Xiangyun imported copper price

Xiangyun imported copper price Dongguan Xiangyun Metal Products Co., Ltd. [Red copper manufacturer, red copper performance, red copper price] Red copper is industrial pure copper, its melting point is 3°C, there is no allotropic transformation, the relative density is., which is magnesium. Five times. Approximately heavier than ordinary steel. It has a rose red color and turns purple after an oxide film is formed on the surface, so it is generally called red copper. It is copper containing a certain amount of oxygen, so it is also called oxygen-containing copper.
Purple copper is named after its purple-red color. It is not necessarily pure copper. Sometimes a small amount of deoxidizing elements or other elements are added to improve the material and performance, so it is also classified as a copper alloy. China's red copper processing materials can be divided according to their components: ordinary red copper (,,), oxygen-free copper (, and high-purity, vacuum oxygen-free copper), deoxidized copper (,), special copper with a small amount of alloying elements added (arsenic copper, tellurium Copper, silver and copper) four categories. The electrical conductivity and thermal conductivity of red copper are second only to silver, and it is widely used in making electrical and thermal conductive equipment. Copper has good corrosion resistance in the atmosphere, seawater and certain non-oxidizing acids (dilute), alkalis, salt solutions and various organic acids (acetic acid, citric acid) and is used in the chemical industry. In addition, red copper has good weldability and can be made into various semi-finished products and finished products through cold and hot plastic processing. It has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. It is mainly used to make electrical equipment such as generators, busbars, cables, switchgear, and transformers, as well as thermal conductive equipment such as heat exchangers, pipes, and flat-plate collectors of solar heating devices. Commonly used copper alloys are divided into three categories: brass, bronze, and white copper. The uses of red copper are much wider than that of pure iron. Every year, some copper is electrolytically purified into pure copper and used in the electrical industry. The red copper mentioned here must indeed be very pure and contain more than . Very small amounts of impurities, especially phosphorus, arsenic, aluminum, etc., can greatly reduce the conductivity of copper. The oxygen contained in copper (a small amount of oxygen is easily mixed during copper smelting) has a great influence on the conductivity. Copper used in the electrical industry must generally be oxygen-free copper. In addition, impurities such as lead, antimony, and bismuth will prevent the copper crystals from being combined together, causing thermal brittleness and affecting the processing of pure copper. This kind of very pure copper is generally refined by electrolysis: impure copper (i.e. blister copper) is used as the anode, pure copper is used as the cathode, and copper solution is used as the electrolyte. When current passes through, the impure copper on the anode gradually melts, and pure copper gradually precipitates on the cathode. The purity of the copper thus refined can reach...
Red copper is a relatively pure type of copper. It can generally be considered as pure copper. It has good electrical conductivity and plasticity, but poor strength and hardness.

Usage: Can be used to make various deep-drawn and bent stress-bearing parts, such as pins, rivets, washers, conduits, air pressure gauges, screens, radiator parts, etc. It has good mechanical properties
,
It has good plasticity in the hot state and acceptable plasticity in the cold state. It has good machinability, is easy to weld and weld, and is corrosion-resistant. It is a common brass variety that is widely used. .
Feature introduction: Brass is an alloy of copper and zinc. The simplest brass is a binary alloy of copper and zinc, which is called simple brass or ordinary brass. Brass with different mechanical properties can be obtained by changing the zinc content in brass. The higher the zinc content in brass, the higher its strength and slightly lower plasticity. The zinc content of brass used in industry should not exceed
. Any higher zinc content will cause brittleness and deteriorate the properties of the alloy. In order to improve certain properties of brass, brass that adds other alloying elements to unary brass is called special brass. Commonly used alloying elements include silicon, aluminum, tin, lead, manganese, iron and nickel. Adding aluminum to brass can improve the yield strength and corrosion resistance of brass and slightly reduce the plasticity. Brass containing aluminum less than
has good overall properties such as processing and casting. The tin added to brass can significantly improve the brass's ability to resist seawater and marine atmosphere corrosion, so it is called navy brass

. Tin can also improve the cutting performance of brass. The main purpose of adding lead to brass is to improve the machinability and wear resistance. Lead has little effect on the strength of brass. Manganese brass has good mechanical properties, thermal stability and corrosion resistance. Adding aluminum to manganese brass can also improve its performance and obtain castings with smooth surfaces. Brass can be divided into two categories: casting and pressure processing products. The product specifications are complete, the price is favorable, the packaging is intact, the copper is pure, the straightness is good, the inventory is large, and the material certificate and report can be provided.
