The Cobalt-base superalloys have their origins in the Stellite® alloys patented in the early 1900’s by Elwood Haynes.
Although in terms of properties, nickel-based alloys have taken the majority share of the superalloy market, cast and wrought Cobalt alloys continue to be used due to their higher melting points than Nickel (or Iron) alloys, giving them the ability to absorb stress to a higher absolute temperature. Cobalt alloys also give superior hot corrosion resistance to gas turbine atmospheres, due to their high Chromium content, and they show superior thermal fatigue resistance and weldability over Nickel alloys.
Avon Metals recycles Cobalt-based alloy scrap and prepares them for vacuum and airmelt foundry customers around the world. Our purpose-built revert processing facility is state-of-the-art, and incorporates the latest analysis, mechanical, thermal and chemical equipment and processes to ensure that we meet the exacting standards of our clients.
