Description Colmonoy 5-S is a premium nickel-base alloy powder which is crushed from a fully alloyed shot. The proprietary two-stage process produces and promotes formation of hard phases in the coating or overlay deposit that contain: Microstructural Constituent Chromium Boride Chromium Carbide Primary Solid Solution Secondary Solid Solution Eutectic Composition Microhardness (DPH) 4100 2500 450 800 1000 Ultimate Compressive Strength: 275 ksi (average) Tensile Strength: 60 ksi (average) Magnetic Permeability: 1.005 Coefficient of Friction: 0.1 (6 micro-inch) Coefficient of Thermal Expansion: 8.4 x 106 per F° Hot Hardness Rockwell C Scale 600°F 800°F 1000°F 1200°F 46 45 41 38 75°F 45-50 The alloy is used for hard surfacing parts to resist wear, heat, corrosion and galling. It has greater ductility and better impact resistance and workability than Colmonoy 6, and displays excellent finishing characteristics. whenever possible.
