ALLOY 110 E.T.P (ELECTROLYTIC TOUGH COPPER)

Electrolytic Tough Pitch Copper, also reference as Copper Alloy 110 is the most common copper item on the market. It has the highest electrical conductivity of any metal except silver. The chemical composition contains minimum purity of 99.9% copper, with approximately 0.04% oxygen. When exposed to the elements, it produces a relatively impervious protective film which eventually forms the familiar green patina of weathered copper. In most environments, its corrosion resistance is excellent to good, although it is not suitable for use with certain material. For instance: acetylene, ammonia, chromic acid, nitric acid, mercury or mercury salts.

It is produced in a variety of states, including sheet, strip, plate, wire, rod, bar, tube, and extruded shapes. It has a wide range of applications because of its corrosion resistance, conductivity, and visual appeal. It has a high ductility which makes it great for drawing, forming and machining. With increasing degrees of cold work, it hardens but slowly and therefore is capable of being worked extensively before annealing is required. Due to its high conductivity, it is used exclusively in transformers, switch gear, magnets, and a variety of other electrical applications.
