Aluminum 6060 vs 6063A

Aluminum · grade comparison

Aluminum 6060 and 6063A are both aluminum grades. 6063A is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 170 MPa (24.7 ksi) for 6060, about 21% more; tensile strength follows at 245 MPa (35.5 ksi) vs 215 MPa (31.2 ksi). In exchange, 6060 is the more ductile: elongation 12% versus 10% for 6063A, and 6063A is harder (80 HB vs 75 HB). On the shop floor, 6060 sits in a lower cost tier (budget, $) than 6063A (standard, $$).
