Product Details

ASTM C28000 Common Brass Seamless Tubes For Cold or Hot Water Supply Pipe In Washroom

1. Description

ASTM C28000 brass has good mechanical properties, good formability in hot state, good deformability in cold state and good machinability. It is easy to weld and weld fiber and is corrosion resistant, but it is easy to produce corrosion cracking. In addition, this grade of brass is cheap and widely used as a common brass variety.

C28000 brass seamless pipe is usually suitable for hot and cold water supply system of toilet and shower. We can supply straight pipe and U-bend according to customer's requirement.
