CCA wire is being accepted widely by a lot of countries as the replacement of cooper wire because of its good performances.

Structures & Performances:
1) Diameter: 0.12 - 1.02mm
2) It is a kind of bimetallic wire with a copper strap concentrically cladding an aluminum core. Which integrating the beneficial properties of the wonderful conductivity of copper and the light-weight of aluminum
3) The processing method is similar to that of copper wire during cable manufacture

4) 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
5) It is normally divided into 10% and 15% two kinds according to volumetric scale of copper layer
6) It is divided into annealed state (A kind) and hard state (H kind)
7) The DC resistivity at temperature of 20° C is less than 0.02676Ω . Mm² /m
8) Its nominal density is 3.32g/cm³ - 3.63G/cm³ , it is 37 - 40% of pure copper wire

9) Under the same weight, its length is 2.5 - 2.7 times that of pure copper wire
10) Its surface is bright and smooth, no any defects
11) It can save a lot of copper resource
12) Its conductivity is good
13) It can reduce the production cost of the cable and it is convenient in construction
14) It has remarkable economic benefit, besides, it is easy to be erected
15) It has good softness
16) The signal quality is centered
17) It has good ability of preventing troubles and the signal is clear
