Welcome to buy discount pure c12500 copper foil for sale here from our factory. Customized orders are welcome.
C12500 copper foil is a highly conductive ordinary pure copper material with a copper mass fraction of not less than 99.7% and very low impurity content, so it is also often called purple copper. It has good electrical conductivity, thermal conductivity, corrosion resistance and processing performance, but due to the high oxygen content, it may produce hydrogen embrittlement phenomenon when it is processed and used in high-temperature reducing atmosphere, so it should be avoided to be processed and used in high-temperature environments of more than 370 degrees Celsius.
