Small-diameter precision aluminum tube — also ordered as aluminum pipe — is our core product: 6061-T6, 6063-T5 and 3003-H14 in OD Ø6–Ø75 mm with 0.5–5.0 mm wall, tensile strength 150–310 MPa, produced and accepted to GB/T 6893, ASTM B234 and EN 754. Round ends and uniform wall suit heat exchangers, HVAC, automotive frames, furniture, scaffolding and general engineering; cut to drawing with end machining available. Stock and cut-to-size tube starts from a single length, regular stock ships in 3–7 days, and dimensional tolerance is held to the ordered standard (concentricity and wall tolerance can be tightened on request).
