2mesh copper mesh to 200 mesh copper wire mesh made in china

The copper mesh have a serious impact on the electrical conductivity and thermal conductivity of copper in trace impurities. The titanium, phosphorus, iron, silicon significantly reduced the conductivity, while cadmium and zinc has little effect. The solid solubility of oxygen, sulfur, selenium and Tellurium in copper is very small, can generate brittle compounds and copper, not for conductive effect, but can reduce the processing of plastic. Ordinary copper heating in a reducing atmosphere containing hydrogen or carbon monoxide in hydrogen or carbon monoxide, easy and grain boundary of cuprous oxide (Cu2O), high pressure steam or carbon dioxide gas, can make the copper rupture. This phenomenon is often referred to as the "disease of copper hydrogen". Oxygen in copper welding harmful. Bismuth or lead and copper to form low melting point eutectic, the copper hot and brittle; bismuth is film shaped distribution in grain boundaries, and the copper cold crisp. P can significantly reduce the conductivity of copper, but can improve the fluidity of liquid copper, improve the weldability. The amount of lead, tellurium, sulfur can improve the machinability. The room temperature tensile strength of copper sheet annealing is 22 ~ 25 kg / mm 2, the elongation is 45 ~ 50%, Brinell hardness (HB) ranged from 35 to 45. The copper net stay Shielding net The industry is the best shielding effect .
With doubt we listen to your detailed answers to manufacturers of wire mesh, The copper mesh Suggests that can play the shielding effect of the screen, what is the screen, in fact, there are many kinds of wire mesh products, flying star company production of silk screen copper wire braided copper net, stainless steel braided stainless steel mesh is made of metal wire products is called the screen, you know what is the screen, will ask, the shield with what kind of screen, I give you the answer slowly, copper mesh products include: The copper net Net, brass, copper net. Stainless steel products include: stainless steel wire mesh, stainless steel wire mesh, stainless steel net, mat type, can be used as a shield, can be used, there will be a better effect of various grades and ranks, and what kind of reasonable price, more convenient to use.
