an opportunity to see our products, but we are actually supporting all aspects of our lives in the background.
