Copper bar manufacturers: classification and use of copper materials
19
Copper materials can be simply divided into two categories, one of which is pure copper, and the other is the composition of various copper alloys.What is copper alloy?According to the explanation of Baidu Library, an alloy is a substance with metallic characteristics synthesized by a certain method from two or more metals and metals or non-metals..Generally obtained by melting into a homogeneous liquid and solidifying.Copper alloy, obviously means that the alloy contains copper element.It can be simply understood as a copper alloy (copper alloy) with pure copper as the matrix and adding one or more other elements to the alloy.. According to my country’s classification standards for non-ferrous metals, pure copper is divided into three types, namely, oxygen-free copper, red copper, and phosphorus deoxidized copper.The purity of oxygen-free copper copper is greater than 99.95%, due to high electrical conductivity, stable processing performance, good weldability, corrosion resistance and low temperature performance.Therefore, it is widely used in the manufacture of busbars, conductive strips, waveguides, coaxial cables, vacuum seals, vacuum tubes, transistor components, etc.; usually we say red copper refers to copper containing up to 99.Above 95%, there must be only a very small amount of impurities, because the purity of red copper is very high. Therefore, the conductivity of red copper is greatly reduced compared with other materials of copper..Red copper is widely used to make electrical equipment and heat exchangers such as generators, bus bars, cables, switchgear, transformers, etc.; the copper content of phosphorous deoxidized copper reaches 99.More than 90%, good welding performance and cold bending performance, widely used in the production of gasoline or gas delivery pipes, drain pipes, condenser pipes, mine tubes, condensers, evaporators, heat exchangers, train box parts.The classification of copper bars for copper alloys is generally divided into the following four categories: brass, bronze, copper-nickel alloy, and silver copper.Among them, brass refers to an alloy based on copper and zinc. Because of its high strength, high hardness, and strong chemical resistance, brass is widely used in heat exchangers and condensers, low temperature pipelines, and subsea transportation. Tube.Manufacture of sheets, bars, rods, pipes, casting parts, etc.; bronze originally refers to copper-tin alloys, because bronze has high strength, good sliding friction resistance, excellent cutting performance and good welding performance, in the atmosphere , Fresh water has good corrosion resistance, etc. For this reason, bronze is widely used in springs, reeds and other elastic components and pipe fittings, chemical equipment, wear-resistant parts and anti-magnetic parts, as well as in the production of aviation, automobiles, tractors and other industries. Parts that bear friction; cupronickel is a copper-based alloy with nickel as the main additive element. It has good ductility, high hardness, beautiful color, corrosion resistance, and deep drawing performance. It is widely used in shipbuilding, petrochemical industry, electrical appliances, instrumentation, and medical treatment. Equipment, daily necessities, handicrafts and other fields, and also an important resistance and thermocouple alloy.The disadvantage of copper-nickel alloy is the main additive element-nickel is a scarce strategic material, and the price is relatively expensive; silver-copper is a binary alloy of silver and copper, its outstanding feature is strong resistance to sulfide, good electrical conductivity, fluidity and Wetting, good mechanical properties, high hardness, wear resistance and welding resistance.Widely used to make contacts, conductive rings and fixed contact pieces for air circuit breakers, voltage controllers, telephone relays, contactors, starters and other devices.Vacuum brazing filler metal, commutator, also can make coins, decorations and tableware, etc..
