What this aluminium tube is
This aluminium tube is a cold drawn pipe supplied in round, oval, square or irregular section. Cold drawing follows extrusion, so the aluminium tube holds a wall from 0.2 mm to 20 mm more evenly than an extruded tube alone, and the aluminium tube is normally supplied in T3 to T8 temper.
Where this aluminium tube is used
Buyers order this aluminium tube for bike frames, tent poles, industry, decoration, medical and agricultural work. The aluminium tube is also used for railings, frames and display structures, and it can be mill finished, anodized or powder coated where the part stays outdoors.
How this aluminium tube is cold drawn
Billet is extruded and then drawn through a die to the final wall, which leaves a smooth bore and a hard surface. The aluminium tube is then cut to the drawn length, and the aluminium tube can be punched, bent, decoiled or welded as the drawing requires.
How to choose this aluminium tube
Start with the grade, because the lower series bend easily while 6000 and 7000 series give more strength where the aluminium tube carries load. Then fix the outside diameter and the wall together, and agree the finish and the length on the drawing.
What to confirm before you order this aluminium tube
Confirm the grade and temper, the outside diameter and wall, the length and the finish. Confirm as well whether the ends need threads, holes or a welded joint, because those operations change the price and the lead time of the aluminium tube. Samples are available, ISO is held, standards follow EN, DIN, ASTM, JIS and GB/T, and production is quoted at 46 to 60 days.
