Copper Clad Aluminum Wire（CCA）
Copper Clad Aluminum Wire Typical Physical Properties
Copper clad aluminum wire is a composite wire consisting of an aluminum core clad with copper stripe. The wire has high frequency electrical properties equal to solid copper. MWS Wire Industries produces a broad line or round, flat, square, and rectangular copper clad aluminum wire. Copper clad bare, plated, and film insulated. Copper clad aluminum is widely used in applications requiring the conductivity of copper while retaining much of the weight advantages of aluminum.

Detailed Selling Lead Description
1) Diameter: 2.05 - 6.00mm
2) It is mainly used as conductor under high frequency in coaxial cable taking the place of pure copper wire
3) It is divided into soft state (A kind) and hard state (H kind)
4) It is divided into 10% and 15% two kinds according to volumetric scale of copper layer
5) The DC resistively at temperature of 20 is less than0.02676.
6) Its nominal density is 3.32 - 3.63g/cm3, it is 37 - 40% of pure copper wire
7) under the same weight, its length is 2.5 - 2.7 times that of pure copper wire
8) Its surface is bright and smooth, no any defects
9) It can save a lot of copper resource
10) Its conductivity is good
11) It can reduce the production cost of the cable and it is convenient in construction
12) It has remarkable economic benefit, besides, it is easy to be erected
13) It has good softness
14) The signal quality is centered
15) It has good ability of preventing troubles and the signal is clear
16) It has become the most common wire used in CATV and other high-frequency conduct cable
17) It is a bimetallic wire with a copper cladding concentrically covering an aluminum core, integrating the beneficial properties of the wonderful conductivity of copper and the light-weight of aluminum
18) It can be scientifically processed into bare wire and flat wire, and it is the best material for coaxial cable, computer cable, telephone cable and shielding cable
19)The processing method is similar to that of copper wire during cable manufacture
