All technology indexes of our leading product CCA have reached the national electronic
industry standard (SJ/T11223-2000) and American ASTM B566-93 standard. Its
copper layer takes refined copper above 99.97% purity under the cladding welding
& drawing method, cladding the plashing copper belt coaxially on the aluminum
house main, undergoing many times of drawing and heat treatment, have achieved the
need of customers' wire size demand and the technology demand of mechanics and
electrics. There forms a stable metallurgy combination between copper layer and
aluminum stick heart yarn, and copper layer distributes equality towards the circumferential
and portrait direction with good concentricity. It can make the different
metal materials become an inseparatable unity, which can be drayed like
a single metal, but the ratio between copper and aluminum will change while drawing,
but the copper layer volume is relatively stable, with smoothly and round
surface, without any defect
Carrying many characteristics of good conductivity, high strength and strong brazability
of copper and low density and easily to process of aluminum, CCA has its
own features of density equality of copper layer, high compactness and fine enlonging
capacity. This bimetal compound lead can be used into the coaxial cable conductor
with high signal transmitted features, and become the widely-used lead
in CATV and other high frequency appliances. CCA is also the best choice materials
for the coaxial cable conductor and cable wire of many electric equipments.
CCA Features:1. DR Resistively: CCA resistively is 1.5 times that that of pure copper wire. CCA
weight is about 1.2 times than pure copper wire on the same resistively. According
to the skin effect, its resistively is the same with pure copper wire while
above the 5 MHZ. So CCA electric capacity is as well as pure copper wire while
is used in digital cable and signal cable with high frequency.
2. Compared with pure copper wire, CCA has no value for larceners, because it become
impossible to depart the pure copper cladding layer from aluminum heart yarn,
so it has special function of anti-burglary.
3. With light weight, CAA is easy to transmit and fixed, on the other hand it can
reduce labor cost.
4. CCA has better plasticity than copper wire, and it will never produce insulated
oxide like aluminum, so it is easy to tackle with better conductivity.
5. Our products takes the international leading craftwork of cladding welding & drawing
method, so even in the strict wringing test, it will never take off, craze
or flake, having no harm to human health and environment.
Capacity comparisons between CCA and other products: Compared with pure copper conducting wire: CCA has many advantages of good conductivity,
light weight, available economical effects, softness and easy operation
in construction. Length ratio between CCA and pure copper wire is 2.45:1 under the
same wire size and weight, so buying 1 ton CCA is equal to buying 2.45 tons'
pure copper wire, having great advantages of saving production cost.
Compared with pure aluminum wire, CCA has a higher conductivity with enhanced
tensile strength, elongation percentage and fine brazability, for its surface
is cladded coaxially with a layer of pure copper, so it has good brazability as
well as copper and its mechanics and appliance capacity have improved greatly.
