Aluminum wire can be divided into: pure aluminum wire, alloy aluminum wire, 1100 aluminum wire, 1070 aluminum wire, 1060 aluminum wire, 5050 aluminum wire, 5056 aluminum wire, the difference between copper wire and aluminum wire is that copper wire is expensive and durable, and Copper wire retains its value, has good conductivity and high mechanical strength. aluminum magnet wire price is cheap but has a relatively short service life. Light weight, good electrical conductivity, but low mechanical strength, easy to oxidize.
The current carrying capacity of 16 square meters of copper wire and 25 square meters of aluminum wire is the same, and both can drive a 24 KW machine, but 25 square meters of aluminum wire is more economical, and 16 square meters of copper wire has a longer service life.
Although copper wire and aluminum wire are commonly used supporting materials for decoration, there is still a difference between copper wire and aluminum wire.



1. Copper wire, also called brass wire, has good flexibility, is not easy to break when bending back and forth, and has strong fatigue resistance; aluminum wire is made of aluminum, which is silver-white, easy to break when bent, and is not as flexible as copper wire.
2. Copper wire has anti-oxidation and corrosion resistance properties; while aluminum wire is extremely easy to oxidize, which increases resistance, reduces wire load, and is prone to safety problems; it has better stability than copper wire.
3. The resistivity of copper wire is small, which is lower than 1.68 times of aluminum wire; the resistivity of aluminum wire is high, the power loss is high, and the heat is serious, which indirectly affects the utilization rate of electricity.
4. The price of copper wire is several times higher than that of aluminum magnet wire price, and the weight is much heavier than aluminum wire. The overall price has also increased.
