Low-oxygen copper rod

Due to differences in the production processes for copper rods, the oxygen content and appearance of the finished products vary. Copper rods produced by the upward drawing process have an oxygen content of less than 20 ppm and are therefore referred to as oxygen-free copper rods; in contrast, copper rods produced via continuous casting and rolling are hot-rolled under protective atmospheres, with an oxygen content ranging from 200 to 500 ppm, though it can occasionally exceed 700 ppm.

Oxygen-free copper rod

Based on oxygen and impurity content, oxygen-free copper rods are further classified into TU1 and TU2 grades. TU1 oxygen-free copper rods achieve a purity of 99.99%, with an oxygen content not exceeding 0.001%; TU2 oxygen-free copper rods achieve a purity of 99.95%, with an oxygen content not exceeding 0.002%.

The National “Grand Cycle” of Electricity Creates New Opportunities for the Green Power Business

Recently, a reporter learned from the website of the National Development and Reform Commission that the NDRC and the National Energy Administration have in principle approved the “Plan for a Regularized Electricity Trading Mechanism Across Grid Operating Areas” (hereinafter referred to as the “Plan”), calling for full utilization of the mechanism to promote interconnection among electricity markets, enhance the efficiency of inter-grid transmission capacity utilization, and strengthen coordination and integration across all market tiers.

Copper wire is indeed widely used in the cable industry, primarily in the following areas:

Copper boasts excellent electrical conductivity and is one of the most widely used conductive materials in cables. Its low resistivity effectively reduces energy losses, ensuring efficient power transmission, while its superior corrosion resistance enables it to maintain stable performance across a wide range of environments, thereby extending the service life of cables.

Aluminum wire is a widely used metallic material.

Aluminum has a low density—about one-third that of steel—making aluminum wire relatively lightweight and well suited for applications where weight reduction is critical. In air, aluminum forms a thin layer of alumina, which provides effective corrosion resistance and makes it ideal for use in humid or chemically aggressive environments.
