Enameled copper wire
Copper wire be used as conductor for so long time, and in all kinds of electric productions.
Why it will be selected as the main material?
First and the  important point is the superior conductivity. Since 1913, it tend to be adopt in many areas. And as for the processing technology has be improved over time, it has higher IACS conductivity values.
Secondly, copper has better tensile strength, conductivity and expansion property. Compare with aluminium wire, copper wire could bear higher temperature, and its service life will be longer. If you need the wire to produce more power, choose copper wire.

Enameled aluminium wire
These year, aluminium wire become more and more popular all over the world. It must have certain advantages which copper wire can’t satisfied.
When you will choose aluminium wire as conductor?
Aluminium wire has about more than 60% conductivity of copper, but the weight only the 30% of copper. That shows same electrical resistance, a bare aluminium wire weight half as much as a bare copper wire.
Then, cheap is a main reason that choose aluminium wire instead of copper. Now, the qualified aluminium wire widely use in household wiring. And as a response, aluminium has been being developed to have more similar properties as copper.

No matter copper wire or aluminium wire, they have own advantages and disadvantages. According to your requires to choose the better one. And FUDA could provide  products to let you choose.
