Do all electric machines use aluminum wire instead of copper wire now?
Because of the low melting point of aluminum, the main problem is the short time heat resistance of the equipment. For the motor equipment, the short-time heating is higher, so it is technically impossible to avoid
Welding problems. Copper welding is easier and more reliable, but aluminum welding is more troublesome and more problemsIf you see the same capacity, voltage and current equipment, the use of aluminum wire, and its shape with copper wire is almost large, may be market economy Jerry built products, even if the price is low, but also inadequate
The cross-sectional area of aluminum wire is lower than that of copper wire. Therefore, if the aluminum wire is to be used, its sectional area must be increased and the volume of the whole equipment will be increased
