Aluminum 2017 vs MIC6

Aluminum · grade comparison

Aluminum 2017 and MIC6 are both aluminum grades. 2017 is the stronger of the two: yield strength 276 MPa (40 ksi) against 110 MPa (16 ksi) for MIC6, about 151% more; tensile strength follows at 427 MPa (61.9 ksi) vs 170 MPa (24.7 ksi). 2017 is the more ductile: elongation 22% versus 3% for MIC6, and 2017 is harder (105 HB vs 65 HB). MIC6 runs hotter in service (150°C vs 120°C continuous). On the shop floor, MIC6 machines more easily (excellent vs very good), MIC6 welds better (fair vs poor), and MIC6 sits in a lower cost tier (standard, $$) than 2017 (premium, $$$).

2017Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

MIC6Choose it when the part sees heat, or when the part is machined in volume.
