Alloys are metals that are made from a mixture of two or more pure metallic elements. Alloys characteristically have greater strength and resistance from corrosion than the metals that make them. Below are some examples of alloys and their characteristics. 

Wood's metal is made from Bi, Pb, Sn, and Cd. Its low melting point allows it to be pliable enough to be used to fuse plugs. 

Brass is made from copper and zinc. Brass is ductile and can be polished well. Therefore, it is often used to coat hardware. 

Stainless steel is made of a mixture of elements, most commonly iron, oxygen, carbon, chromium, and nickel. Stainless steel resists corrosion. It is often used for tableware and appliances (such as refrigerators and ovens). 

Sterling silver is made from silver and copper. It's shiny surfaces makes sterling silver marketable for jewelry and tableware.
