Aluminum 6060 vs 6101

Aluminum · grade comparison

Aluminum 6060 and 6101 are both aluminum grades. 6101 is the stronger of the two: yield strength 195 MPa (28.3 ksi) against 170 MPa (24.7 ksi) for 6060, about 15% more. 6101 is the more ductile: elongation 15% versus 12% for 6060, and 6060 is harder (75 HB vs 71 HB). On the shop floor, 6060 sits in a lower cost tier (budget, $) than 6101 (standard, $$).

6060Choose it when cost is the deciding factor.

6101Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
