Shandong Wholesale Brass Rod C11000 C1100 Pure Copper Rod Copper Round Rod Copper Round Bar

The red copper rod is named for its purple color. It has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and can be welded and brazed.

It is not necessarily pure copper, and sometimes a small amount of deoxidizing elements or other elements are added to improve the material and performance, so it is also classified as a copper alloy. Chinese copper processing materials can be divided into: ordinary copper (T1, T2, T3, T4), oxygen-free copper (TU1, TU2 and high-purity, vacuum oxygen-free copper), deoxidized copper (TUP, TUMn), adding a small amount of alloy Elements of special copper ( copper, tellurium copper, silver copper) four categories. The electrical conductivity and thermal conductivity of red copper are second only to silver, and are widely used in the production of electrical and thermal conductivity equipment. Copper has good corrosion resistance in the atmosphere, seawater and some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkalis, salt solutions and various organic acids (acetic acid, citric acid), and is used in the chemical industry.

use:
The use of red copper rods is much wider than that of pure iron. Every year, 50% of copper is electrolytically purified to pure copper for use in the electrical industry. The red copper mentioned here really needs to be very pure, containing more than 99.95% copper. A very small amount of impurities, especially phosphorus, 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 electrical conductivity, and copper used in the electrical industry must generally be oxygen-free copper. In addition, impurities such as lead, antimony, and bismuth will make the crystals of copper unable to combine together, causing hot brittleness and affecting the processing of pure copper. This high-purity pure copper is generally refined by electrolysis: using impure copper (that is, blister copper) as the anode, pure copper as the cathode, and copper sulfate solution as the electrolyte. When the current passes through, the impure copper on the anode gradually melts, and the pure copper gradually precipitates on the cathode. The copper obtained in this way; the purity can reach 99.99%.
Red copper is a relatively pure copper. Generally, it can be approximated as pure copper. It has good electrical conductivity and plasticity, but its strength and hardness are poor.
