Principal products of our company-----copper cladding aluminum wire and copper cladding aluminum-magnesium alloy wire adopt advanced cladding welding technology to clad top-grade copper on the surface of aluminum stick or aluminum-magnesium stick forming firm metallurgy connection among atoms between copper layer and core wire. Drawing and quenching treatment can be carried out like single tinsel to combine two different metals together. Proportion of copper and aluminum will become lighter in the process of drawing, while volume ratio of copper layer does not change.

High frequency signal has characteristic of skin effect, therefore the copper cladding aluminum wire and copper cladding aluminum-magnesium alloy wire has same conductance with pure copper wire while transferring high frequency signal (more than 5MHz).
Advantages of copper cladding aluminum wire and copper cladding aluminum-magnesium alloy wire：
1.Special compound performance: copper cladding aluminum wire has conductance of copper and low density of aluminum, therefore its applicable range is wide.
2.Good ductibility and machinability: can be treated with drawing and quenching treatment like pure copper wire and it can also be processed into copper cladding aluminum enameled wire, as well as silver plating and tinning copper cladding aluminum wire.
3.Obvious economic benefit: density of copper cladding aluminum is only 37% to 40% of pure copper, its length is 2.45 to 2.65folds of pure copper with same weight and diameter; cost will be greatly lowered to produce cable making use of length or intensity of lead.
4.Obvious social benefit and environmental benefit: save a lot of copper resource; reduce weight of cable which is convenient for transportation and construction, lower intensity of work; there is no pollution for cladding welding technique.
