Titanium VT20L-A vs VT20L-F
Titanium · VT20L temper comparison
VT20L-A and VT20L-F are two conditions of the same titanium grade, VT20L: A (solution annealed) versus F (as fabricated). The chemistry is identical, so every difference below comes from the condition. Both yield at about 835 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (solution annealed versus as fabricated). VT20L-A is the more ductile: elongation 6% versus 5% for VT20L-F. VT20L-A runs hotter in service (500°C vs 450°C continuous).
VT20L-AChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
VT20L-A vs VT20L-F: 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.

VT20L-A vs VT20L-F — frequently asked
What is the difference between VT20L-A and VT20L-F?
VT20L-A and VT20L-F are two conditions of the same titanium grade, VT20L: A (solution annealed) versus F (as fabricated). The chemistry is identical, so every difference below comes from the condition. Both yield at about 835 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (solution annealed versus as fabricated).
Which condition does FabDigit quote by default, A or F?
HIP+A is the default VT20L condition in the FabDigit quote flow (neither A nor F). 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.
When should I choose VT20L-A over VT20L-F?
Pick VT20L-A when the part is bent, formed or impact-loaded, or when the part sees heat.
