Copper Clad Aluminum Wire (CCA)
Copper Clad Aluminum Magnesium Wire (CCAM)
Copper clad aluminum wire (cca wire) is a bimetallic wire with a
copper cladding concentrically covering an aluminum core, which
combines the optimum properties of both metals in a single
composite material ideally suited for most electrical conductor
applications. The processing method of CCA wire is similar to that
of copper wire during cable manufacturing. We specialize in bare
CCA (Copper Clad Aluminum) wire and CCAM (Copper Clad Aluminum
Magnesium) wire, with mechanical characters to meet completely the
requirement of making stranded wires, and braiding by high speed
braiding machines. We make a wide range of sizes of wires as per
buyers’ requirement.
Manufacture standard:
SJ/T 11223-2000, ASTM B566:1993, Copper Clad Aluminum Wire
The wire is divided into two mechanical status: Annealed (A) and
Hard drawn (H),
Resistivity ≤0.033mm2/m, Elongation rate of not less than 10%.
Advantages of CCA wire (CCAW):
1. Light-weight: CCAW is about one-third of the weight of copper
wire of the same thickness. This is extremely advantageous for
reducing the weight of the coil
2. DC resistance: CCAW has about 1.5 times the DC resistance of
copper wire. Because it is three times as light as copper wire,
however, only one-half of the weight of copper wire is needed to
handle the same current
3. Soldering: Because the surface of the conductor of CCAW is clad
with copper, there is no need for special soldering as is the case
with aluminum wire. Soldering can be done in exactly the same way
as with copper wire.
Application:
Cable inner conductor for low voltage cables, cable braiding and
shielding for coaxial cables.
