Copper; wire, of copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver)

HS v2017 Code: 740822

About copper; wire, of copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver)

HS code 740822 covers copper wire made from copper-nickel base alloys, also known as cupro-nickel, or copper-nickel-zinc base alloys, also known as nickel silver. These alloys are valued for their corrosion resistance, electrical conductivity, and decorative properties, making them essential in a wide range of industries, from electrical engineering to construction and consumer goods.

Production process

The production of copper wire under HS code 740822 typically involves several key steps. First, the copper-nickel or copper-nickel-zinc alloy is melted and cast into billets or rods. These are then drawn through a series of dies to reduce the diameter and increase the length, creating the wire. Annealing may be performed at various stages to maintain the wire's ductility. Finally, the wire may undergo additional processing such as plating, coating, or insulation to meet specific application requirements.

Production inputs

The main inputs for the production of copper wire under HS code 740822 include copper, nickel, and zinc as the primary raw materials. Specialized machinery such as wire-drawing equipment, annealing furnaces, and plating/coating lines are also essential. Additionally, energy sources, such as electricity or natural gas, are required to power the production processes.

Production outputs

The primary output of HS code 740822 is copper wire made from copper-nickel or copper-nickel-zinc alloys. These wires find applications in a variety of industries, including 853710 Boards, panels, consoles, desks, cabinets and other bases for electric control or the distribution of electricity, 854420 Coaxial cable and other coaxial electric conductors, and 950420 Articles and accessories for billiards. The versatility of these alloy wires makes them a valuable component in numerous electrical, electronic, and decorative products.
