Aluminum 2014 vs A20X

Aluminum · grade comparison

Aluminum 2014 and A20X are both aluminum grades, both aerospace al. 2014 is the stronger of the two: yield strength 414 MPa (60 ksi) against 240 MPa (34.8 ksi) for A20X, about 73% more; tensile strength follows at 483 MPa (70.1 ksi) vs 380 MPa (55.1 ksi). 2014 is harder — 135 HB against 95 HB for A20X — which matters for wear surfaces and threads. A20X is stiffer (77 GPa vs 72.4 GPa) and 2014 conducts heat better (155 W/m·K vs 105 W/m·K). On the shop floor, A20X welds better (fair vs poor) and 2014 sits in a lower cost tier (premium, $$$) than A20X (specialty, $$$$$).

2014Choose it when strength drives the design, or when surface hardness matters.

A20XChoose it when it will be welded.

2014 vs A20X — frequently asked

Is 2014 stronger than A20X?

Yes. 2014 has a typical yield strength of 414 MPa (60 ksi) against 240 MPa (34.8 ksi) for A20X — about 73% more. Tensile strength is 483 MPa (70.1 ksi) vs 380 MPa (55.1 ksi).

Which is cheaper, 2014 or A20X?

2014 is the lower-cost material: it sits in the premium tier ($$$) while A20X is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which is easier to machine, 2014 or A20X?

2014, by a small margin. Both rate very good for machinability — 78/100 against 70/100 for A20X; for welding the order is A20X first (fair, 50/100) then 2014 (poor, 25/100).
