Al-Mg alloy wire together with the following advantages:

1. The proportion of Al-Mg alloy wire is 2.7, and the proportion of tinned copper wire is 8.9. The later is 3.3 times of the former, that is to say, the length of Al-Mg alloy wire is 3.3 times of the length of tinned copper wire with the same diameter and weight.

2. Material will be reduced significantly in manufacturing cables by using Al-Mg alloy wire, thus enterprises will receive both economic benefits and technologic progress.

3. In shielded cable, the material of aluminum avoids electrochemical corrosion fundamentally, thereby extending the life of the cable.
