Copper
Copper Product Guide
Copper alloys are often reddish or pinkish in color. They are well-known for their flexibility and ductility, which contribute to their ease of working and their conduction of heat and electricity. However, when exposed to water, copper forms an oxide coating, or patina, which may be polished off. Hence, it is often designated for use in commercial applications where there is a requirement for either flexibility in roofing or plumbing. For example, it serves as an electrical conductor for electromagnets, bus bars, and electrical motors.
In domestic and residential architectural purposes, it is often employed for the primary purpose of its color, especially for cutting board or kitchens backsplach. Also, it serves as a heat transmission quality in pots and pans.
In addition to Electrolytic Tough Pitch (ETP Copper), pure copper (alloys 101–110) is also known as ETP Copper.
