6061 Round Aluminum Sheet Disc Plate 170X3mm DIY Model Craft Art Handmade Plate

6061 is a heat-treatable aluminum alloy containing magnesium and silicon as its primary alloying elements. It offers a practical combination of moderate strength, good corrosion resistance, and excellent machinability, making it one of the most widely used alloys for general fabrication, DIY projects, and light structural applications.

Yes. 6061 aluminum machines cleanly with standard HSS or carbide drill bits, hole saws, and CNC routers. Use cutting fluid or WD-40 to reduce heat buildup and extend tool life. A drill press or milling machine will give the cleanest results, but hand drilling is also feasible for non-precision work.

The disc ships with a mill finish — a clean but unpolished surface. For painting, a light scuff with 220-grit sandpaper followed by an aluminum-compatible primer is recommended. For anodizing, the surface should be degreased and may require a light etch depending on your anodizer's process requirements.

6061 aluminum naturally forms a thin oxide layer that provides good resistance to moisture and mild atmospheric exposure. For prolonged outdoor use or marine environments, applying an anodized coating, powder coat, or clear lacquer will significantly extend the surface life of the disc.

For a single prototype or one-off art piece, the 1 pcs option is the most cost-effective starting point. If you are running a small batch — for example, making 3–4 identical display bases — the 4 or 5 pcs pack offers better per-unit value. The 10 or 20 pcs packs are suited to workshop stock or repeated production runs where having spares on hand avoids project delays.

6061 aluminum welds well to other 6061 or 6063 aluminum parts using MIG or TIG processes with 4043 or 5356 filler wire. Welding aluminum to steel requires specialized techniques (such as friction welding or transition inserts) and is not recommended for standard workshop setups. For joining to steel, mechanical fasteners or structural adhesives are more practical alternatives.

Based on the density of 6061 aluminum (approximately 2.70 g/cm³) and the disc geometry (170 mm diameter, 3 mm thick), a single disc weighs approximately 185–195 g (6.5–6.9 oz). Actual weight may vary slightly depending on the exact temper and surface condition of the material.
