China professional manufacture 99.9% Pure Copper Sheet C12000 C11000 C12200 Red Copper Sheet Plate for Industry

1.The difference in appearance and color of copper plate and brass plate When we observe the copper plate and the brass plate, we will find that the color of the brass plate is generally golden yellow and relatively shiny, but the color of the copper plate is rose red, which is also shiny. The red copper is also called red copper, that is, pure copper. Red copper and brass are different in color and quality! In fact, the color is clear at a glance. The surface of the red copper plate is oxidized, and there is a layer of red cuprous oxide, which looks purple-red. The quality of red copper is harder than brass, and the weight is about the same! So we can distinguish them from their appearance and color.
2.The difference in ingredients The composition of the copper plate is mainly copper, and the content of copper can be as high as 99.9%, but the composition of the brass plate is copper and zinc, about 60% copper, about 40% zinc, and individual grades contain about 1% lead. We can also distinguish them very well.
3.The difference in strength The strength of the copper plate and the brass plate are 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, but the composition of the copper plate is mainly copper, basically no Other impurities, so the strength of the copper plate is relatively low.
4.The difference in density The density of the brass plate is 8.52-8.62, and the density of the red copper plate is 8.9-8.95. Therefore, the density of the red copper plate and the brass plate is relatively large, and the density of the brass plate is smaller. The use of brass plates is extremely wide. With the increase in zinc content from H63 to H59, they can withstand thermal processing well, 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. Red copper is malleable, so it is often used in the electrical industry.
