Aluminum Round Tubes are available in alloys 6061, 6063 Aluminum 6061 is the most widely used alloy, offering better corrosion resistance and weldability than other Aluminum Round Tube, but less strength. Alloy 6063 offers high corrosion resistance and is commonly used for outdoor structural applications such as Aluminum Tube railings and trims. Aluminum Round Tube 2024 is high-strength and commonly used in aerospace applications.
What's the difference between pipe and tube?
"Pipes are passageways. Tubes are structural."
A pipe is
generally measured by inside diameter or ID.
A Tube
, on the other hand, is measured by Outside Diameter.
