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.

Aluminum alloy has better heat dissipation performance between aluminum alloy and red copper.

Red copper oxidation method: 1. Soak one end of the solution and connect the other end of the cable; Taking another more plastic metal than copper, immersing it in the same aqueous solution, connecting one end of the cable, and finally plugging in two cable ends can achieve the actual effect of rapid oxidation. 2. Heating copper will form copper oxide, and if the ambient temperature is very high at this time, in a continuous high temperature environment, copper oxide will be converted into cuprous oxide and O2. When heated, copper will react with oxygen in the air, forming a gray black oxidized copper. After heating, copper transforms into a bright red color, blocking O2 from heating and turning bright red. When heated in the air, it turns gray black (oxidized and turned black). 3. Insufficient thickness of gold plating or coating falling off, oxidation at high temperatures, or long storage time of inserts or long pre drying time of inserts, in addition to atmospheric humidity, surface pollution, and impurities and vapors in the natural environment can cause red copper oxidation.

Application fields of copper pipes

The application fields of copper pipes are quite extensive, including construction industry, mechanical production, energy extraction, home appliance industry, refrigeration industry, transportation industry, communication technology, home decoration and bathroom, infrastructure construction, municipal pipeline network, etc. With the continuous maturity of copper tube production technology, the number of manufacturers supporting copper tubes is increasing year by year, and the market supply demand for the entire copper tube is relatively stable.
