1.Copper clad aluminum wire is produced with the production process of cladding welding drawing method, by cladding planished copper stripe concentrically on the outer surface of the aluminum core, via several times of drawing and heat treatment, to meet customers' technical requirement on line diameter, mechanical property and electrical property. 2.The copper clad aluminum wire characterizes by both the small density of aluminum and the good condutivity of copper. 3.This kind of bimetallic composite wire is suited for most electrical conductor applications. 4.The processing method of CCA wire is similar to that of copper wire during cable manufacture.
