CO6627 1.4977 Cobalt Nickel Alloy Powder

1.4977 Cobalt-Nickel Alloy Powder Description

1.4977 Cobalt Nickel Alloy Powder is a high-performance alloy based on cobalt, designed for use in extreme environments that require high mechanical strength, thermal stability, and wear resistance. It is produced as a spherical powder—typically by gas atomisation—and offers excellent flowability, packing density, and uniformity, making it well-suited for additive manufacturing, thermal spraying, and other powder metallurgical applications.

This alloy maintains its structural integrity at high temperatures and exhibits excellent oxidation and hot corrosion resistance due to its high cobalt and chromium content. The presence of nickel enhances toughness and ductility, while carbon and tungsten contribute to high hardness and wear resistance by forming stable carbides. 1.4977 also demonstrates good creep resistance, making it a reliable material for components exposed to prolonged thermal and mechanical stress.

The microstructure is stable over a wide temperature range and resists deformation, grain growth, and fatigue. These properties make it ideal for high-load high-temperature parts in critical applications within aerospace, energy sectors, and heavy machinery manufacturing.
