Aluminum 8006 vs Sintered 2014

Aluminum · grade comparison

Aluminum 8006 and Sintered 2014 are both aluminum grades. Sintered 2014 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 130 MPa (18.9 ksi) for 8006, about 92% more; tensile strength follows at 270 MPa (39.2 ksi) vs 155 MPa (22.5 ksi). In exchange, 8006 is the more ductile: elongation 10% versus 1.5% for Sintered 2014, and Sintered 2014 is harder (90 HB vs 45 HB). Sintered 2014 is lighter (2.55 g/cm³ vs 2.71 g/cm³ for 8006) and 8006 is stiffer (69 GPa vs 62 GPa). On the shop floor, Sintered 2014 machines more easily (very good vs fair), 8006 welds better (very good vs poor), and 8006 sits in a lower cost tier (budget, $) than Sintered 2014 (high, $$$$).

8006Choose it when the part is bent, formed or impact-loaded, or when it will be welded.

Sintered 2014Choose it when strength drives the design, or when weight is the constraint.
