Why is there such a big difference in price for the same copper wire?

Brass, an alloy of copper and zinc, is also known as pure copper and red copper, where is the difference between the two? 1. Appearance: Purple copper has a layer of red cuprous oxide on the surface, so it is often purplish red or rose red, while brass is usually golden yellow. 2. Composition: The main component of brass is copper and the copper content is very high, but brass is mainly composed of copper and zinc, while special brass will also contain other substances. 3. Electrical conductivity: brass and copper contain copper so they can conduct electricity, but because brass has more other elements and the copper component of purple copper is better, so the performance of purple copper conductors is better than brass. 4. Density: brass density in 8.52-8.62, copper density in 8.9-8.95, so the density of purple copper than brass to be larger. 5. Corrosion resistance: brass < bronze 6. Cutting performance: brass > purple copper 7. Price: Copper is more expensive than brass 8. Use: Purple copper is commonly used in the wire and cable industry, while brass is mainly used for valves, water pipes, and radiators, etc.
