What this aluminum tube is
This aluminum tube is an extruded profile that is then cold drawn, so the wall thickness and the bore stay even along the whole length. Grade can be 6061, 7005, 7075 or another 6000 or 7000 series alloy, and the aluminum tube is normally supplied in T6 temper, with T3 to T8 available.
Where this aluminum tube is used
Buyers order this aluminum tube for industry, decoration, medical and agricultural work: frames and supports, railings, window and door profiles, equipment parts and display frames. Where the aluminum tube stays outdoors it is anodized or powder coated, and where it will be machined further it is supplied mill finished.
How this aluminum tube is extruded
An extruded tube is pushed from a heated billet through a die, then cold drawn to the final wall and cut to 1 m to 12 m or to a custom length. Because the aluminum tube is drawn after extrusion the section stays concentric, and the aluminum tube can then be bent, punched, decoiled or welded as your drawing requires. Hardness is rated hard and standard sizes follow EN, DIN, ASTM, JIS and GB/T.
How to choose this aluminum tube
Start with the grade, because 6061 welds and bends easily, 7005 gives more strength for structures and 7075 is chosen where the highest strength matters. Then fix the outside diameter and the wall together, because a thin wall in a large diameter deforms more easily than a small section. Finally agree the length and the finish, because the aluminium content of the aluminum tube is 96% or more, and the aluminum tube is quoted from the drawing you send.
What to confirm before you order this aluminum tube
Confirm the grade and temper, the outside diameter and wall, the length, the tolerance and the finish. Confirm as well whether the ends need threads, holes, slots or a welded joint, because those operations change the price and the lead time of the aluminum tube. Samples are available, ISO is held, and production is quoted at 22 to 30 days after the drawing is agreed.
