Copper wire is a vital component in numerous industries, serving as a conduit for electricity and a foundation for intricate electrical systems. Traditional round copper wires have long been the standard, but the emergence of flat copper wire has revolutionized the field.

The chemical composition of flat copper wire primarily consists of copper (Cu) and may include small percentages of other elements to enhance specific properties. Pure copper exhibits excellent electrical conductivity and thermal stability. Flat copper wire may also contain small amounts of silver (Ag) or phosphorus (P) for enhanced electrical or soldering properties.
