When we observe copper and brass, we will find that the color of brass is generally golden yellow and more lustrous, but the color of copper is rose red and also shiny, so we can also distinguish from their appearance color.

2. The composition is different

The composition of copper is mainly copper, and the copper content can be as high as 99.9%, but the composition of brass is copper and zinc, and more special brass may have other magazines, so we can also distinguish it well from the composition.

3. The intensity is different

The strength of copper and brass is different, 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, basically there are no other impurities, so the strength of copper is relatively low.

4. The density is different

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.
