General characteristics
Titan brands VT6S, VT6 belong to the group α+β alloys. They are made according to GOST 19807−74, 90013−81 OST. Alloy VT6 legarrette 6% Al + 4,5% V, and alloy VT6S — 5% Al + 4%V. Aluminum is able to consolidate the α+β phase, the vanadium contributes to the stabilization of β-phase and impedes the formation of superstructure alpha-2 in α-phase… Aging and hardening increase the strength level by 15 — 20% while maintaining a fairly high plasticity. Option cast alloy ВТ6Л.

Basic properties
Marks WH, VT6 at his strength is not inferior to steel but lighter by almost half, are heat resistance, low thermal conductivity, easy stamped and forged. has a high specific strength, corrosion resistance, namagnichennosti. These alloys for corrosion resistance superior to stainless steel. Though their cost is quite high, since production is associated with large energy consumption, however the winning combination of qualities makes materials based on titanium no alternative material for modern industry.
Use
Titan brand VT6 is used in the manufacture of parts of aircraft engines (CPV casing, the stopper). He is responsible for the production of fasteners and parts of rockets. The alloy claimed in the manufacture of parts of household appliances, chemical machinery, sports equipment, structural elements that work in contact with sea or fresh water. Biological inertness makes it possible to produce from alloy VT6 implants for surgery. Heat resistance is important when manufacturing shtampovannyh parts that work at temperatures up to +450°C; These alloys are used in the design of supersonic aircraft, for the manufacture of brackets, beams and similar power details.
