Titanium BT5 Annealed vs BT5-VT5L
Titanium · BT5 temper comparison
BT5 Annealed and BT5-VT5L are two conditions of the same titanium grade, BT5: Annealed versus VT5L (cast version (ВТ5Л), annealed). The chemistry is identical, so every difference below comes from the condition. BT5 Annealed is the stronger of the two: yield strength 740 MPa (107 ksi) against 620 MPa (89.9 ksi) for BT5-VT5L, about 19% more; tensile strength follows at 830 MPa (120 ksi) vs 700 MPa (102 ksi). BT5 Annealed is the more ductile: elongation 13% versus 7% for BT5-VT5L, and BT5 Annealed is harder (265 HB vs 250 HB).
BT5 AnnealedChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
BT5 Annealed vs BT5-VT5L: 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.
