Advantages of copper clad aluminum wire:
1. Dc resistivity: the dc resistivity of the copper clad aluminum wire is about 1.5 times that of the pure copper wire, and the copper clad aluminum wire is about 1/2 the weight of the pure copper wire. According to the "skin effect" calculation, the resistivity is the same as the pure copper wire at the high frequency of 5MHZ.
2. Good weldability: copper clad aluminum wire has the same solderability as pure copper wire due to its concentric coating of pure copper.
3. Light weight: the proportion of copper clad aluminum wire is only 37% - 37% of pure copper wire, online diameter, under the condition of equal weight, the length is 2.5 times of pure copper wire, thus greatly reduces the production cost, buy 1 ton of copper clad aluminum wire is bought 2.5 tons of pure copper wire;
4. Copper clad aluminum wire has obvious advantages over pure copper wire: light weight, convenient transportation, soft and easy to process, saving copper resource consumption and low cost. The cost comparison between the copper clad aluminum wire and the pure copper wire:
The density of copper clad aluminum is 3.63g/cm3, the copper density is 8.89g/cm3, and the density ratio is 1:2.5, so the length of 1000kg copper clad aluminum magnesium alloy wire is equivalent to the length of the pure copper wire of 2500kg.
For example, the copper clad aluminum wire has a price of 72 yuan /kg. Pure copper bare wire is sold for 48.6 yuan /kg.
The cost of saving is about 48600 yuan (48600 yuan * 2.5 times - 72,000 yuan =48600 yuan) using 1000kg of copper clad aluminum wire and 2500kg pure copper wire.
Therefore, the use of copper clad aluminum wire instead of pure copper wire can greatly reduce the cost of raw materials.
