Alloys

Alloy - An alloy is a mixture of a metal and one or more elements (other metals) or carbon.

• Pure metals are arranged in a regular lattice where layers can slide over one another. The more difficult it is for the layers to move, the stronger the metal.
• Alloys are harder than pure metals because different elements have different sized atoms, which disrupts the regular arrangement and prevents layers being able to slide over each other so easily
