Characteristics of the alloy

Titanium alloys BT6, BT6S belong to α+β-alloys. Titanium is produced according to GOST 19 807-74 and OST 90 013-81. VT6 is alloyed with 6% Al and 4.5% V, whereas BT6C is alloyed with 5% Al and 4% V. Aluminum hardens α+β phase, and vanadium stabilizes β-phase and hinders the formation of alpha-2 superstructure in α-phase. The annealed state contains 10% of the β-phase. Quenching and aging increase the strength by about 15 - 20% while maintaining a fairly high ductility. Casting variant of VT6L.

BT6 alloy is used in annealed and heat hardened condition. The annealed alloy contains about 10% β-phase. It is highly technical in pressure processing, a variant with a reduced percentage of impurities (BT6kt) is used at cryogenic temperatures down to -196 ° C.

Spec. t° melting point. Properties Technology Application
4.43 g/cm³ 970-1010° Combines strength, high processability and service properties. In annealed condition it is an alloy of medium strength. The maximum working temperature is +350°. It has high workability in pressure treatment, good casting properties and is easily welded by all kinds of welding. Parts of aircraft engines (stopper, RDC housing), rocket parts, parts of fasteners, chemical engineering, parts of household appliances, sports equipment, parts of structural elements operating in water, surgical implants.

Punch-welded parts are made of HTS titanium alloy, continuously operating at up to +450°C; they are used in supersonic aircraft structures for making beams, brackets and similar power parts.
