Aluminum ZL114A vs ZL301
Aluminum · grade comparison
Aluminum ZL114A and ZL301 are both aluminum grades. ZL114A is the stronger of the two: yield strength 275 MPa (39.9 ksi) against 110 MPa (16 ksi) for ZL301, about 150% more; tensile strength follows at 340 MPa (49.3 ksi) vs 160 MPa (23.2 ksi). ZL114A is the more ductile: elongation 5% versus 3% for ZL301, and ZL114A is harder (100 HB vs 55 HB). ZL301 is lighter (2.57 g/cm³ vs 2.67 g/cm³ for ZL114A) and ZL114A is stiffer (72 GPa vs 68 GPa). On the shop floor, ZL301 machines more easily (very good vs good) and ZL114A welds better (very good vs fair).
ZL114AChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
ZL301Choose it when weight is the constraint, or when the part is machined in volume.
ZL114A vs ZL301: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all aluminum grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

ZL114A vs ZL301 — frequently asked
Is ZL114A stronger than ZL301?
Yes. ZL114A has a typical yield strength of 275 MPa (39.9 ksi) against 110 MPa (16 ksi) for ZL301 — about 150% more. Tensile strength is 340 MPa (49.3 ksi) vs 160 MPa (23.2 ksi).
Which is cheaper, ZL114A or ZL301?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, ZL114A or ZL301?
ZL301. Its machinability rates very good (78/100) against good (55/100) for ZL114A; for welding the order is ZL114A first (very good, 75/100) then ZL301 (fair, 45/100).
