Oxygen free copper／Tough pitch copper／Phosphorus deoxidized copper
C10100 / C10200 / C11000 / C12200
Oxygen free copper and tough pitch copper are used for;—：Bus bar, power module base plate, heat
spreader, tab lead electrode for lithium ion battery, transformer coil material, gasket, Sputtering
target
Phosphorus deoxidized copper is used for;—：Water heaters, air conditioning piping materials,
construction, electric refrigerators for water supply, fuse caps
Production and sales of bars will be discontinued in March 2028.
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 Oxygen free copper (101%IACS). Phosphorus deoxidized copper is recommended for the parts with welding and brazing, because any oxygen is not contained.
