Aluminum 7003 vs V96
Aluminum · grade comparison
Aluminum 7003 and V96 are both aluminum grades. V96 is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 315 MPa (45.7 ksi) for 7003, about 97% more; tensile strength follows at 660 MPa (95.7 ksi) vs 360 MPa (52.2 ksi). In exchange, 7003 is the more ductile: elongation 11% versus 6% for V96, and V96 is harder (190 HB vs 105 HB). 7003 is lighter (2.78 g/cm³ vs 2.89 g/cm³ for V96) and 7003 conducts heat better (150 W/m·K vs 130 W/m·K). On the shop floor, 7003 welds better (very good vs poor) and 7003 sits in a lower cost tier (standard, $$) than V96 (high, $$$$).
7003Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
V96Choose it when strength drives the design.
7003 vs V96: 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.

7003 vs V96 — frequently asked
Is V96 stronger than 7003?
Yes. V96 has a typical yield strength of 620 MPa (89.9 ksi) against 315 MPa (45.7 ksi) for 7003 — about 97% more. Tensile strength is 660 MPa (95.7 ksi) vs 360 MPa (52.2 ksi).
Which is cheaper, 7003 or V96?
7003 is the lower-cost material: it sits in the standard tier ($$) while V96 is high ($$$$). 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, 7003 or V96?
V96. Its machinability rates very good (72/100) against good (65/100) for 7003; for welding the order is 7003 first (very good, 75/100) then V96 (poor, 15/100).
