The introduction of T2 copper tube, what are the differences between soft and hard T2 copper tubes

T2 copper plate is a pure copper rolled plate of domestic grade T2, and the copper content of the corresponding American grade C11000 and Japanese grade copper rod is extremely high, and the total content of impurities is not greater than.

Copper has a purple-red appearance, high electrical and thermal conductivity, good corrosion resistance and easy processing. Therefore, according to different uses, it is mostly processed into plates, strips, foils, pipes, bars, wires, wire rods, heterosexual copper and copper castings. T2 copper plate belongs to copper plate.

Copper plate is divided into hot-rolled plate and cold-rolled plate, the thickness of hot-rolled plate is generally 425mm, the thickness of cold-rolled plate is between, the width is 2500mm, and the length can reach 6000mm. The thickness of the copper plate can reach 50mm.

Uses of copper: Copper has excellent electrical conductivity, good corrosion resistance and processability, and can be fusion welded and brazed. T1 and T2 copper are mainly used as electrically conductive, thermally conductive and corrosion-resistant components, such as wires, cables, conductive screws, shells and various conduits.

T3 copper is mainly used as a structural material, such as making electrical switches, gaskets, rivets, nozzles and various conduits; It is also commonly used in some less important conductive elements.

Copper tube, also known as copper tube. A kind of non-ferrous metal pipe. It is a pressed and drawn seamless tube.

The trace impurities in copper have a serious impact on the electrical and thermal conductivity of copper. Among them, titanium, phosphorus, iron, silicon, etc. significantly reduce the conductivity, while cadmium and zinc have little effect. The copper mentioned here must indeed be very pure, and the copper content must reach more than that.

A very small amount of impurities, especially phosphorus, arsenic, aluminum, etc., can greatly reduce the electrical conductivity of copper. The oxygen content in copper (a small amount of oxygen is easy to mix in copper smelting) has a great influence on the electrical conductivity, and copper used in the electrical industry generally must be oxygen-free copper. In addition, impurities such as lead, antimony, and bismuth will make the crystallization of copper unable to bind together, resulting in hot embrittlement, which will also affect the processing of pure copper.

This kind of pure copper with high purity is generally refined by electrolytic method: impure copper (i.e., blister copper) is used as the anode, pure copper is used as the cathode, and copper sulfate solution is used as the electrolyte. When the current passes, the impure copper on the anode gradually melts, and the pure copper gradually precipitates on the cathode.

the copper thus refined; The purity is achievable.

Generally, the copper tube can be divided into hard form and soft form, the so-called hard copper tube is drawn or squeezed after the copper tube is successful, do not do other treatment, so that it is naturally formed, at this time the copper tube, the tissue form is all in a full state, the tissue composition of the copper tube is particularly brittle, the copper tube is not easy to bend, the hard copper tube can only appear in the form of a straight pipe, Luoyang Haotai Copper can be customized according to the different needs of customers to make different states of copper tube, The product quality is strictly implemented in accordance with national standards, and the use is safe and reliable.

Soft copper tube, because its production process and hard copper tube production process is similar, and hard copper tube compared with an annealing process, copper tube annealing, is what people say in the high temperature furnace calcination, in order to change the arrangement of the element structure in the tube, after annealing the copper tube, its structure will become soft, which is conducive to the bending of the copper tube, after annealing the copper tube, it is called soft copper tube.

Because of its structural dissimilarity, rigid copper pipes can only produce straight pipes and cannot be bent, so they are widely used in power plants, electrical equipment switches and other industries. The ** of hard copper pipes is slightly cheaper than soft copper pipes.

Although the name of the soft copper pipe is a flexible tube, it can also be used instead of a hard tube, so the flexible tube is more widely used than the hard tube, and its existence mode can also exist in the form of a coil in addition to the straight pipe, because the advantage of the coil is that the length is longer, when it is used in a longer connection point, it can be freely intercepted according to the required length, so as to avoid the appearance of leakage holes when the copper tube is welded, therefore, the soft copper tube is mostly used in air conditioners, refrigerators, It is used in places that need to be bent, such as mechanical tubing.

We know that there are four kinds of ordinary copper (T1, T2, T3, T4), but the only grades suitable for making copper tube copper are T1 and T2.

The following is a list of chemical compositions of T1, T2:

The chemical composition of T1 is Cu+, and the chemical composition of T2 is Cu+, in summary, we can analyze that T2 copper tube has more excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance due to fewer impurities than T1. Therefore, the T2 copper tube made of T2 copper has high electrical conductivity, thermal conductivity, ductility and corrosion resistance, and is the best choice for the manufacture of heat exchange equipment (such as condensers, etc.) and high-precision hydraulic testing systems. At the same time, due to the above excellent characteristics, it is widely used in the production of generators, busbars, cables, switchgears, transformers and other electrical equipment and heat exchanger pipes, solar heating devices and other thermal conduction equipment.
