The term alloy revert is one that many industrial manufacturers encounter without a clear definition attached to it. It is frequently confused with scrap, which is an understandable error — but it is an important one to correct, because the distinction affects how you specify the material, how you document it, and how you price it.
This post explains what alloy revert is, how Globe Metal’s alloy revert portfolio is organised, and why it is a material category that aerospace and industrial manufacturers should understand and engage with deliberately.
What Alloy Revert Is and Is Not
Alloy revert is specialty alloy material — most commonly nickel-based or cobalt-based superalloy — that has been recovered from a manufacturing process and returned to a condition suitable for reuse as a raw material.
The key distinction from scrap is that alloy revert retains its original alloy chemistry. A piece of INCONEL 718 that has been machined from a forging, cleaned, inspected, and certified to its original alloy specification is not scrap — it is alloy revert. Its chemistry is the same as virgin INCONEL 718. Its properties, when properly remelted and processed, are equivalent to virgin alloy. And its cost, as a raw material input, is lower than virgin alloy produced from primary ore.
Scrap, by contrast, is material of mixed, uncertain, or degraded chemistry. Scrap may contain multiple alloys, unknown contaminants, or materials that have been heat-treated, plated, or otherwise processed in ways that affect their chemistry. Scrap is priced accordingly.
Alloy revert is not scrap. It is a production-ready raw material with a defined chemistry, proper documentation, and a legitimate place in the supply chains of manufacturers who process specialty alloys.
Globe Metal’s Alloy Revert Portfolio
Globe Metal’s alloy revert offer is divided into two material families: nickel-based superalloys and cobalt-based superalloys.
The nickel-based portfolio covers the grades most commonly used in aerospace turbine engine manufacturing. INCONEL alloys — including the widely used INCONEL 718 and INCONEL 625 — are available as revert in the forms that melt shops and investment casting operations require. Rene alloys, developed originally for General Electric’s turbine programmes, are similarly available. Mar-M alloys, CMSX grades (the directionally solidified and single-crystal alloys used in the hottest sections of turbine engines), and PWA alloys (Pratt & Whitney’s proprietary superalloy grades) round out the nickel-based portfolio.
The cobalt-based portfolio covers alloys used in applications where cobalt’s specific properties — high-temperature strength, wear resistance, and corrosion resistance — are required. HS alloys (Haynes-grade cobalt-based alloys), Tribaloy alloys (cobalt-based with high molybdenum content, used for wear applications), and MP alloys are all available as part of Globe Metal’s cobalt-based revert supply.
The specific forms in which these alloys are available — whether as turnings, solids, chips, or other forms — depend on the material and the current stock. Contact Globe Metal directly to discuss availability for your specific grade requirement.
Why Alloy Revert Matters to Aerospace and Industrial Manufacturers
Superalloy raw material is expensive. For manufacturers producing turbine components, industrial gas turbine parts, or other high-temperature hardware, the raw material cost is a significant proportion of total production cost. Alloy revert offers a route to sourcing the same chemistry at a lower cost than virgin alloy, provided the material is properly certified and the supplier can demonstrate its provenance.
For melt shops and investment casting operations, alloy revert is not a compromise. It is standard practice in the aerospace supply chain. Prime contractors and their Tier 1 suppliers have approved alloy revert as a charge material for decades, provided it is supplied with the traceability and certification required by their quality systems.
The barrier to using alloy revert effectively is not the material itself. It is finding a supplier who can provide material to the correct specification, with the correct documentation, consistently. That is where the difference between a specialist alloy revert supplier and a general scrap dealer becomes apparent.
Documentation Standards for Alloy Revert
Alloy revert supplied into aerospace manufacturing supply chains must meet documentation standards that are specific and non-negotiable. At minimum, the material requires certification of alloy grade, lot traceability, and confirmation that the material has not been contaminated or mixed with other alloys or non-metallic materials.
For specific alloy grades — particularly CMSX single-crystal alloys, which are used in the most demanding turbine sections — the documentation requirements can be more extensive, including chemistry analysis and processing records.
Globe Metal provides documentation with every alloy revert shipment. If your quality system has specific certification requirements, discuss them at the point of enquiry. We can confirm whether our current stock meets your requirements before you commit to an order.
