Aluminum 2007 vs 2A17

Aluminum · grade comparison

Aluminum 2007 and 2A17 are both aluminum grades. 2A17 is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 300 MPa (43.5 ksi) for 2007, about 7% more; tensile strength follows at 440 MPa (63.8 ksi) vs 390 MPa (56.6 ksi). In exchange, 2007 is the more ductile: elongation 10% versus 9% for 2A17. 2A17 runs hotter in service (250°C vs 120°C continuous) and 2A17 conducts electricity better (35 % IACS vs 30 % IACS). On the shop floor, 2007 machines more easily (excellent vs very good), 2A17 welds better (good vs poor), and 2007 sits in a lower cost tier (premium, $$$) than 2A17 (high, $$$$).

2007Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

2A17Choose it when strength drives the design, or when the part sees heat.
