1. What is a oxygen free copper pipe/tube
Oxygen free copper refers to pure copper that does not contain oxygen or any deoxidizer residue, but in fact, it still contains very trace amounts of oxygen and some impurities.
According to the standard, the oxygen content is not more than 0.003%, and the total impurity content is not more than 0.05 %, the purity of copper is greater than 99.95%.
Oxygen free copper has no hydrogen embrittlement, high electrical conductivity, good processing performance, welding performance, corrosion resistance and low temperature performance.
oxygen free copper products are mainly used in the electronics industry. It is often made into copper materials such as oxygen free copper plates, oxygen free copper strips, and oxygen free copper wires.
OFC (oxygen free copper): metallic copper with a purity of 99.995%. Generally used in electrical and electronic applications such as audio equipment, vacuum electronic devices, cables, etc.
Among the oxygen free coppers, there are LC-OFC (linear crystalline oxygen free copper or crystalline oxygen free copper): the purity is above 99.995% and OCC (single crystal oxygen free copper): the highest purity, above 99.996%, and is divided into PC -OCC and UP-OCC etc.

3. Applications and characteristics of oxygen free copper pipe/tube
High electrical and thermal conductivity, superb weldability, exceptional plasticity and ductility, great cold workability, and non-magnetic characteristics are all characteristics of oxygen free copper. After annealing, low yield strength and weak creep resistance are overcome by oxygen free copper. Experts in electronic materials highly laud it for having the qualities of high-temperature resistance, high strength, and high thermal conductivity. The electronics industry has made extensive use of copper and its alloys, particularly for components of electric vacuum instruments. a material that is frequently used in busbars, conductive tapes, waveguides, coaxial cables, vacuum seals, vacuum tubes, transistor components, etc. oxygen free copper is the top-ranking of the seven main structural materials used in vacuum electrical devices.
Application scenarios of oxygen free copper tubes
1. Cooling of electronic equipment: The cooling systems of electronic equipment, such as computers, servers, power supplies, etc., frequently use oxygen free copper tubes.
2. Car cooling system: oxygen free copper tubes are crucial to the system's operation and can increase the vehicle's cooling effectiveness.
3. The chemical industry: Heat exchangers, heaters, and other machinery in the chemical sector frequently use oxygen free copper tubes. They are resistant to corrosion and have great thermal conductivity.
