  • Characteristics and Application of Chromium Metal

    Chromium mainly exists in the form of chromite FeCr2O4 in nature. It is produced by reduction of chromium oxide with aluminum or by electrolysis of chrome alum or chromic acid. Chromium can be used as an alloy element in stainless steel to enhance the hardness of stainless steel.
     
    Chromium plating process
    Chromium is often used as a chromium coating. Chromium plating process is generally divided into three types: decorative coating, hard chromium coating and black chromium coating. The decorative chromium coating is usually plated on the outside of the nickel layer as the top layer, and the coating has a delicate polishing effect like a mirror. As a decorative post-treatment process, the thickness of chromium coating is only 0.006 mm. The sputtering targets commonly used for chromium coating are as follows:
     
    Chromium Sputtering Target Nickel Chromium Sputtering Target Chromium Oxide Sputtering Target Chromium Silicide Sputtering Target
    Chromium Nitride Sputtering Target      

    Chromium material properties
    Chromium has the characteristics of high finish, excellent corrosion resistance, hard and durable, easy to clean and low friction coefficient. It is often used as various coating materials. It can be made into chromium powder, chromium pellet evaporation material, chromium sputtering target and other products.
     
    Typical application of chromium
    Decorative chrome plating is the coating material of many automotive components, including door handles and buffers. In addition, chrome is also used in bicycle parts, bathroom faucets, furniture, kitchen utensils, tableware, etc. Hard chrome plating is more widely used in industry, including ram in job control block, jet engine components, plastic mold and shock absorber. Black chrome plating is mainly used in musical instrument decoration and solar energy utilization.
