Aluminum wire refers to the coiled wire products obtained by drawing aluminum and aluminum alloy wire blanks as raw materials. According to the material, it is divided into pure aluminum wire and alloy aluminum wire. According to the use, it is divided into industrial aluminum wire and process aluminum wire. It can also be divided into high-purity aluminum wire, ordinary aluminum wire and alloy aluminum wire. The aluminum content of high-purity aluminum wire is more than 99.9%, which is used in the electronic industry, vacuum coating, aluminized paper, etc. The aluminum content of ordinary aluminum wire is below 99.9%. It is used in the manufacture of wires, cables, motors, electrical appliances and as rivets and welding materials. Aluminum alloy wires are generally used in the electronics industry, textile industry, and as wires, cables, rivets, solders, etc.

Advantages of aluminum wire

(1) The price is cheap: the copper rod is 3.5 times the price of the aluminum rod, and the proportion of copper is 3.3 times that of the aluminum, so the aluminum wire cable is much cheaper than the copper wire cable, which is suitable for low-capital projects or temporary electricity.

(2) The cable is very light: the weight of the aluminum wire cable is 40% of that of the copper wire cable, and the construction and transportation costs are low.

(3) Anti-oxidation and corrosion resistance: aluminum reacts with oxygen in the air to quickly form an oxide film, which can prevent further oxidation, so aluminum wire is a must-have material for high-voltage, large-section, long-span overhead power transmission.
