C12200 is a high purity copper alloy, also known as EDM red copper. It consists mostly of copper and a small amount of phosphorus. C12200 has good electrical conductivity, thermal conductivity and corrosion resistance, and is often used in electronic components, semiconductor equipment, chemical industry and other fields.v

C12000 welding performance and cold bending performance is good, generally no "hydrogen disease" tendency, can be processed in the reducing atmosphere, use, but not in the oxidizing atmosphere of processing, use, mainly to pipe applications, can also be plate, belt or bar, line supply. Used as gasoline or gas transmission pipe, drain pipe, condenser pipe, mine pipe, condenser, evaporator, heat exchanger, train

C12000 copper bar is made from a high-purity electrolytic copper, also known as ETP copper (Electrolytic Tough Pitch Copper). Its main component is copper, going above 99.9%, and it also contains small amounts of impurity elements such as oxygen, iron and sulfur.

C10200 copper bar is made from anly pure copper material known as oxygen free copper, with 99.95% purity. Given itsly low oxygen content, C10200 copper bar has excellent electrical and thermal conductivity, as well as good welding and processability.

C10100 copper bar is made from anly pure copper alloy containing more than 99.99% copper content, leading to its excellent electrical and thermal conductivity. This high-purity copper is highly favorable in the electrical and electronic industries requiring high conductivity and processability.

C11000 copper bar is a very common option in electrical applications given its extremely high electrical and thermal conductivity.
