VT9 titanium round bar, sheet
General characteristics
Titan brand are classified according to the configuration of the crystal lattice: cubic (β-state), in the form of a hexahedron (α-condition), mixed (α+β). VT9 brand belongs to the group α+β alloys. Alloyed with aluminium and 6.4%, molybdenum — 3%, Zn — 1,5%, silicon — 0.25 percent. Developed в1960 G. Viemam. VT9 is the first thermally hardened alloy, mastered by the industry. The highest strength properties are achieved at temperatures up to 500 °C.
