6061 6063 anodized aluminum tube tubing poles

6061 6063 have a moderately strength but are heat treatable. They have good corrosion resistance although not quite that offered by the 5000 series. One characteristic that makes this series very useful is its ability to be easily extruded into a wide variety of shapes and lengths. The 6061 offers great strength and machinability aht 6063 but the latter has better extrudability.
