1, the difference in appearance and color. The color of brass plate is usually golden yellow, more shiny, but the color of purple copper plate is rose red, also shiny, purple copper is also called red copper, that is, pure copper, red copper and brass are different in color and quality.
2, the difference in composition. The composition of the purple copper plate is mainly copper, and the copper content can be as high as 99.9%, but the composition of the brass plate has copper and zinc, copper 60% or so, zinc 40% or so, individual grades containing lead 1% or so.
3, the difference in strength. Brass plate composition is more so the strength of brass plate is generally higher, but the composition of copper plate is mainly copper, basically no other impurities, so the strength of copper plate is relatively low.
4, the difference in density. The density of brass plate is in 8.52-8.62, the density of copper plate is in 8.9-8.95, so the density of copper and brass plate is relatively large, the density of brass plate is smaller.
