Chromium Metal
Metal chromium is mainly used in the production of nickel base, cobalt base high temperature alloy, aluminum alloy, titanium alloy, resistance alloy, corrosion resistant alloy, iron base heat resistant alloy and stainless steel. There are two kinds of industrial production of metal chromium, one is thermite chromium, block, silver bright color, metallic luster, containing Cr98%, according to the use of impurities have different requirements; The other is electrolytic chromium, sheet shape, dark brown surface, after hydrogen refining surface bright, containing Cr99%.
Application:
Metal chromium is an important raw material for the production of special alloys, nickel-based super alloys for aircraft turbine engines, as well as coatings for vacuum contacts, semiconductors, chips, precision electronic products, high-end optical materials, etc., which are widely used in metallurgy, electronics, aviation, aerospace and other fields.
