Copper has good conductive, thermal conductivity, corrosion resistance and processing properties, including reducing impurity less conductive, thermal conductivity, trace oxygen has little influence on the electrical conductivity, thermal conductivity and processing properties, but easy to cause the "hydrogen disease", not reducing the processing and use of atmosphere at high temperature; used as conductive, heat conduction. Corrosion of equipment, such as: wires, cables, chemical evaporator, storage etc..
