What is the difference between aluminum wire and copper wire

What is the difference between aluminum wire and copper wire

1. The color is different: 

-The color of copper wire is generally yellow to red, or purplish red. 

-The color of aluminum wire is gray white.

2. Different flexibility: 

Copper wire has better flexibility. This kind of wire has good fatigue resistance, good ductility and convenient bending. 

The flexibility of aluminum wire is poor. This kind of wire cannot be bent at will, otherwise the wire is easy to be broken.

3. Different conductivity: 

-The conductivity of copper wire is better than that of aluminum wire. 

-The resistance of copper core wire is smaller than that of aluminum core wire, so the power loss rate of aluminum core wire is large. 

-The load power of copper core wire and aluminum core wire with the same cross section will be greater than that of aluminum core wire.

4. Different stability: 

Copper core wires have good stability and are not prone to oxidation. Aluminum core wires have poor stability and are easy to oxidize.

5. Weight difference: 

Copper wire is heavier than aluminum wire because the density of copper wire is higher. 

The density of copper is 8.3 g/cm3, and that of aluminum is 2.7 g/cm3.

6. Price difference: 

The price of copper wire will be higher than that of aluminum wire, because the price of copper wire will be higher than that of aluminum wire. 

Under normal circumstances, the price of copper wire is about 3.5 times that of aluminum wire.
