Copper clad aluminum tinning wire takes the copper clad aluminum magnesium alloy wire as the inner conductor, and tins surface to become a new shielding material. Its electric and machinery capacity is between copper wire and aluminum magnesium alloy wire, combining the well conductivity of copper and light weight and good shielding capacity of aluminum magnesium alloy wire. Advantages: Compared with tinning copper wire, the weight rate between copper clad aluminum tinning wire and pure copper tinning wire is 1to 2.5. That is to say, with the same wire size and weight, its length is 2.5 times as the pure tinning wire, and it has the advantage of lower the cost and lighten the weight. Compared with aluminum magnesium alloy wire, Copper clad aluminum tinning wire is of great welding capacity as pure copper wire as the its heart yarn is covered with a layer of copper, unlike the aluminum magnesium alloy wire, which is hard to tackle with. Capacity characteristic: the same with the copper clad aluminum magnesium alloy wire. Appliance scale:0.10-0.25mm Usage: information cable shielding net, coaxial cable shielding net, and other use shielding kintting net.
