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
Titanium Bicycle brand WH, VT6, has a high specific strength, corrosion resistance, namagnichennosti. These alloys its strength is not inferior to the strength of steel, but lighter by almost half, are heat resistance, low thermal conductivity, easy stamped and forged. For corrosion resistance superior to stainless steel. Although the cost of titanium alloys is high, since the production of their labor-intensive and energy-intensive, but a winning combination of qualities makes them uncontested material. Despite the high cost, the materials based on titanium are widely demanded of modern industry.
Use
High specific strength, corrosion resistance of the alloy VT6 allow it to be used in the manufacture of airframe, landing gear, plating, power set, tools pylons, wing, hydraulic cylinders parts, in rocket (fastenings, plating), production of turbofan engines. Thanks to its resistance to chlorinated and sea water, from alloy VT6 made heat exchangers, propellers, marine equipment, tanks for chemical engineering. Biological inertness makes it possible to produce from alloy VT6 implants for surgery. Alloy brand WH claimed in the manufacture 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.
