Aluminum 2011 Machining

Aluminum 2011 Machined Parts

Cox Manufacturing has a reputation for machining quality parts from Aluminum alloy 2011. We can machine intricate parts on our CNC Swiss machines and CNC turning centers.

Aluminum alloy 2011 has the highest machinability of all aluminum alloys, suitable for complex and detailed parts. Considered a free-machining alloy (FMA), it can be quickly machined to very close tolerances and produces an excellent surface finish. Aluminum 2011 is a great economical choice due to its machinability and production of fine, easily removable chips.

Aluminum 2011 is the standard for relative machinability compared to all other aluminum alloys. It has a machining cost factor of 0.6 when compared to steel 12L14. It can be forged or hot worked but is not ideal for welding or soldering. 2011 can be heat treated, annealed, aged, and tempered. It can be anodized but results in a darker and less corrosion resistant finish than Aluminum 6061.
