Application
Purple copper bar the use of the more expansive than pure iron,
each year, 50% of the copper electrorefining is pure copper, used
in the electrical industry. Here copper, really have to be very
pure, copper above 99.95%, very small amounts of impurities,
especially phosphorus, arsenic, aluminum, etc., can greatly reduce
the conductivity of the copper. Oxygen in copper (copper easily
when mixed with a small amount of oxygen) had a great influence on
conductivity, used for electrical industry generally must be
oxygen-free copper brass. In addition, the impurities such as lead,
antimony and bismuth can make the crystallization of copper can not
be together, cause heat brittle, also can affect the pure copper
processing. The purity of high pure copper, typically by
electrolysis refining: put not pure copper anode (i.e., crude
copper), pure copper cathode, copper sulfate solution as
electrolyte. When an electric current passes through the anode
impure copper melting gradually, pure copper precipitation will
gradually on the cathode. Such a refined and copper; Purity can
reach 99.99%
Feather of our bars
Features: high purity, fine, low oxygen content. Pore-free,
trachoma, osteoporosis, and excellent electric conductivity,
electric erosion of the mold surface of high precision, the heat
treatment process, the electrode omnidirectional, suitable for
fine, fine, good thermal way, processability, ductility, corrosion
resistance and weather resistance, etc.
