Product Description

raw material:
Oxygen-free copper rods are generally produced with electrolytic copper plates, and 8mm copper rods can be directly drawn out by using an up-drawing furnace. The oxygen-free copper rods produced by this process are pure copper that does not contain oxygen or any deoxidizer residues. In fact, it is still Contains very trace amounts of oxygen and some impurities. According to the national standard, the content of oxygen is not more than 0.02%, the total content of impurities is not more than 0.05%, and the purity of copper is more than 99.95%.

Classification:
The copper rod produced by the above-mentioned method has a proper oxygen content below 20ppm, which is called an oxygen-free copper rod. It has electrolytic copper plate as the raw material and has low resistivity, so it is mainly used for products with strict resistance requirements. The copper rod produced by the above-mentioned method is in a soft state. According to the oxygen content and impurity content, oxygen-free copper rods are divided into TU1 and TU2 copper rods. The purity of TU1 oxygen-free copper rod reaches 99.99%, and the oxygen content is not more than 0.001%; the purity of TU2 oxygen-free copper rod reaches 99.95%, and the oxygen content is not more than 0.002%.

The copper rod produced by continuous casting and rolling is hot-rolled under protective conditions, and the oxygen content is in the range of 200-500ppm, but sometimes it is as high as 700ppm or more. In general, the copper rod produced by this method is called hypoxic rod. The copper rod has a bright appearance, commonly known as a bright rod. The copper rods produced by continuous rolling and continuous casting are in a hard state. Recycled copper is used to solve the supply of raw materials for copper rods. Hypoxic rods that meet national standards are generally used to produce wires and cables, communications, and automobiles.
The electrical properties and mechanical properties of the copper wires drawn by them are in line with the technical indicators of national standards. In addition, there are generally 12.5mm, 17mm, 20mm copper rods.

use:
Oxygen-free copper rod is a high-quality raw material for wire drawing, producing wire copper core and enameled wire.

my country is the country that produces the most copper in the world today, and it is widely needed because copper has good electrical conductivity, good physical properties and excellent process performance, can pull out micron-scale filaments, and has sufficient strength. The main use is as electrical equipment, accounting for about 50% of the copper consumption. Copper has been used for thousands of years and has the longest application practice of all metals, but it may also be the earliest exhausted resource of all metals, so it is precious.
