Examples are aluminium, copper, lead. zinc and tin.
Compounds
Most metals do not occur in their natural state. They are often found as compounds such as metal oxides, sulfides and halides.

Alloy
Mixtures of metals, called alloys, are more commonly used than the pure metal. By alloying, some of the important properties of metals can be improved.
Solder, which is used in the electronics industry, is a mixture of tin and lead. One type of solder (63% tin and 37% lead) has a lower melting point but is harder than either of the metals
proccessing
-
Metal processing. In industry, molten metal is cooled to form the solid. The solid metal is then mechanically shaped to form a particular product. ... Grains in metals tend to grow larger as the metal is heated.
recycling
Recycling is the process of converting waste materials into new materials and objects. ... Recycling can prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, thereby reducing: energy usage, air pollution (from incineration), and water pollution (from landfilling)..
