Whether you are a hobbyist building a custom speaker baffle, a fabricator cutting gasket blanks, or a maker prototyping a rotating fixture, you need a 6061 round aluminum sheet disc plate that arrives ready to work — flat, deburred, and sized to spec.\u003c\/p\u003e\n\u003cp\u003eThese discs are cut from 6061-T6 aluminum alloy sheet stock. Available in four diameters — 100 mm (≈3.94 in), 150 mm (≈5.91 in), 200 mm (≈7.87 in), and 300 mm (≈11.81 in) — and ten thickness options ranging from 1 mm to 10 mm (≈0.04 in to 0.39 in). Sold in packs of 1, 2, or 5 pieces depending on the variant selected.\u003c\/p\u003e\n\u003cp\u003eTypical applications include CNC turning and milling blanks for round aluminum disc projects, heat-sink base plates for electronics enclosures, decorative face plates and cover discs for furniture or cabinetry, and lightweight structural spacers in jig and fixture builds. The 6061 alloy's combination of machinability and corrosion resistance makes it a go-to choice for both indoor workshop use and light outdoor exposure.\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:\u003c\/strong\u003e Suitable for standard CNC lathes, milling machines, drill presses, and hand tools.
