Aluminum Round Tube / Pipe
Aluminum Round Tube / Pipe is lightweight, good appearance and is as strong as steel. It is made from both heat treatable and non-heat-treatable aluminum alloy, and mainly made from 6000 series alloy. It has excellent corrosion resistance, good workability and good machinability, which make aluminum tubing a highly regarded industrial metal.
