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 materials 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 soften the metal and maintain the desired properties. Finally, the wire may be coated or plated to enhance its appearance or protective qualities.

Production inputs

The main inputs required 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 systems are also essential. Additionally, energy sources, such as electricity or natural gas, are needed to power the production processes.

Production outputs

The primary output of HS code 740822 is copper wire made from copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver). These wires find applications in a variety of industries, including 854411 Winding wire, 853710 Boards, panels, consoles, desks, cabinets and other bases for electric control or the distribution of electricity, and 732690 Other articles of iron or steel. The versatility of these alloy wires makes them valuable inputs for numerous downstream manufacturing processes.
