Welcome to buy discount oxygen-free copper high-quality conductive material for sale here from our factory. Customized orders are welcome.

C101 copper is made by melting and pouring copper in the presence of carbon or carbon-containing gases to absorb oxygen. This high purity and lack of deoxidizers gives it an average conductivity of 101% IACS. Oxygen-Free High Conductivity Copper Alloy (OFHC) 101 will not suffer from hydrogen embrittlement when heated in a reducing atmosphere. C10100 certifies the percentage of impurities in its composition.

The main differences between oxygen-free copper and pure copper are the differences in purity, impurity content and performance. ‌

Oxygen-free copper has a higher purity, usually reaching 99.97% or 99.95%, while pure copper has a purity greater than 99.95%, but still contains very trace amounts of oxygen and some impurities. Oxygen-free copper is divided into No. 1 and No. 2 oxygen-free copper according to its purity. No. 1 oxygen-free copper has a purity of 99.97%, an oxygen content of no more than 0.003%, and a total impurity content of no more than 0.03%; No. 2 oxygen-free copper has a purity of 99.95%, an oxygen content of no more than 0.003%, and a total impurity content of no more than 0.05%‌12.

In terms of performance, oxygen-free copper has higher conductivity, processing performance, welding performance, corrosion resistance and low-temperature performance, and no hydrogen embrittlement. In comparison, pure copper is slightly inferior in these properties‌Different characteristics, oxygen-free copper has high conductivity, good processing performance, welding performance, corrosion resistance and low temperature performance. Pure copper has good electrical and thermal conductivity, very good corrosion resistance, and good weldability.
Different functions, oxygen-free copper is mostly used in electrical and electronic products such as audio equipment, vacuum electronic devices, cables, etc. Pure copper is widely used in the production of conductive and heat-conducting equipment; it can be processed into various semi-finished products and finished products through cold and hot plastic processing; it is used in the chemical industry.
