The difference between the motor coil of copper wire and aluminum coil

A variety of indicators of copper coil electrical conductivity, tensile strength,power loss rate are better than aluminum! The conductive properties of silvercoil is the best, but the price is too high. If you use the three kinds of materialsto do the motor of the same power, the minimum volume of silver coils and save electricity, copper coil next, finally is the aluminum coil. With the development of technology and the high price of copper. Aluminum and aluminum alloy application and prospect will be more and more broad.
