Titanium alloy BT20 belongs to pseudo-alpha alloys. The proportion of titanium in the alloy can reach from 85.15 to 91.4%. In addition, the composition includes from 5 to 7% aluminum, 1.5-2.5% zirconium, 0.5-2% molybdenum and 0.8-2.5 vanadium.
A significant proportion of aluminum contributes to the high heat resistance of the alloy and mechanical strength. Titanium metal VT20 is somewhat inferior to alloy OT4 in terms of plasticity and manufacturability during pressure treatment, but it is excellently deformed when hot.
Material is supplied in foil, sheet, strip, tape, plate, rod, profile , pipes, welded and solid-rolled rings, stamping, up to 250 mm thick.
Any type of welding can be used to weld an alloy. At the same time, the strength of the seam remains similar to that of the materials being welded.
Not quite democratic price for titanium, it is fully justified by its high performance.
You can buy a sheet, profiles, or a titanium pipe for the manufacture of parts that are corrosion resistant and able to work for a long time, at temperatures up to 500 degrees. Thus, VT20 is successfully used in the aircraft industry, for the manufacture of wing skins, welded assemblies and other parts operating at temperatures from -70 to 500 degrees.
