BT Metal Alloys

    Cards (11)

    • Alloy is a mixture of a base metal and one or more additional elements
    • Aluminum: for surface hardening
    • Chromium: for corrosion resistance
    • Copper: resistance to atmospheric corrosion
    • Manganese: small amounts for hardening; in larger amounts for wear resistance
    • Molybdenum: combined with other alloying metals, such as chromium and nickel, increase corrosion resistance and raise tensile strength without reducing ductility
    • Nickel: increases tensile strength without reducing ductility
    • Silicon: strengthens low alloy steels and improve oxidation resistance
    • Sulfur: free machining, especially in mild steels
    • Titanium: prevents inter-granular corrosion of stainless steels
    • Tungsten, vanadium, and cobalt: for hardness and abrasion resistance
