Copper clad aluminum technology knowledge

The copper clad aluminum wire adopts the advanced cladding welding manufacturing technology, which concentrically coats the high-quality copper tape on the outer surface of the aluminum rod or steel wire core wire and forms a solid interatomic metallurgy between the copper layer and the core wire. Combine. Combining two different metallic materials into an integral whole, drawing and annealing can be performed as a single metal wire is processed. Copper and aluminum are reduced in proportion in the drawing process, and the volume ratio of the copper layer is kept relatively constant. change.

Due to the “skin effect” characteristic of high-frequency signals, copper-clad aluminum and copper-clad steel wires have the same conductivity as pure copper wires when transmitting high-frequency signals (greater than 5 MHz).

Unique compound properties: The copper clad aluminum wire has the composite properties of copper conductivity and aluminum density, while the copper clad steel wire combines the conductivity of copper with the high strength of steel. Tin-plated copper-clad steel wire plays a role of tin solderability and sulfidation resistance; silver-plated copper-clad steel wire has improved conductivity, thermal conductivity, increased corrosion resistance, and oxidation resistance. Thus has a wide range of applications. Mainly used:
