Description
x2 Inch 6061-T6 Aluminum Round Bar, 26–50mm Solid Bar Stock
This collection covers 6061-T6 aluminum round bar 2 inch and the full medium-large band from 26mm to 50mm: solid, heat-treated bar for spindles, gear and pulley blanks, thick flanges, mold components, and heavy tooling. At these diameters the material becomes a block of machinable stock you build the part out of, not just a shaft you trim down.
Every length is true solid 6061 aluminum rod — never tube, never cast — cut to straight lengths and ready for heavy turning, boring, facing, and milling. Choose the diameter that matches your drawing and order stock lengths or custom-cut aluminum bar stock from RapidKeen.
Diameters26mm–50mm solid round, incl 1-1/4, 1-1/2, 1-3/4 & 2 inch
Alloy & Temper6061-T6, solution heat treated and artificially aged
FormSolid round bar / billet rod, never hollow tube or pipe
LengthStock lengths, sawn blanks, or cut to your custom length
Available Diameters in This Collection
- 1-1/4 inch (26–32mm) 6061-T6 round bar — heavy shafts, adapter bodies, and rigid couplings
- 1-1/2 inch (33–39mm) 6061-T6 round bar — pulley blanks, hubs, roller shafts, and fixture blocks
- 1-3/4 inch (40–45mm) 6061-T6 round bar — gear blanks, thick flanges, and mold components
- 2 inch (46–50mm) 6061-T6 aluminum round bar — the lead size: spindles, heavy flanges, and tooling blocks
Why Shops Buy Medium-Large 6061 Bar
From 26mm to 50mm, a 6061-T6 aluminum round bar carries serious rotating and static loads while still machining several times faster than steel of the same diameter. Designers specify this range when a part needs a bored center, a bolt-circle flange, a keyed hub, or a thick fixture body that must start from solid. The T6 temper keeps the finished component rigid and dimensionally stable in service, and 6061's corrosion resistance lets the same bar serve washdown, outdoor, and marine-adjacent equipment. Compared with buying near-net castings, solid 2 inch 6061 bar stock machines predictably, welds when the design requires, and anodizes into a clean finished surface.

What This Range Is Used For
- Drive spindles, heavy shafts, and large-diameter axles
- Gear blanks, pulley blanks, sprocket blanks, and rotor hubs
- Thick mounting flanges, bolt-circle bases, and adapter plates turned from round
- Mold and die components, cavity blanks, and mold-base inserts
- Conveyor rollers, feed rollers, and their center shafts
- Rigid and sleeve-type couplings, shaft connectors, and collar bodies
- Cylinder component blanks, piston-related parts, and valve internals
- Fixture plates turned from solid, tooling blocks, locators, and tombstone-style workholders
Machining, Welding & Finishing
At 26–50mm, 6061-T6 aluminum round bar is built for stock removal: facing, rough boring, stepped turning, keyway and pocket milling, and coarse external threads all run with light, continuous chips, which slashes cycle time versus steel. The large cross section supports deep bores, annular grooves, and bolt-circle patterns while keeping the part fixtured on solid material. It welds by MIG or TIG with 6061 or 4043 filler, with the usual local reduction of T6 strength near the weld. Finishing options include bead blasting, brushing, polishing, powder coating, and clear or colored anodizing, with even results across the larger surface area.

Ordering, Sawing & Cut Length
Choose any diameter from 26mm to 50mm, or the 1-1/4 through 2 inch fractional sizes, then enter the length you need. This 6061 aluminum round bar can be supplied as full stock lengths, sawn blanks close to finished size, or single cut pieces for repair work. Heavy sections are cut square and packed to protect the machined surface; single pieces and production quantities of aluminum bar stock are both available.
Quick Questions
Why is 2 inch the lead size? 2 inch is the most-ordered diameter in this band and the natural anchor for the collection; 1-1/4, 1-1/2, and 1-3/4 inch are all stocked within it.
2 inch or move up to 3 inch? Stay at 2 inch for standard spindles, flanges, and gear blanks; step up to the 51–76mm collection when bores, wall thickness, or bolt patterns demand more starting stock.
Is this bar or billet? It is solid extruded 6061-T6 round bar, which doubles as small billet stock for parts machined from solid.
Can it be supplied pre-sawn? Yes. Order sawn blanks at your rough length and finish them in-house, or request cut-to-length pieces.
Shipping & Lead Time
In-stock, standard 2 inch 6061-T6 aluminum round bar and 26–50mm solid bar are prepared and shipped within 1–5 business days.
Custom-cut or processed orders require extra time based on processing complexity; the exact lead time depends on the size and quantity ordered.
After shipment, delivery to US addresses typically takes 7–15 days, and a tracking number is provided as soon as the order leaves our warehouse.
For spindles, gear blanks, thick flanges, and tooling blocks, the 6061-T6 aluminum round bar 2 inch collection across 26–50mm supplies solid, clean-machining bar stock — sawn or cut to your length.
