Copper is an extremely durable metal and is often used in products designed to last a very long time, such as building wire, water pipes, and tube fittings. As jewelry, copper will last a lifetime or longer, when cared for properly. Copper is sometimes used as a base for jewelry on top of which another metal is plated, such as silver or platinum.
Apr 12, 2017 · Properties of Copper Copper is a highly malleable metal that can be shaped and bent without breaking when either cold or hot. Copper has been used for thousands of years, and is a very ductile metal, meaning it can be stretched out to form thin wire. Copper conductors are available as hard-drawn, medium-hard-drawn, and soft-drawn. Hard-drawn copper has the greatest strength, but is difficult to work with. Because of the difficulty in shaping hard-drawn copper, its uses are limited. Sep 18, 2011 · Which of the following fall into intensive or extensive...
