ASTM C26100 Common Brass Seamless Tubes For Heat Exchanger And Mechanical Pipes
1. Description
ASTM C26100 seamless brass tube has good formability (the best brass) and high strength. It has good machinability and is easy to weld. It is very stable to general corrosion. C26100 seamless copper tube is suitable for heat exchanger, paper tube and electronic parts.
Brass is an alloy of copper and zinc. Ordinary brass is made of copper and zinc. Special brass is made up of more than two kinds of elements. Such as lead, tin, manganese, nickel, lead, iron, silicon copper alloy and so on. Brass has strong wear resistance, high hardness and high chemical corrosion resistance. The mechanical properties of cutting are also very good. The seamless brass tube drawn by brass is soft and wear-resistant. Brass seamless pipe is generally used in heat exchanger and condenser, low temperature pipeline and submarine transportation pipeline.
