Titanium Grade Ti-Pd7B-A vs Grade Ti-Pd7B-AW
Titanium · Grade Ti-Pd7B temper comparison
Grade Ti-Pd7B-A and Grade Ti-Pd7B-AW are two conditions of the same titanium grade, Grade Ti-Pd7B: A (solution annealed) versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Grade Ti-Pd7B-AW is the stronger of the two: yield strength 400 MPa (58 ksi) against 380 MPa (55.1 ksi) for Grade Ti-Pd7B-A, about 5% more. In exchange, Grade Ti-Pd7B-A is the more ductile: elongation 18% versus 14% for Grade Ti-Pd7B-AW, and Grade Ti-Pd7B-AW is harder (165 HB vs 150 HB).
Grade Ti-Pd7B-AChoose it when the part is bent, formed or impact-loaded.
Grade Ti-Pd7B-AWChoose it when strength drives the design.
Grade Ti-Pd7B-A vs Grade Ti-Pd7B-AW: 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.
