Copper with content over 99.90% is Pure copper, such as Oxygen free copper, Tough pitch copper,
Phosphorus deoxidized copper. The electrical conductivity, thermal conductivity of Pure copper are high.
The copper is provided in the respective shapes such as a plate, a strip(Up to 5mm thickness), and a bar by processing the high quality pure copper ingot.
The bendability, the formability and the corrosion resistance are superior also.
The risk of hydrogen embrittlement (blowhole, cracking) during welding and brazing is low, because any oxygen is not contained. Oxygen free copper is recommended for the parts with welding and brazing.
The content of copper is around 99.90%, it contains 200-500 ppm oxygen. The electrical conductivity, the thermal conductivity are same as Oxygen free copper.
A small amount of phosphorus is added. The electrical conductivity is 85%IACS, lower than Oxgen free copper (101%IACS). Phosphorus deoxidized copper is recommended for the parts with welding and brazing, because any oxygen is not contained.
Bus bar, power module base plate, heat spreader, tab lead electrode for lithium ion battery, transformer coil material, gasket, Sputtering target
Water heaters, air conditioning piping materials, construction, electric refrigerators for water supply, fuse caps
