* Brass: an alloy of copper and zinc

* Bronze: an alloy of copper and tin

* Steel: an alloy of iron and carbon

* Pewter: an alloy of tin, lead, antimony, and copper

* Solder: an alloy of lead and tin

Alloys are often made to improve the properties of the individual metals, such as strength, hardness, corrosion resistance, or conductivity.
