Aluminum 6005A vs 6016

Aluminum · grade comparison

Aluminum 6005A and 6016 are both aluminum grades. 6005A is the stronger of the two: yield strength 235 MPa (34.1 ksi) against 115 MPa (16.7 ksi) for 6016, about 104% more; tensile strength follows at 275 MPa (39.9 ksi) vs 225 MPa (32.6 ksi). In exchange, 6016 is the more ductile: elongation 27% versus 11% for 6005A, and 6005A is harder (95 HB vs 60 HB). 6005A runs hotter in service (150°C vs 100°C continuous) and 6005A conducts electricity better (49 % IACS vs 43 % IACS). On the shop floor, 6005A welds better (excellent vs very good) and 6005A sits in a lower cost tier (budget, $) than 6016 (standard, $$).

6005AChoose it when strength drives the design, or when the part sees heat.

6016Choose it when the part is bent, formed or impact-loaded.
