The difference between fan copper wire and aluminum wire
The degree of reliability of solder joints, in fact, this is the main difference, aluminum coil easily oxidized in the welding time, welding point to false welding, resistance, heat, easy to solder joint desoldering, the used welding knows, will make people mad, and a failure, is to find out the false solder joints. The quality of instability caused by motor;
The melting point of aluminum is lower than that of copper, and the motor temperature is higher, so it is easy to burn the motorBecause the motor aluminum coil naturally low rate of finished products and copper coils, prone to failure in the process of using, replace the motor will generate additional costs and losses, the static electromechanical technology suggest that you choose copper exhaust fan motor.
The resistance of aluminum is larger than that of copper, and the heating will be great. But the exhaust fan power is not very large, but it is not a big problem,
