Aluminum 2030 vs 2A16

Aluminum · grade comparison

Aluminum 2030 and 2A16 are both aluminum grades. 2030 is the stronger of the two: yield strength 285 MPa (41.3 ksi) against 265 MPa (38.4 ksi) for 2A16, about 8% more. 2030 is the more ductile: elongation 12% versus 10% for 2A16, and 2A16 is harder (110 HB vs 100 HB). 2A16 runs hotter in service (250°C vs 100°C continuous). On the shop floor, 2030 machines more easily (excellent vs very good) and 2A16 welds better (very good vs not recommended).

2030Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

2A16Choose it when the part sees heat, or when it will be welded.

2030 vs 2A16 — frequently asked

Is 2030 stronger than 2A16?

Yes. 2030 has a typical yield strength of 285 MPa (41.3 ksi) against 265 MPa (38.4 ksi) for 2A16 — about 8% more. Tensile strength is 400 MPa (58 ksi) vs 400 MPa (58 ksi).

Which is cheaper, 2030 or 2A16?

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 2A16?

2030. Its machinability rates excellent (92/100) against very good (70/100) for 2A16; for welding the order is 2A16 first (very good, 72/100) then 2030 (not recommended, 12/100).
