A reddish-brown element that conducts heat and electricity very well. It is also used as a primary roof material as well as a flashing component. Copper turns a greenish color after being exposed to the weather for a length of time and appears in the middle of the Galvanic Series.
It is one of nature's elements. It is also used for various parts of equipment and plumbing in swimming pools and spas. Corrosive water caused by misuse of chemicals, improper water balance or placing trichlor tablets in the skimmer can cause copper to be dissolved from the equipment or plumbing and deposit the precipitates on hair, fingernails or pool walls. High levels of copper also cause green water. Copper is also used as an algaecide. Maximum level about 0.2 ppm.
Copper is a soft metal often used in jewelry. It is used in making bronze, brass, and gold alloys. Copper turns green as it ages, and copper exposed to weather will age faster.

CAS Number: 7440-50-8. Copper is a reddish metal that occurs naturally in rocks, soil, water, and air. It also occurs naturally in plants and animals. Metallic copper is easily molded or shaped, and can be found in the U.S. penny, electrical wiring, and some water pipes. It can also be found in mixtures (called alloys) with other metals such as brass and bronze. Copper is also found as part of other compounds forming salts. Copper salts occur naturally, but are also manufactured. The most common copper salt is copper sulfate. Most copper compounds are blue-green in color. Copper compounds are commonly used in agriculture to treat plant diseases like mildew, for water treatment and, as preservatives for wood, leather, and fabrics. Chemical formula = Cu. Molecular weight = 63.55 g/mol.

Metallic element, chemical symbol Cu, widely used as a coinage medium for 2,500 years. Pure or almost pure copper was used for subsidiary coinage in many countries until the mid-nineteenth century, but has since been superseded by copper alloys which are cheaper and more durable: bronze (copper and tin), brass (copper and zinc), Bath metal or bell metal (low-grade copper and tin), aluminium-bronze (copper and aluminium), potin (copper, tin, lead and silver) or cupro-nickel (copper and nickel). Copper is also alloyed with gold to give it its reddish hue, and is normally alloyed with silver in coinage metals. When the copper exceeds the silver content the alloy is known as billon.
