Stellite 6 Welding Electrode ECoCr-A Electrode Hard Facing Electrode Engine Valve Turbine Blade
WLCo6 cobalt-chromium-tungsten alloy cobalt base surfacing welding electrode, Dc reverse connection, with good comprehensive performance. It is considered the industry standard for general wear applications and has excellent resistance to many forms of mechanical and chemical degradation over a wide temperature range, while maintaining reasonable hardness levels up to 500°C(930°F). At the same time, it has good impact resistance and cavitation resistance. WD-Co6 is ideal for a variety of surfacing processes and can be machined with carbide cutting tools. Examples include seats and gates, pump shafts and bearings, corrosion protection devices and rolling couples. It's usually self-mated.
