Purple copper is much more widely used than pure iron, 50% of the copper is electrolytically purified into pure copper for the electrical industry every year. Here said copper violet, indeed to be very pure, containing copper up to 99.95% or more before, a very small amount of impurities, especially phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper.
Mainly used in the production of generators, busbars, cables, switchgear, transformers and other electrical equipment and heat exchangers, pipes, solar heating devices such as flat plate collectors and other thermal conductivity equipment. Oxygen in copper (easy to mix a small amount of oxygen when refining copper) has a great impact on the electrical conductivity, copper for the electrical industry generally must be oxygen-free copper.
