What is the difference between copper plate and brass plate? 1. The difference in the appearance color of the copper plate and the brass plate. We observe that the color of the copper plate and the brass plate is generally golden yellow, which is relatively shiny, but the color of the copper plate is Rose Red, it is also shiny, copper is also called red copper, that is, pure copper, red copper and brass are different in color and quality! In fact, the color can be understood at a glance, the surface of the copper plate is oxidized, and there is a layer of red cuprous oxide, which looks purplish red. The quality of red copper is harder than brass, and the weight is almost the same! So we can also distinguish from their appearance and color. 2. The difference in composition the composition of the copper plate is mainly copper, and the copper content can be as high as 99. 9%, but the composition of brass plate is copper and zinc, copper is about 60%, zinc is about 40%, and some brands contain lead is about 1%, so we can also distinguish them from each other. 3, the difference in strength the strength of the copper plate and the brass plate is different, we can distinguish from the strength, the composition of the brass plate is more, so the strength of the brass plate is generally higher, however, the composition of the copper plate is mainly copper, and there are basically no other impurities, so the strength of the copper plate is relatively low. 4. The difference in density the density of brass plate is 8. 52-8. 62, the density of copper plate is 8. 9-8. 95, so the density of copper plate and brass plate is relatively large, and the density of brass plate is relatively small. Brass plates are widely used. With the increase of zinc content from H63 to H59, they can well withstand hot processing and are mostly used in various parts of machinery and electrical appliances, stamping parts and musical instruments. The copper plate has good electrical conductivity, thermal conductivity, corrosion resistance and toughness. Copper is malleable and is therefore commonly used in the electrical industry.
