Copper-clad aluminum wire adopts advanced coating welding manufacturing technology, which concentrically covers high-quality copper tape on the outer surface of core wires such as aluminum rods or steel wires, and forms a solid interatomic metallurgy between the copper layer and the core wires. Combined. Combining two different metal materials into an indivisible whole, which can be drawn and annealed like a single metal wire. During the drawing process, copper and aluminum are reduced in proportion, and the volume ratio of the copper layer remains relatively constant change.

Performance introduction:

Due to the "skin effect" characteristics of high-frequency signals, copper-clad aluminum wires and copper-clad steel wires have the same conductive properties as pure copper wires when transmitting high-frequency signals (greater than 5MHz).

Unique composite properties: Copper-clad aluminum wire has both the conductivity of copper and the low density of aluminum; copper-clad steel wire combines the electrical conductivity of copper with the high strength of steel. Tin-plated copper-clad steel wire exerts the solderability and resistance to sulfur of tin; silver-plated copper-clad steel wire improves electrical conductivity, thermal conductivity, corrosion resistance, and oxidation resistance. So it has a wide range of applications.
