To achieve better tensile strength, using aluminum magnesium alloy rod as the core wire, then cladding copper layer on the surface, after drawing several times, then copper clad aluminum magnesium wire is made.
Advantages: Same as CCA Wire, it has low density, easy to solder and high strength.
Disadvantages: As the conductor contains magnesium, the resistivity compared with pure CCA wire is higher. It is not conductive to make conductor for transporting current.

Properties |
CCAM combines the advantages of Aluminum and Copper. Lower density allows weight reduction, elevated conductivity and tensile strength compared to CCA, good weldability and solderability, recommended for very fine sizes down to 0.05mm |
Application |
CATV coaxial cable, large capacity communication network signal electric LAN, control signal cable, cable shielding line, metal hose etc. Aspects. |
The Tech & Specification parameters of our company’s wires are in international unit system, with the unit of millimeter (mm). If use American Wire Gauge (AWG) and British Standard Wire Gauge (SWG) , the following table is a comparison table for your reference.
