Red copper is pure copper, also known as copper, is copper element, because of its color is purple red and named.
Red copper is pure copper refined from sulfide or oxide copper ore, with good electrical and thermal conductivity, excellent plasticity, easy hot pressing and cold pressure processing, a large number of used in the manufacture of wires, cables, brushes, EDM special electro-etched copper and other products requiring good electrical conductivity.

Copper has low electrical resistivity, high mechanical strength, and good anti-corrosion performance, making it an excellent conductor for easy contact connection. However, in China, its storage capacity is not large and relatively expensive. Therefore, it is selectively used for busbar devices in important high current contact connections or places containing corrosive gases. The conductivity of aluminum is 62% of that of copper. Calculated by weight, the weight of aluminum busbars of the same length that transmit the same current is half of that of copper busbars. The increase in heat dissipation area caused by the larger cross-sectional area of the aluminum busbar is approximately 44% higher than that of the copper busbar in terms of the amount of aluminum busbar used to transmit the same current of the same length.

Copper fittings, as a common pipeline material, have excellent conductivity and thermal conductivity and are widely used in various fields. However, many people have found that brass fittings will rust after being used for a period of time. Why is this? In this article, we will uncover the reasons why brass fittings are prone to rusting, to help you better understand this phenomenon.
