Titanium Grade 2-AW vs Grade 2-CW
Titanium · Grade 2 temper comparison
Grade 2-AW and Grade 2-CW are two conditions of the same titanium grade, Grade 2: AW (as-welded deposit) versus CW (cold worked). The chemistry is identical, so every difference below comes from the condition. Grade 2-CW is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 370 MPa (53.7 ksi) for Grade 2-AW, about 49% more; tensile strength follows at 620 MPa (89.9 ksi) vs 450 MPa (65.3 ksi). In exchange, Grade 2-AW is the more ductile: elongation 18% versus 14% for Grade 2-CW, and Grade 2-CW is harder (210 HB vs 178 HB). Grade 2-AW runs hotter in service (300°C vs 250°C continuous). On the shop floor, Grade 2-AW welds better (excellent vs very good).
Grade 2-AWChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Grade 2-CWChoose it when strength drives the design.
Grade 2-AW vs Grade 2-CW: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all titanium 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.

Grade 2-AW vs Grade 2-CW — frequently asked
Is Grade 2-CW stronger than Grade 2-AW?
Yes. Grade 2-CW has a typical yield strength of 550 MPa (79.8 ksi) against 370 MPa (53.7 ksi) for Grade 2-AW — about 49% more. Tensile strength is 620 MPa (89.9 ksi) vs 450 MPa (65.3 ksi).
Which condition does FabDigit quote by default, AW or CW?
O is the default Grade 2 condition in the FabDigit quote flow (neither AW nor CW). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, Grade 2-AW or Grade 2-CW?
Grade 2-CW, by a small margin. Both rate fair for machinability — 48/100 against 40/100 for Grade 2-AW; for welding the order is Grade 2-AW first (excellent, 90/100) then Grade 2-CW (very good, 80/100).
