Nickel Cobalt Alloy Ingot (Ni50/Co50) Description

The ingot’s homogeneous microstructure (grain size <50 μm) and ultra-low impurities (O <50 ppm, C <0.01%) ensure exceptional mechanical stability. It retains yield strength >550 MPa at 800°C due to cobalt’s solid-solution strengthening. Thermal conductivity (70 W/m·K) and low thermal expansion (13 ppm/°C) prevent warping in thermal cycling. Suitable for hot forging, extrusion, or machining into turbine disks, nuclear reactor cladding, and precision tooling.

Nickel Cobalt Alloy Ingot (Ni50/Co50) Applications

·          Aerospace: Turbine disk forging, afterburner components.

·          Nuclear: Fuel rod cladding, reactor pressure vessels.

·          Industrial: High-temperature dies, extrusion mandrels.
