Aluminum 2030 vs 2224

Aluminum · grade comparison

Aluminum 2030 and 2224 are both aluminum grades. 2224 is the stronger of the two: yield strength 425 MPa (61.6 ksi) against 285 MPa (41.3 ksi) for 2030, about 49% more; tensile strength follows at 480 MPa (69.6 ksi) vs 400 MPa (58 ksi). In exchange, 2030 is the more ductile: elongation 12% versus 9% for 2224, and 2224 is harder (132 HB vs 100 HB). 2224 runs hotter in service (120°C vs 100°C continuous) and 2030 conducts heat better (134 W/m·K vs 120 W/m·K). On the shop floor, 2030 machines more easily (excellent vs very good) and 2030 sits in a lower cost tier (premium, $$$) than 2224 (high, $$$$).

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

2224Choose it when strength drives the design, or when the part sees heat.

2030 vs 2224 — frequently asked

Is 2224 stronger than 2030?

Yes. 2224 has a typical yield strength of 425 MPa (61.6 ksi) against 285 MPa (41.3 ksi) for 2030 — about 49% more. Tensile strength is 480 MPa (69.6 ksi) vs 400 MPa (58 ksi).

Which is cheaper, 2030 or 2224?

2030 is the lower-cost material: it sits in the premium tier ($$$) while 2224 is high ($$$$). 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 2224?

2030. Its machinability rates excellent (92/100) against very good (72/100) for 2224; for welding the order is 2224 first (poor, 20/100) then 2030 (not recommended, 12/100).
