Basic qualities

Titanium rolled products made of titanium alloys BT6 and BTCH have high specific strength, corrosion resistance and non-magnetic properties. These alloys are as strong as steel, but almost twice as light. They are notable for their heat resistance and low thermal conductivity, but they are easily forged and stamped. In terms of corrosion resistance, they are superior to stainless steel. Though the cost of titanium alloys is high (their production is energy- and labor-intensive), thanks to the advantageous combination of virtues, titanium is unrivaled. Despite the high cost, its alloys are widely in demand as they are exceptionally durable.

Longitudinal strength of VT6 rod

E - longitudinal direction of cut samples; P - transverse; H - elevation, T - tangential. In parentheses - shear resistance MPa

Longitudinal strength is the maximum stress that fractures the material at a given temperature, after a specified time.

Heat resistance of BT6 bar

Heat resistance is defined by the creep limit - the amount of stress that deforms the material by a given amount at a given temperature. The index through a fraction is the deformation and the time (in hours) in which this deformation occurs.

Application

Titanium alloy VT6 is used in the production of parts for aircraft engines (stopper, KDN housing). It is used to produce rocket parts and critical fasteners. It is in demand in chemical engineering, the production of sports equipment, parts of household appliances, parts and structural elements working in contact with fresh and sea water. Biological inertness allows to make surgical implants from VT6. Alloy VTCH in demand in the manufacture of press-welded parts, continuously operating at t ° up to +450 ° C, they are used in constructions supersonic aircraft, as well as for the manufacture of beams, brackets and similar force components.
