1060/5052 Aluminum Discs Circles Round Sheet Plate Dia 50mm-300mm Thick 0.3-8mm

1060 is a commercially pure aluminum (99.6% Al) known for excellent formability, soft temper, and high electrical conductivity — ideal for spinning, deep drawing, and applications where easy shaping matters most. 5052 is an Al-Mg alloy with roughly 30–40% higher tensile strength and significantly better corrosion resistance, making it the better choice for structural parts, marine environments, or anywhere the disc will face mechanical stress or prolonged moisture exposure.

Measure the finished diameter you need and add material for any edge trimming or spinning reduction. For spinning blanks, a common rule is to start with a disc diameter approximately 2–2.5× the finished bowl or cup diameter. For flat gaskets or shims, match the disc diameter to your flange or bore OD. If you are unsure, order a 1-piece sample in the closest size and verify fit before committing to a larger quantity.

For most small electronics heat-sink bases (under 100 W), a thickness of 2–3 mm in 1060 alloy provides adequate thermal mass and is easy to drill and tap. For higher-power applications or where flatness under clamping load matters, 5 mm or 8 mm in 5052 alloy offers better rigidity. Always verify your thermal and mechanical requirements against the alloy datasheet before finalizing thickness.

Yes. Both 1060 and 5052 aluminum accept anodizing well. 1060 produces a clear, consistent anodic layer suitable for decorative and protective finishes. 5052 anodizes to a slightly darker tone due to its Mg content but achieves excellent corrosion protection. Powder coating is also compatible after standard degreasing and pre-treatment. Note that any post-processing will add to the final dimensions, so account for coating thickness in tight-tolerance applications.

Yes. Both alloys are weldable using TIG or MIG processes with the appropriate filler rod — ER1100 for 1060 and ER5356 or ER5183 for 5052. Clean the surface with acetone and a stainless steel brush before welding to remove the oxide layer. 5052 is generally preferred for welded assemblies because it retains more strength in the heat-affected zone compared to 1060.

For initial prototyping or fit-checking, the 1-piece option lets you verify dimensions and alloy behavior before committing. For small-batch production (under 20 parts), the 3- or 5-piece packs reduce per-unit cost. For larger runs, contact us to confirm bulk pricing and lead times, as requirements vary by size and alloy combination.

Use a digital caliper to measure diameter at two perpendicular axes and thickness at the center and near the edge. Standard mill-finish aluminum discs typically hold diameter within ±0.5 mm and thickness within ±0.1 mm for thinner gauges and ±0.2 mm for thicker stock. If measurements fall outside these ranges, contact us with photos and measurements for resolution.
