What are the characteristics of tinned copper clad aluminum?

Learn about the characteristics of tinned copper clad aluminum:

1. DC resistivity: The DC resistivity of tinned copper clad aluminum is generally about 1.5 times that of pure copper wire. When the resistance value is the same, the weight is about 1/2 of that of pure copper wire. According to the "skin effect" calculation, at high frequencies above 5MHZ, the resistivity is the same as that of pure copper wire. Therefore, when it is used for digital cables and high-frequency signal cables, its electrical performance is the same as that of pure copper wires.

2. Compared with pure copper wire, copper clad aluminum wire is not valuable to a thief, because it is almost impossible to separate the pure copper coating from the aluminum core wire. Therefore, an additional anti-theft effect can be received.

3. The copper clad aluminum wire is light in weight and convenient for transportation and installation. Therefore, labor costs can also be reduced.

4. It is more malleable than copper wire and does not generate insulating oxides like aluminum, so it is easier to process. And better conductivity.

5. The product is processed by the international leading "cover welding drawing method" production process. Even in the strict twisting test, it will not appear detachment, cracking or peeling like electroplated products. No harm.
