At a glance: OD Ø20–Ø800 mm · Wall ≥5 mm · Length up to 1500 mm · Tolerance (as forged/machined) up to ±0.5 mm · UT/RT on request
Also available: titanium and steel forged hollows — see dedicated pages. This page focuses on forged aluminum tube hollows for thick-wall/large-diameter needs.
Manufacturing Routes for Thick-Wall & Large-Diameter Aluminum Tubes
Forged Hollows / Bored-from-Solid — preferred when sections are oversize or ultra-thick and higher structural integrity is required. The forged route delivers a dense microstructure and allows concentricity control via deep-hole boring; UT/RT is available on request.
Seamless / Drawn (comparison) — common route for mainstream OD/wall ranges with faster supply. For oversized sections or higher reliability requirements, Chalco recommends forged aluminum hollows (this page).
