Copper C1220 Sheet is a high-purity, oxygen-free copper sheet product with 99.90% minimum conductivity, used primarily for electrical applications such as switching and connectivity components, ground wires and shields in electronic equipment. Its composition mainly consists of pure copper (Cu) with trace amounts of other elements like iron (Fe), nickel (Ni), manganese (Mn), lead (Pb) and zinc (Zn).
Copper C1220 Sheet offers a range of advantages for many industries and applications. It is corrosion-resistant, ductile, and malleable. Due to its excellent thermal and electrical conductivity properties, it is widely used in the electronics industry for circuit boards and wiring/cables. In addition, Copper C1220 Sheet has superior heat exchanger capabilities, making it ideal for heat sinks, condensers, cooling systems, etc. The common uses include roofing, flashing & guttering, and gold plating due to its low electrical resistance & ability to form strong protective oxides when exposed to air or water.
