DIN CuZn10 Common Brass Seamless Tubes Good Material For Hot Water Supply Pipeline
1. Description
The material of DIN CuZn10 brass tube is very hard, not easy to corrode, high temperature and high pressure resistance. It can be used in many environments. Compared with it, the disadvantages of many other materials are obvious. For example, the galvanized steel pipes used in some old residential buildings are very easy to rust. People will find that the tap water turns yellow, the water quality deteriorates and the water flow becomes smaller. The melting point of DIN CuZn10 brass is as high as 1083 ℃. For this kind of brass tube, the temperature used in general can be ignored. Archaeologists found a brass water pipe 4500 years ago in the pyramids of Egypt, which is still usable today. It can be seen that the use of brass tube is very long.
