Extruded Aluminium Round Tube in 6061, 6063 and 7075 for Manufacturer Supply

What this aluminium round tube is This aluminium round tube is extruded from billet rather than rolled from strip, so the wall is even all the way round and the bore stays concentric. Wall thickness spans 0.3 mm to 50 mm, and the aluminium round tube can be ordered in any wall inside that band. Aluminium content is at least 98.8 percent. Because the aluminium round tube is pushed through a die, the same section can be held over a long production run. Grades and tempers offered Three grades cover most enquiries: 6061 for structural work, 6063 where anodizing quality matters, and 7075 where strength comes first. Temper runs from T3 to T8. Tolerance is plus or minus one percent, and the aluminium round tube can be supplied mill finish or finished after extrusion. Where the extruded tube is used Extruded aluminium round tube turns up in automobile and ship fittings, aviation brackets, electrical appliance frames, agricultural equipment, electromechanical assemblies and household appliances such as refrigerators, air conditioners and washing machines. Decorators use the aluminium round tube for trim, edging, picture frames, wardrobe rails and stair nosing, where the mill or anodized surface is the finish. Frames, plant and material handling Machine builders weld the aluminium round tube into trolley, cart and dolly frames, stillage posts, hopper rims, chute rails, guard hoops and roller stands, and the same section is bent into the rim of a tote bin or the axle sleeve of a caster leg. Installers use the aluminium round tube for downpipe brackets, drainage runs, sprinkler drops, hose reels and compressor line supports, where a light section can be fixed with a single anchor and still carry the fitting it holds. Leisure and outdoor equipment Tennis and badminton net posts, volleyball uprights, cricket stumps, fishing rod blanks and trekking poles are all thin wall tubes, and the aluminium round tube supplies the same stiffness at a lower weight than an equivalent steel shaft would. Finishing and colour Surface treatment covers mill finish, anodizing, polishing and powder coating, and an anodized bath can be dyed silver, bronze, champagne, black or golden. Standards followed include GB/T 5237, EN12020-1.2, ASTM B85-96 and JIS H5302. If the aluminium round tube will be welded, finish it after welding; if it will be anodized in a colour, keep the weld off the visible face. Buyer questions Q: Is the aluminium round tube extruded or drawn? A: It is extruded, which suits long runs of one section. Q: Which series can be supplied? A: 1000 through 7000 series, with 6061, 6063 and 7075 the usual choices. Q: How is the aluminium round tube cut? A: Length is made to order, so the aluminium round tube arrives cut to your list, and the end can be left burr free for a press fit. Q: Can small quantities be tested? A: Send the section of aluminium round tube you want to trial and we will quote it. Manufacturer supply Send the section drawing, the grade, the wall and the length, and tell us how the aluminium round tube will be joined or finished. We produce the aluminium round tube to order rather than holding a fixed catalogue, and bending, decoiling, welding, punching and cutting are all offered before dispatch. The aluminium round tube is then quoted against your list.
