Copper Alloy-Yegang Steel (Shandong) Group Co., Ltd.

Copper alloy is an alloy formed by adding one or several other elements to pure copper as the matrix. Pure copper is purple-red, also known as copper. The density of pure copper is 8.96, the melting point is 1083℃, and 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, transformers, etc. Commonly used copper alloys are divided into three categories: brass, bronze and cupronickel.
There are three classification methods of copper alloys: according to the alloy system, it can be divided into unalloyed copper and alloyed copper. Unalloyed copper includes high-purity copper, tough copper, deoxidized copper, oxygen-free copper, etc. It is called red copper or pure copper, also called red copper, while other copper alloys belong to alloy copper. In my country and Russia, alloy copper is divided into brass, bronze and cupronickel, and then small alloy series are divided into large categories.
Divided by function, there are copper alloys for electrical and thermal conductivity (mainly unalloyed copper and microalloyed copper), copper alloys for structure (including almost all copper alloys), corrosion-resistant copper alloys (mainly tin brass, aluminum brass) , various non-white copper, aluminum bronze, titanium bronze, etc.) wear-resistant copper alloys (mainly complex brass, aluminum bronze, etc. containing lead, tin, aluminum, manganese, etc.), free-cutting copper alloys (copper-lead, copper- tellurium, copper-antimony and other alloys), elastic copper alloys (mainly antimony bronze, aluminum bronze, beryllium bronze, titanium bronze, etc.) damping copper alloys (high manganese copper alloys, etc.), artistic copper alloys (pure copper, simple single copper, tin bronze, aluminum bronze, cupronickel, etc.). Apparently, many copper alloys are multifunctional.
According to the material forming method, it can be divided into cast copper alloy and deformed copper alloy. In fact, many copper alloys can be used for both casting and texturing. Usually wrought copper alloys can be used for casting, while many cast copper alloys cannot be deformed such as forging, extrusion, deep drawing and drawing. Cast copper alloy and deformed copper alloy can be subdivided into red copper, brass, bronze and cupronickel for casting.

Application Scope

Copper uses and application areas
Power Industry:	Power transmission such as line cables, transformers, switches, plug components and connectors; motor manufacturing such as stators, rotors, shaft heads and hollow conductors; communication cables and residential electrical lines also require a large amount of copper wires.
Electronics industry：	Electric vacuum devices such as high-frequency and ultra-high-frequency launch tubes, transition tubes, magnetrons, etc., require high-purity oxygen-free copper and dispersion-strengthened oxygen-free copper.
Energy and petrochemical industry:	The main condenser tube sheets and condenser tubes in thermal power plants in the energy industry are made of brass, bronze or cupronickel.
Transportation industry:	In the shipbuilding industry, copper alloys include aluminum bronze, manganese bronze, aluminum brass, gun metal (tin-zinc bronze), white copper and nickel-copper alloy (Monel), etc., which are all standard materials for shipbuilding. In warships and merchant ships, copper and copper alloys are generally used as aluminum bronze propellers, bolts, condenser tubes, rivets, copper-containing coating paint, etc. In the automotive industry, copper and copper alloys are mainly used in radiators, brake system pipelines, hydraulic devices, gears, bearings, power distribution and power systems, brake pads, washers, and various joints, accessories and trims. Motors, rectifiers and control, braking, electrical and signaling systems on railway trains also rely on copper and copper alloys to work. In addition, the electrification of railways has created a large demand for copper and copper alloys.
Mechanical and metallurgical industry:	In addition to the large amount of copper used in motors, circuits, hydraulic systems, pneumatic systems and control systems, mechanical engineering also requires various transmission parts and fixing parts, such as cylinder liners, connectors, fasteners, gears, twisting parts, etc. Use copper or copper alloy to reduce wear and lubricate. The key component in the continuous casting technology of metallurgical equipment, the crystallizer, is mostly made of high-strength and high thermal conductivity copper alloys such as chromium copper and silver copper. The vacuum arc furnace and electroslag furnace water-cooled crucible in electrometallurgy are made of copper pipes. , various induction heating induction coils are wound with copper tubes or special-shaped copper tubes, with water cooling inside.
Light industry:	Copper and copper alloys can be used to manufacture heat exchangers for air conditioners, clock movements, paper machine meshes, rollers, printing copper plates, fermentation tank linings, distillation pots, building decoration components, etc.
Emerging industries and high-tech fields:	Copper is also used in emerging industries and high-tech fields, such as cladding of superconducting alloys, containers and pipelines for ultra-low temperature media, cooling inner villages of rocket engines, and magnet windings of high-energy accelerators.
