CuCrZr Grade 2 Copper Bar C18150 Zirconium Rods With Best Price
Copper rods are much more widely used than pure iron. Every year,
50% of copper is electrolytically purified into pure copper for use
in the electrical industry. The red copper mentioned here must be
very pure, with a copper content of more than 99.95%. A very small
amount of impurities, especially phosphorus, arsenic, aluminum,
etc., will greatly reduce the conductivity of copper. Oxygen in
copper (a small amount of oxygen is easily mixed in copper
smelting) has a great influence on conductivity, and the copper
used in the electrical industry must generally be oxygen-free
copper. In addition, impurities such as lead, antimony, and bismuth
will prevent the crystallization of copper from combining together,
resulting in hot embrittlement, which will also affect the
processing of pure copper.
This kind of pure copper with high purity is generally refined by
electrolysis: impure copper (ie blister copper) is used as the
anode, pure copper is used as the cathode, and copper sulfate
solution is used as the electrolyte. When the current passes, the
impure copper on the anode gradually melts, and the pure copper
gradually precipitates on the cathode. The copper obtained in this
way has a purity of 99.99%.
Copper is a relatively pure type of copper, which can generally be
considered as pure copper. It has better conductivity and
plasticity, but poorer strength and hardness.
