What is Aluminium Wire?
Aluminium wire is a type of wire designed possessing a superior content of aluminium with other alloys. The versatile wires have good electrical and mechanical properties. The excellent thermal properties of these wires allow them to showcase excellent resistance properties across different systems. The wires of the aluminium grade have good tolerance to corrosive media due to tightly adhering inhibitors or antioxidants. Apart from this, the wires in this grade show outstanding electrical and heating resistance.
Where do you use Aluminum Welding Wire?
Aluminium welding wire is a type of soft metal that is lightweight and can be welded in place following conventional methods. Aluminium grade has a good affinity to oxygen, and it melts at temperatures of 1200 degrees F. The oxide layer protects the metal at temperatures of 3700 degrees F. As aluminium has a higher thermal conductivity, it showcases a small working window if it exceeds that then it and can be easily burnt out.
Why is Aluminium Alloy Wire used instead of copper for overhead cables?
Copper and aluminium alloys have been used as electrical conductors in electrical cables due to their excellent conductivity and low resistance. Copper is a better conductor and conducts electricity better than aluminium. But aluminium is still used in some applications as
