BT5 Titanium Alloy is often used as a GOST Latin-style name, while VT5 Titanium Alloy is commonly used as the English transliteration of the Russian grade ВТ5 Titanium Alloy.
BT5-1 Titanium Alloy and VT5-1 Titanium Alloy refer to the Russian grade ВТ5-1 Titanium Alloy. Both naming styles may appear in technical enquiries, product searches and older material references. For supply, the final grade should always be verified by Russian grade name, chemical composition, MTC and project specification.
Russian BT5 / VT5 / ВТ5 should not be confused with ASTM Titanium Grade 5 / Ti-6Al-4V unless the material certificate confirms the exact chemistry and standard. VT5 / ВТ5 is a Russian titanium grade with its own composition and specification route, while ASTM Grade 5 is commonly known as Ti-6Al-4V.

Titanium is the base element in VT5 / ВТ5 and VT5-1 / ВТ5-1. It provides low density, corrosion resistance and a strong foundation for titanium alloy performance.
Aluminium increases strength, elastic modulus, heat resistance and specific strength in titanium alloys. It is the main alloying element in both VT5 and VT5-1.
Tin helps improve technological properties, oxidation resistance and creep resistance in VT5-1 titanium alloy. It also supports the Ti-Al-Sn alloy system used in medium-strength titanium applications.
Vanadium is controlled in these Russian titanium alloys and supports mechanical performance where present within the grade limit.
Molybdenum is controlled in VT5 composition and supports alloy strengthening, stability and mechanical performance.
| Controlled Element | Importance |

Tensile strength is important for VT5 and VT5-1 titanium alloys because it shows how much load the material can carry before fracture. This matters for sheets, plates, bars, rods, forgings, welded assemblies and stamped parts.
Elongation and ductility help determine how the alloy performs during forming, stamping, welding, machining and service. VT5-1 offers useful ductility in sheet, bar and plate forms, while VT5 supports welded and machined titanium components.
Hardness values are useful for machining control, finished product performance and inspection. VT5 / ВТ5 is listed with Brinell hardness around HB 229–321, while VT5-1 / ВТ5-1 is listed around HB 241–321.
VT5 / ВТ5 has listed density around 4400 kg/m³, while VT5-1 / ВТ5-1 has listed density around 4425 kg/m³. This low density helps reduce weight compared with many steel alloys.
VT5 / ВТ5 is commonly used for long service up to around +400°C, depending on product form, heat treatment and service conditions.
VT5-1 / ВТ5-1 is used for applications up to around +450°C, depending on material condition, component design and project requirement.
VT5 / ВТ5 and selected low-impurity VT5-1 / ВТ5-1 variants may be used in low-temperature or cryogenic applications where titanium’s strength-to-weight ratio and corrosion resistance are required. Final suitability should be confirmed through specification, MTC and service design.
Titanium’s natural corrosion resistance makes VT5 / ВТ5 and VT5-1 / ВТ5-1 suitable for aerospace, industrial, marine, chemical, fabricated and welded environments.
VT5 / ВТ5 and VT5-1 / ВТ5-1 are listed with weldability without restrictions in referenced material data. This makes them useful for welded parts, welded assemblies, fabricated components and aircraft internal structures.
VT5 and VT5-1 can be processed through cutting, turning, milling, drilling, grinding, CNC machining, rolling, forging, stamping and forming. Proper titanium tooling, coolant and temperature control are recommended.
VT5-1 is commonly described as not thermally hardened, so material condition is usually controlled through processing, annealing and product form rather than conventional hardening response.
