Brass tubing is used to transfer liquids, air, or solids, and it is characterized by a round shape and a hollow center. The tubing is seamless for a smoother interior flow and greater burst strength than welded tubing. It is corrosion-resistant and provides greater hardness, can be used for pipeline, model making, model rail and boat, architectural design, engineering, school projects. Features: Made of brass, high hardness and good ductility, strong, quite sturdy and nicely shiny. Light weight, good thermal conductivity, especially good rust resistance and easy processing. Better withstand high pressure and high temperature, resist corrosion. It has good mechanical properties, good machinability, widely used and easy welding. Suitable for pipeline, model making, model rail and boat, architectural design, engineering, school projects.
