Copper is a metal that occurs naturally throughout the environment, in rocks, soil, water, and air. Copper is an essential element in plants and animals (including humans), which means it is necessary for us to live. Therefore, plants and animals must absorb some copper from eating, drinking, and breathing. Copper is used to make many different kinds of products like wire, plumbing pipes, and

Pure copper has an electrical conductivity value of 5.9 10 7 Siemens/m, making it the second most electrically conductive metal to silver, which has a value of 6.2x10 7 Siemens/m. As copper is far more abundant and therefore less expensive than silver, copper quickly became a popular method for transmitting electricity
Copper and brass are quickly recycled. Maybe 70% of the copper actually in use has been recycled at least once. Density of Copper. The Density of copper is 8.96 g/cm3. Density of a pure solid chemical element is always listed as the density of the equilibrium crystalline state of that element, usually at room temperature unless specified otherwise
Pure copper is usually too soft for most uses. People first learned about 5,000 years ago that copper can be strengthened if it is mixed with other metals. The two most familiar alloys of copper are bronze and brass. Bronze, the first alloy created by people, is a mix of copper that contains as much as 25% tin. Early people used bronze to make
