1. The appearance and color are different
When we observe pure copper and brass, we will find that the color of brass is generally golden yellow and relatively shiny. Pure copper is also called red copper, so the color is generally purple-red, and it is also shiny, so we can also distinguish it from their appearance color.
2. The ingredients are different
The most important component of pure copper is copper, and the content of copper can be as high as 99.6%, but in addition to copper and zinc, there are some special brass that may have other impurities, so from the composition, we can also be distinguished well.
3, the strength is different
The strength of pure copper and brass is different. We can distinguish in terms of strength. The composition of brass is relatively large, so the strength of brass is generally relatively high. However, the composition of pure copper is mainly copper, and there are basically no other impurities, so the strength of pure copper is relatively low.
4. Different density
The density of brass is 8.52-8.93g/cm³, the density of pure copper is 7.62-7.83g/cm³, so the density of pure copper and brass is relatively small, the density of brass is relatively big.
5. Different conductivity
The most valuable property of pure copper is its very good electrical conductivity, second only to silver among all metals. Therefore, brass is less conductive than pure copper.
