BT Metal Alloys

• 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
