Check out our revert guide Who We Supply

Revert Alloys

William Rowland Revert Alloys, specialises in the purchasing and sales of specialty revert alloys, metals and scrap materials. These are recycled and repurposed metals and alloys that take various forms, such as sheet cuts, plate, bar ends, broken cathodes, powders, briquettes, ingots, and turnings. Our in-house team expertly sort, clean and process the revert alloys for safe reintroduction into the supply chain - this process is called upgrading. Once sorted, the metals and alloys can be re-melted and then are repurposed. We can repurpose any metal or alloy as we have Vacuum Induction Melting (VIM), Electric Arc Furnace (EAF) and Air Induction Melting shops.

Below is our Revert Alloy Guide which has been designed to guide you through which elements our metals are made up from. Please get in touch with our specialists for more information.
