Copper Clad Aluminum Alloy wire

Model: CCAA
Diameter: 0.08mm~3mm
Capacity:300 tons/m
Standard: JBT 11867-2014

Copper Clad Aluminum Alloy wire (CCAA) is a kind of bimetallic wire by covering copper on the surface of aluminum alloy rod. CCAA has high tensile strength same as CCAM wire, and high conductivity same as CCA wire . CCAA wire can be processed same as pure copper wire.

Features:
Compared to Copper wire
1. Small density, light weight
2. No brittleness under low temperature, good creepage resistant

Compared to CCAM wire
1. Higher conductivity;
2. No electrochemical corrosion (oxidation).corrosion will lead to wire breaking

Compared to CCA wire
1.Higher tensile strength
2.Good flexibility
3.Good Solderability
