Designers specify it when a part needs deep concentric bores, wide bolt circles, thick walls, or a one-piece body that cannot tolerate welds or fastener joints — mold and die blocks, heavy housings, end caps, wheels, and mounting flanges. In the T6 temper the solid section stays rigid under clamp and service loads, and at roughly one third the density of steel it keeps machine tables, rotating assemblies, and finished equipment far lighter. Solid 6061-T6 billet also machines far more predictably than castings: no porosity surprises, consistent hardness from face to core, and a clean response to welding, anodizing, and other finishing.\u003c\/p\u003e\n\u003cp class=\"rk-sub\"\u003eRound Bars and Round Blanks (Discs \/ Slugs)\u003c\/p\u003e\n\u003cp class=\"rk-p\"\u003eThe same large diameter 6061 aluminum round bar can be supplied as long billet or sliced into round blanks — thick discs or slugs cut to your required thickness. Round blanks are the efficient starting shape for face-turned parts such as end caps and lid plates, wheel and pulley blanks, piston and gland discs, bearing retainers, flange plates, and round mold inserts. Sawing the discs before they reach your shop saves machine time and material handling, while full billet lengths suit shops that prefer to slice their own blanks.\u003c\/p\u003e\n\u003cp class=\"rk-sub\"\u003eCommon Applications\u003c\/p\u003e\n\u003cdiv class=\"rk-chips\"\u003e\n\u003cspan\u003eMold \u0026amp; die blocks\u003c\/span\u003e\u003cspan\u003eHeavy mounting flanges\u003c\/span\u003e\u003cspan\u003eRound blanks \u0026amp; discs\u003c\/span\u003e\u003cspan\u003eBillet housings\u003c\/span\u003e\u003cspan\u003eLarge gear blanks\u003c\/span\u003e\u003cspan\u003ePress \u0026amp; fixture tooling\u003c\/span\u003e\u003cspan\u003eBearing housings\u003c\/span\u003e\u003cspan\u003eEnd caps \u0026amp; lid plates\u003c\/span\u003e\u003cspan\u003eWheel \u0026amp; pulley blanks\u003c\/span\u003e\u003cspan\u003eHeavy-equipment parts\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cp class=\"rk-sub\"\u003eWhat This Range Is Used For\u003c\/p\u003e\n\u003cdiv class=\"rk-box\"\u003e\n\u003cul class=\"rk-list\"\u003e\n\u003cli\u003eMold and die blocks, cavity inserts, and mold-base components machined from solid\u003c\/li\u003e\n\u003cli\u003eHeavy mounting flanges, bolt-circle bases, and thick adapter plates\u003c\/li\u003e\n\u003cli\u003eSliced round blanks and discs for end caps, retainers, and cover plates\u003c\/li\u003e\n\u003cli\u003eBillet housings, body blocks, and enclosure components for pumps and machinery\u003c\/li\u003e\n\u003cli\u003eLarge gear, wheel, sheave, and pulley blanks with deep bores and keyways\u003c\/li\u003e\n\u003cli\u003ePress tooling, fixture bases, tombstone-style workholders, and locator blocks\u003c\/li\u003e\n\u003cli\u003eThick bearing housings, sleeve blocks, and cylinder component parts\u003c\/li\u003e\n\u003cli\u003eHeavy-equipment, marine, and structural parts that demand one-piece solid stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cp class=\"rk-sub\"\u003eMachining, Welding \u0026amp; Finishing\u003c\/p\u003e\n\u003cp class=\"rk-p\"\u003eLarge 6061-T6 aluminum round bar is built for aggressive stock removal: facing, deep boring, contoured turning, and wide pocket milling all cut with light, continuous chips, so a billet block reaches finished shape much faster than steel, with far less wear on tooling. The solid section supports concentric bores, dense bolt patterns, cross-holes, and annular grooves from minimal setups. It welds by MIG or TIG with 6061 or 4043 filler, noting the local reduction of T6 strength near the weld, and it finishes by bead blasting, brushing, polishing, powder coating, or clear and colored anodizing with even results across the large surface area.\u003c\/p\u003e\n\u003cp class=\"rk-sub\"\u003eIndustries That Buy This Range\u003c\/p\u003e\n\u003cdiv class=\"rk-chips\"\u003e\n\u003cspan\u003eMold \u0026amp; tool making\u003c\/span\u003e\u003cspan\u003eHeavy CNC machining\u003c\/span\u003e\u003cspan\u003ePumps \u0026amp; rotating equipment\u003c\/span\u003e\u003cspan\u003eHydraulics \u0026amp; fluid power\u003c\/span\u003e\u003cspan\u003ePress \u0026amp; forming equipment\u003c\/span\u003e\u003cspan\u003eMarine \u0026amp; heavy equipment\u003c\/span\u003e\u003cspan\u003eEnergy \u0026amp; industrial machinery\u003c\/span\u003e\u003cspan\u003eMaintenance \u0026amp; repair (MRO)\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cp class=\"rk-sub\"\u003eOrdering, Sawing \u0026amp; Cut Length\u003c\/p\u003e\n\u003cp class=\"rk-p\"\u003eChoose any diameter from 80mm to 100mm, then order full stock lengths, sawn billet blocks, or sliced round blanks at the thickness you need.
