The 5\/16 inch 6061 aluminum round bar and its metric equivalents carry torque and shear loads in small drives, leave enough material for external threads, cross-holes, and rolled or turned flats, and still run fast on Swiss-type lathes, CNC turning centers, and bench machines. In the T6 temper the rod stays rigid under side load, resists the corrosion that attacks uncoated steel in damp or outdoor equipment, and anodizes cleanly when the part is visible.

It welds by MIG or TIG with 6061 or 4043 filler, keeping in mind that welding locally lowers T6 strength near the weld zone. Its corrosion resistance makes this 7–12mm aluminum bar stock suitable for outdoor mechanisms, marine-adjacent gear, and food-adjacent equipment where bare steel would rust, and it finishes by brushing, polishing, powder coating, or clear and colored anodizing with even results.\u003c\/p\u003e\n\u003cp class=\"rk-sub\"\u003eOrdering \u0026amp; Cut Length\u003c\/p\u003e\n\u003cp class=\"rk-p\"\u003eChoose any diameter from 7mm to 12mm, or the 5\/16 inch fractional size, then enter the straight length you need.
