These aluminium flat bar strips are stocked in a wide range of thickness-by-width combinations (30–50 mm thick × 32–200 mm wide) at a fixed 500 mm length, so fabricators, hobbyists, and tradespeople can order exactly the profile they need without paying for off-cuts they won't use.\u003c\/p\u003e\n    \u003cp\u003eEach piece is cut from 6061-T6 aluminium alloy — a heat-treated, medium-to-high-strength grade with a tensile strength typically in the 260–310 MPa range. Thickness runs from 30 mm to 50 mm; width options span 32 mm up to 200 mm; all pieces are 500 mm (approximately 19.7 in) long. The alloy's balanced silicon-magnesium composition gives it good machinability, solid weldability with 4043 or 5356 filler, and a natural oxide layer that resists atmospheric corrosion.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include structural brackets and gussets in light engineering rigs, CNC-machined fixture plates and jig components, sliding door tracks and frame reinforcements in renovation work, and custom motor-mount or chassis rails for robotics and RC builds. The consistent 500 mm cut length suits bench-top work where a standard drop-saw or cold-saw can take over from there.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility note:\u003c\/strong\u003e 6061-T6 is compatible with standard aluminium MIG\/TIG welding processes and most CNC milling, drilling, and tapping operations.
