  • The Effects of Oxidation on Copper Sciencing

    Apr 17 2018 · Copper electrical wire and copper pipes must be cleaned with acid-free cleaners before soldering takes place. In addition care must be taken not to overheat the copper during the soldering process as excess heat produces copper oxidation and the solder won t adhere to it. Oxidation also hinders the electrical conductivity of copper wire.
