Vitallium

 

a cobalt alloy consisting of 0.2-0.35 percent C, 1.5-3.5 percent Ni, 25-30 percent Cr, 4.5-6.5 percent Mo, up to 2 percent Fe, 0.3 percent Mn, and 0.6 percent Si. VitalHum is used as a cast heat-resistant material for small and medium (up to 20-25 kg) castings of components of gas turbines (including moving blades), which are used at temperatures up to 800° C.
