Copper clad aluminum magnesium wire adopts cladding welding manufacturing technology, the high quality copper strip concentrically coated on the outer surface of the conductor, such as aluminum rod or wire and copper layer and the core formed between firm metallurgical bonding between the atoms.Make the combination of two different metal materials as an integral whole,can be like processing a single wire drawing and annealing processing,copper and aluminum in the process of drawing with variable diameter ratio, volume ratio of copper layer remained relatively constant.
1. Electrical cable conductor material
2. Telephone line communication conductors
3. Coaxial cable inner conductor
4. Surface shielding network, etc.
5. Enameled winding wire
6. Ornament such as chains
Compared to CCA wire, the CCAM wire has following Characteristics
1- Higher tensile strength. Especially for smaller size, the wire is not so easy to break in the winding process which insures much higher production efficiency.
2- As there is magnesium element in the conductor, the electrical conductivity is lower than CCA wire.
