1.What is the Copper Wire
Copper alloy is made of pure copper and one or several other elements.
Pure copper like Er Cu is purplish red, also known as red copper.
The copper alloys are divided into Zinc-Copper, Silicone-Copper and Nickel- copper.
A.Nickel-Copper
Copper alloy with nickel as the main addition element. Copper nickel binary alloy is called ordinary white copper; copper alloy with manganese, iron, zinc, aluminum and other elements is called complex copper.
B. Zinc-Copper
Brass is an alloy of copper and zinc. If only by copper, zinc brass is called ordinary brass. Brass is often used to manufacture valves, water pipes, air conditioning internal and external connecting pipes and radiators.
C.Silicone-Copper
Bronze originally refers to copper-tin alloy, and copper alloy except for brass and white copper is called bronze and is often named the first main added element before the bronze name. The casting performance, friction reduction and mechanical properties of tin bronze are good and are suitable for manufacturing bearings, worm gears, gears, etc.
2. What is the application is mainly used for making electrical equipment such as generator, bus, cable, switch device, transformer and heat conduction equipment such as flat plate collector of heat exchanger, pipe and solar heating device.
A. Power transmission:High conductivity copper is needed in power transmission, which is mainly used for power wires and cables, bus bars, transformers, switches, plug-in components and couplers.
B. Motor manufacturing:Copper alloys with high conductivity and high strength are widely used in motor manufacturing. The main copper parts are stator, rotor and shaft head.
C. Communication cable: Since the 1980s, due to the advantages of large current carrying capacity of optical fiber cable, it has been replacing copper cable in the communication trunk line and rapidly applied.
D. Residential electrical circuit: With the improvement of people's living standards and the rapid popularization of household appliances, the residential power load is growing rapidly.
3.What is the most popular of copper alloy wires
A. AWS ErCu :Suitable for argon arc welding, gas welding and plasma arc welding of red copper. Such as billet continuous casting mold, steel plant electrode fixture, conductive roller, conductive plate, heating element, copper container and copper sculpture.
B.AWSErCuSi-Ait is used for argon arc welding of silicon bronze, copper, brass and copper and steel, and also for welding of steel and cast iron, such as friction surface of heavy machinery and locomotive and vehicle parts. More commonly used in argon arc welding。Zinc plate, because of its good corrosion resistance, less burn loss of galvanized layer, good corrosion resistance of brazed joint, has been widely used in automobile door frame and motorcycle parts.
