ALLOYS

Alloys are a mixture that contains at least one metal.

• It can be two or more metals such as Bronze: Copper + Tin
• It can be a metal and non metal  such as  steel: Iron + Carbon 

The product we obtain from the mixture may  have a property that the original components did not  have. This makes alloys very  useful.

Alloys compared to pure metals:

• Alloying increases strength and hardness.
• Alloying reduces malleability and ductility.

The first alloy created by  humans was bronze, which is harder and stronger  than  its components.
