Copper clad aluminum wire

We specialize in manufacturing and exporting CCA wire, CCS wire, CCAM wire, TCCS wire, TCCA wire, and TCCAM wire with different

All technology indexes of our leading product CCA have reached the national electronicindustry standard (SJ/T11223-2000) and American ASTM B566-93 standard. Itscopper layer takes refined copper above 99.97% purity under the cladding welding& drawing method, cladding the plashing copper belt coaxially on the aluminumhouse main, undergoing many times of drawing and heat treatment, have achieved theneed of customers' wire size demand and the technology demand of mechanics andelectrics. There forms a stable metallurgy combination between copper layer andaluminum stick heart yarn, and copper layer distributes equality towards the circumferentialand portrait direction with good concentricity. It can make the differentmetal materials become an inseparatable unity, which can be drayed likea single metal, but the ratio between copper and aluminum will change while drawing,but the copper layer volume is relatively stable, with smoothly and roundsurface, without any defect.Carrying many characteristics of good conductivity, high strength and strong brazabilityof copper and low density and easily to process of aluminum, CCA has itsown features of density equality of copper layer, high compactness and fine enlongingcapacity. This bimetal compound lead can be used into the coaxial cable conductorwith high signal transmitted features, and become the widely-used leadin CATV and other high frequency appliances. CCA is also the best choice materialsfor 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. CCAweight is about 1.2 times than pure copper wire on the same resistively. Accordingto the skin effect, its resistively is the same with pure copper wire whileabove the 5 MHZ. So CCA electric capacity is as well as pure copper wire whileis used in digital cable and signal cable with high frequency.2. Compared with pure copper wire, CCA has no value for larceners, because it becomeimpossible 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 canreduce labor cost.4. CCA has better plasticity than copper wire, and it will never produce insulatedoxide like aluminum, so it is easy to tackle with better conductivity.5. Our products takes the international leading craftwork of cladding welding & drawingmethod, so even in the strict wringing test, it will never take off, crazeor 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 operationin construction. Length ratio between CCA and pure copper wire is 2.45:1 under thesame 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 enhancedtensile strength, elongation percentage and fine brazability, for its surfaceis cladded coaxially with a layer of pure copper, so it has good brazability aswell as copper and its mechanics and appliance capacity have improved greatly.
