694 (CM-64)       ESPECIFICAÇÕES TÉCNICAS

Alloy 694, also referred to as Coast Metal 64, is a cobalt-chromium-tungsten alloy providing high strength and stability at temperatures up to 2100°F. Deposits of alloy 694 have outstanding resistance to wear, erosion, creep, thermal fatigue and oxidation. The principal application is for hard-facing turbine blade interlock surfaces.
Wire diameters 0.035", 0.045" and 0.062" are available in straight cut lengths or layer wound spools. This alloy is also available in shaped squares, flats and diamonds sized per customer requirements.
