【Distinguish between pure copper and copper-clad aluminum】The cutting surface of copper wire is dark red, and the cutting surface of copper-clad aluminum is dark red on the outside and white in the middle

Pure copper has a high melting point and is not easily deformed

Copper clad aluminum has a low melting point and is easy to deform
