3/4 Inch 6061-T6 Aluminum Round Bar, Solid 19mm Rod Stock

3/4 Inch 6061-T6 Aluminum Round Bar, Solid 19mm Rod Stock

The 3/4 inch 6061-T6 aluminum round bar is one of the three best-selling diameters in the RapidKeen solid bar range. It is a solid 19mm-class aluminum rod, heat treated to the T6 temper, built for real shafting, bushing, and fitting work where a half-inch bar is not quite enough. From marine hardware to production CNC runs, this 6061 aluminum rod is the go-to size for medium-duty rotating and structural parts.

Every length of 3/4 inch aluminum bar stock is solid round stock — never tube — and arrives ready for turning, boring, threading, milling, and fabrication. Order by the foot, pick a standard stock length, or enter a custom cut length and the 6061 aluminum round bar shows up ready to fixture in your machine.

Why 3/4 Inch Is a Top-Selling Size

Three-quarter inch is the point where a 6061 rod becomes a serious load-carrying shaft. The 3/4 inch 6061-T6 aluminum round bar has enough cross section to stay stiff under rotating and cantilever loads, enough meat to bore clean holes, cut keyways, and form heavy external threads, and it still machines quickly without hogging tooling. Along with 1/2 inch and 1 inch, it is one of the diameters American shops reorder most, because 3/4 inch mounts, bosses, bushings, and pivot bores show up constantly in conveyors, pumps, trailers, marine fittings, and factory equipment.

What the T6 Temper Gives You

6061 is an aluminum-magnesium-silicon alloy. In the T6 temper it is solution heat treated and artificially aged, lifting its strength far above soft aluminum while keeping the weldability and corrosion resistance the alloy is known for. That makes this 19mm aluminum bar stock a solid choice for parts that must carry load outdoors, on the water, or around chemicals, and it anodizes to a smooth, even finish for visible marine and automotive components.

Common Applications

Parts Made From 3/4 Inch 6061 Rod

Machining, Welding & Finishing

3/4 inch 6061-T6 aluminum round bar turns, bores, and mills with light, continuous chips and a clean surface, and it taps and threads without built-up edge. The extra diameter leaves room to step the shaft down, bore a central hole, or machine a keyway in a single setup. It welds well by MIG or TIG with 6061 or 4043 filler — note that welding locally lowers T6 strength near the weld zone. For visible parts, this 6061 aluminum rod takes bead blasting, brushing, polishing, powder coating, and clear or colored anodizing with even, repeatable results.

Industries That Buy This Diameter

Ordering & Cut Length

Order this 3/4 inch 6061 aluminum rod by the foot, choose a 1–6 ft stock length, or enter a custom cut length to match your drawing. Every piece of 6061 aluminum round bar is cut square to length with a clean, dent-free surface. Buy a single piece for an axle repair or production quantities of 19mm aluminum bar stock for a recurring shaft — stocked diameters carry no forced bulk minimum.
