Aluminum 2030 vs 2A10

Aluminum · grade comparison

Aluminum 2030 and 2A10 are both aluminum grades. 2030 is the stronger of the two: yield strength 285 MPa (41.3 ksi) against 245 MPa (35.5 ksi) for 2A10, about 16% more. In exchange, 2A10 is the more ductile: elongation 18% versus 12% for 2030. 2A10 runs hotter in service (120°C vs 100°C continuous). On the shop floor, 2030 machines more easily (excellent vs very good).

2030Choose it when strength drives the design, or when the part is machined in volume.

2A10Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

2030 vs 2A10 — frequently asked

Is 2030 stronger than 2A10?

Yes. 2030 has a typical yield strength of 285 MPa (41.3 ksi) against 245 MPa (35.5 ksi) for 2A10 — about 16% more. Tensile strength is 400 MPa (58 ksi) vs 390 MPa (56.6 ksi).

Which is cheaper, 2030 or 2A10?

Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, 2030 or 2A10?

2030. Its machinability rates excellent (92/100) against very good (70/100) for 2A10; for welding the order is 2A10 first (poor, 18/100) then 2030 (not recommended, 12/100).
