What's the color of the copper core section of the cable?

What's the color of the copper core section of the cable?

Answer:

Copper wire is not so pure, it should be yellow, after cutting, light problems should be pale, quite normal. Pure copper is red, but pure copper is softer and expensive.
Your cable is not pure copper. Some cable is used for copper, some oxygen copper, there are some copper clad aluminum alloy.......
Of course, the quality of pure copper is the best, non - pure copper can not be said to be false, as long as the line with the five lines of standards can be.
The common market cable materials are: 4 copper 4 iron, copper coated iron, copper clad steel, copper clad aluminum, copper.The price is different. Oxygen free copper is the most expensive.Silver white is a wire or aluminum wire. Is the copper coated iron or copper clad aluminum.
