1.The difference in definition: brass, by definition, is an alloy of copper and zinc, if it is only ordinary brass composed of these two components, but if it is composed of these two elements, it is a special brass. Copper is a purer copper, because the color of copper is purple-red, so copper is also called copper.
2. The difference in appearance color: We observe copper and brass and will find that the color of brass is generally golden yellow, more lustrous, but the copper color is rose red, and it is also shiny, so we can distinguish from their appearance color.
3. Differences: The composition of copper is mainly copper, and the amount of copper can be as high as 99.9%, but the components in brass are copper and zinc, and more special brass may have other magazines, so it can also be well distinguished from the composition.
4, The difference in strength: the strength of copper and brass is not the same, we can distinguish from the strength, the composition of brass is more, so the strength of brass is generally relatively high, but the composition of copper is mainly copper, but the main component of copper is copper, basically no impurities, so the strength of copper is relatively low.
5. Density difference: the density of brass is 8.52-8.62, and the density of copper is 8.9-8.95, so the density of copper and brass is relatively large, and the density of brass is small.
6. The difference in conductivity: Since copper and brass both contain copper, copper and brass can conduct electricity, but the components of copper and brass are also different, so the conductivity of copper and brass is not the same, the composition of brass is more so the conductivity is relatively low, the composition of copper is mainly copper, so the conductivity of copper is relatively low.
7. The difference between corrosion resistance and cutting performance: brass has slightly worse corrosion resistance but better cutting performance, and copper has better corrosion resistance but poor cutting performance.
