Aluminum 6005A vs 6013

Aluminum · grade comparison

Aluminum 6005A and 6013 are both aluminum grades. 6013 is the stronger of the two: yield strength 365 MPa (52.9 ksi) against 235 MPa (34.1 ksi) for 6005A, about 55% more; tensile strength follows at 400 MPa (58 ksi) vs 275 MPa (39.9 ksi). 6013 is harder — 128 HB against 95 HB for 6005A — which matters for wear surfaces and threads. 6005A conducts heat better (190 W/m·K vs 150 W/m·K). On the shop floor, 6013 machines more easily (very good vs good), 6005A welds better (excellent vs good), and 6005A sits in a lower cost tier (budget, $) than 6013 (standard, $$).

6005AChoose it when it will be welded, or when cost is the deciding factor.

6013Choose it when strength drives the design, or when surface hardness matters.
