Metallic chromium

Metallic chromium

Metallic chromium is excellent in heat and corrosion resistance, and can be used safely. It is used for a broad range of purposes, and indispensable for various applications including superalloys, stainless steel, and electronic materials.
Our company handles metallic chromium of a broad range of grades, including the purity level 2N (99.0%) and 4N (99.99%). There are various product shapes, including flakes, briquettes, grains, and powder, according to grade. In addition, our company has standard products to meet a wide array of needs from clients. In addition to the standard products, we can customize products for special purposes of use.
