Aluminum 7003 vs V95

Aluminum · grade comparison

Aluminum 7003 and V95 are both aluminum grades. V95 is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 315 MPa (45.7 ksi) for 7003, about 49% more; tensile strength follows at 545 MPa (79 ksi) vs 360 MPa (52.2 ksi). In exchange, 7003 is the more ductile: elongation 11% versus 8% for V95, and V95 is harder (150 HB vs 105 HB). 7003 conducts heat better (150 W/m·K vs 130 W/m·K). On the shop floor, V95 machines more easily (very good vs good), 7003 welds better (very good vs poor), and 7003 sits in a lower cost tier (standard, $$) than V95 (premium, $$$).

7003Choose it when the part is bent, formed or impact-loaded, or when it will be welded.

V95Choose it when strength drives the design, or when the part is machined in volume.
