What are alloys?
An alloy is a homogeneous mixture of 2 or more metals or one metal and one non metal.
Examples of some alloys are Brass, Bronze, Solder, 22 Carat Gold, Stainless steel.
- Brass - comprises 80% copper and 20% Zinc. It is not a good conductor of electricity.
- Bronze - comprises 90% copper and 10% tin. Bronze is not a good conductor of electricity, despite having copper as its constituent.
- Solder - comprises 50% lead and 50% tin. It has a lower melting point than lead and tin hence it is used for welding wires together.
- Stainless steel - comprises iron and nickel/ chromium. Iron rusts but stainless steel does not rust.
