What is the difference between bare copper wire, tinned copper wire and copper clad aluminum wire?

How to identify copper clad aluminum and copper wire?

Generally, bare copper wire is made of pure copper, and tinned copper wire is coated with tin by hot tinning process on the basis of bare copper wire. The difference between the two can be clearly judged from the color.

As for the copper clad aluminum wire, the weight can be compared with that of the copper wire. The difference is very obvious. If there is an instrument, the resistance of the fixed length detected will be very obvious. The simplest way is to look at the section. The copper clad aluminum wire core is white, while the bare copper wire is the true color of the copper.

Comparison of the conductivity of the three: bare copper has the highest conductivity, followed by tinned copper wire, and copper clad aluminum wire is the worst.
