Aluminum 2030 vs 2098

Aluminum · grade comparison

Aluminum 2030 and 2098 are both aluminum grades. 2098 is the stronger of the two: yield strength 490 MPa (71.1 ksi) against 285 MPa (41.3 ksi) for 2030, about 72% more; tensile strength follows at 525 MPa (76.1 ksi) vs 400 MPa (58 ksi). In exchange, 2030 is the more ductile: elongation 12% versus 8% for 2098, and 2098 is harder (150 HB vs 100 HB). 2098 is lighter (2.7 g/cm³ vs 2.82 g/cm³ for 2030) and 2098 runs hotter in service (120°C vs 100°C continuous). On the shop floor, 2030 machines more easily (excellent vs good), 2098 welds better (poor vs not recommended), and 2030 sits in a lower cost tier (premium, $$$) than 2098 (high, $$$$).

2030Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

2098Choose it when strength drives the design, or when weight is the constraint.

2030 vs 2098 — frequently asked

Is 2098 stronger than 2030?

Yes. 2098 has a typical yield strength of 490 MPa (71.1 ksi) against 285 MPa (41.3 ksi) for 2030 — about 72% more. Tensile strength is 525 MPa (76.1 ksi) vs 400 MPa (58 ksi).

Which is cheaper, 2030 or 2098?

2030 is the lower-cost material: it sits in the premium tier ($$$) while 2098 is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which is easier to machine, 2030 or 2098?

2030. Its machinability rates excellent (92/100) against good (62/100) for 2098; for welding the order is 2098 first (poor, 25/100) then 2030 (not recommended, 12/100).
