7/8 Inch 6061-T6 Aluminum Round Bar, 13–25mm Solid Bar
This is the general-purpose core of the RapidKeen bar range: 7/8 inch 6061 aluminum round bar and its matching metric sizes from 13mm to 25mm, all heat treated to the T6 temper. This is the workhorse band for CNC machining — large enough for real shafts, bushings, flanges, and fixtures, still fast and economical to turn and mill.
Every length is true solid 6061 aluminum rod — never tube — cut to straight lengths and ready for turning, boring, threading, milling, and fabrication. Choose the diameter that matches your drawing and order stock lengths or custom-cut aluminum bar stock from RapidKeen.
The best-selling fractional sizes in this band have dedicated pages: 5/8 inch, 3/4 inch, and 1 inch 6061-T6 aluminum round bar.
Why This Is the Workhorse Range
Most everyday machined aluminum parts live between 13mm and 25mm. In this band, 7/8 inch 6061 aluminum round bar and its metric neighbors give a designer enough stock to turn steps and shoulders, bore clean holes, mill keyways and flats, and cut real external threads — without wasting material or burning cycle time on oversized bar. The T6 temper keeps the finished part rigid and fatigue-resistant in rotating and pivoting service, while 6061 remains easy to weld, corrosion-resistant outdoors and on the water, and clean to anodize. That balance is why this single range supplies the majority of turned and milled 6061 components in American job shops.
Common Applications
What This Range Is Used For
Machining, Welding & Finishing
Across 13–25mm, 6061-T6 removes material quickly with light, continuous chips, holds fine turned finishes, and supports boring, cross-drilling, keyway milling, and coarse threading in minimal setups. It welds by MIG or TIG with 6061 or 4043 filler — welding locally lowers T6 strength in the heat-affected zone, so loaded shafts are usually kept unwelded. This aluminum bar stock takes bead blasting, brushing, polishing, powder coating, and clear or colored anodizing with even, repeatable results, which lets one bar serve both hidden mechanical parts and visible anodized components.
Industries That Buy This Range
Ordering & Cut Length
Choose any diameter from 13mm to 25mm, or the 7/8 inch fractional size, then enter the length you need. This 6061 aluminum round bar ships as single cut pieces for one-off jobs, or in production quantities for recurring parts. Ordering stock lengths and sawing in-house suits high-mix shops; custom cut-to-length service suits shops that want material delivered close to finished size.
Quick Questions
Why is 7/8 inch the lead size here? 7/8 inch is the main fractional size in this band without its own standalone page, so it anchors the collection; 5/8, 3/4, and 1 inch each have dedicated pages.
Metric or inch — which should I order? Order exactly what the drawing calls out. Metric 13–25mm stock suits metric drawings and imported equipment; fractional sizes suit standard US hardware.
Is this solid bar? Yes. Every diameter is solid round 6061-T6 rod, never hollow tube or pipe.
Can it be anodized and welded? Yes — 6061-T6 anodizes evenly and welds with standard aluminum fillers.
In-stock, standard 7/8 inch 6061-T6 aluminum round bar and 13–25mm 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 the broadest mix of CNC shafts, bushings, flanges, and fixture parts, the 7/8 inch 6061 aluminum round bar collection across 13–25mm is the shop-floor workhorse — solid 6061-T6 stock cut to your length.
