A common alloy is a mixture of two or more metals. TIN, STEEL, PEWTER, and stainless STEEL are all examples of common alloys. TIN is a soft, malleable metal that is often used in combination with copper to form bronze. STEEL is an alloy of iron and carbon, and is one of the strongest and most widely used metals. PEWTER is an alloy of TIN, copper, and antimony, and is used for decorative items and jewelry. Stainless STEEL is an alloy of iron, chromium, and nickel, and is resistant to corrosion and rust.
