What Are the Advantages of Aluminum Wire?

Aluminum wire refers to its full length in the longitudinal direction, and the uniform cross-section refers to a metal wire-shaped material made of pure aluminum or aluminum alloy as raw material. So, what are the main reasons for its widespread use?


1. The advantages of aluminum wire


  • Cheap price: Copper poles are 3.5 times the price of aluminum poles, and the proportion of copper is 3.3 times that of aluminum. Therefore, aluminum wire cables are much cheaper than copper wire cables and are suitable for low-cost projects or temporary electricity use. At the same time, the cost of aluminum wire is much lower than that of copper.


  • The cable is very light: the weight of the aluminum wire cable is 40% of the ZD copper wire cable, and the construction and transportation costs are low.


  • Anti-oxidation and corrosion resistance: Aluminum quickly reacts with oxygen in the air to form an oxide film, which can prevent further oxidation. Therefore, aluminum wire is a necessary material for internal high voltage, large cross-section, and large-span overhead power transmission. But the advantages of being used as a low-voltage line no longer exist. You can check more details about casi wire.


  • The density of aluminum is much smaller than that of copper. The weight of the aluminum wire used for the same amount of electricity is much smaller. It is easier to erect the line, and the cost of the facilities for laying the line is also much smaller.


2. The wide application of aluminum wire in the electronics industry


What are the applications of aluminum wire in emerging industries such as electronics? As we all know, aluminum powder, aluminum pellets and other aluminum materials are mainly used as metal packaging materials in the form of thin plates and foils. Making cans, lids, bottles, barrels, and packaging foils has become a traditional industry that consumes aluminum products. Today, the aluminum printing industry for printing has bid farewell to "lead and fire" and entered the era of "light and electricity". The aluminum-based PS plate provides strong support for this change in the printing industry. In addition, aluminum wire lamps for electronic appliances are mainly used in various fields such as bus bars, overhead wires, conductors, electrical components, refrigerators, and cables. Aluminum foil for air conditioners has excellent deep-drawing performance, high strength, and good extensibility, reaching an advanced level.
