Identification of copper materials for cables

At present, the cable in the wire and cable market can be said to be true and false, and the copper clad aluminum wire and copper clad aluminum magnesium wire are new products just listed in recent years, which gives a lot of black merchants the opportunity to use various illegal channels to pursue windfall profits. The current price of oxygen-free copper wire is around 50,000 yuan per ton, while the price of copper-clad aluminum is only 25,000 yuan per ton. (Note: oxygen free copper specific gravity 8.9, aluminum specific gravity 2.7). So, as a customer, when we go to buy a product, we can't just believe what others say. We have to shut them down ourselves. How can you tell a copper-clad aluminum cable apart?

The difference and main use of anoxic copper rod and anoxic copper rod

Generally, the cathode copper oxygen content of copper rod production is 10-50 ppm, and the solid solubility of oxygen in copper at room temperature is about 2ppm. The oxygen content of a low oxygen copper rod is generally 200 (175)-400 (450) ppm, so the oxygen is inhaled as a liquid form of copper, while the oxygen in an anaerobic copper rod of the up-drawing method is reversed. After prolonged storage in the liquid state of copper, the rods typically have oxygen levels below 10-50 ppm and as low as 1-2 PPM. From the perspective of tissue, the oxygen content of low oxygen copper rod is reduced and removed. The presence of copper oxide inclusions at grain boundaries has a negative effect on the toughness of the materials. The oxygen content of anaerobic copper is very low, so the microstructure of this copper is uniform single-phase structure, which is conducive to toughness. Pores in oxygen free copper rods are not common, but they are common defects in low oxygen copper rods.

Brief description of oxygen free copper for copper and wire and cable

Basic knowledge of copper Copper was the earliest metal used by man. As early as prehistoric times, people began to dig open pit copper mines and use the copper they obtained to make weapons, tools and other utensils. The use of copper had a profound impact on the progress of early human civilization. Copper is a metal found in the earth's crust and the oceans. The earth's crust contains about 0.01% copper, and in some copper deposits, the copper content can reach 3-5%. Copper occurs in nature mostly in the form of compounds, copper ore. Copper ore is formed by the polymerization of copper ore with other minerals, and the mined copper ore is refined into copper concentrate with high copper content.

The difference between coaxial cable and ordinary cable

CoaxialCable refers to a cable with two concentric conductors, and the conductor and the shield layer share an axis. The most common type of coaxial cable consists of a copper conductor separated by an insulating material. Outside the inner layer of insulation is another ring conductor and its insulator, and then the entire cable is wrapped in PVC or Teflon sheathing.
