A newly approved aluminium scrap grade named Vesper is expected to alter how wrought-aluminium scrap is processed and traded globally, promising improved quality standards and potentially affecting scrap supply flows and pricing.

Summary :

EOL vehicles feed today’s Zorba and Twitch streams. Zorba carries 70–90 per cent aluminium mixed with other metals. Twitch, sorted from Zorba, typically contains 91–93 per cent aluminium but is still a blend of cast and wrought alloys. Any wrought aluminium content in twitch has historically been downcycled away from its original form and repurposed into cast products. Once this happens, it can no longer be recycled into new sheets or extrusions. 

As aluminium-intensive vehicles such as Ford’s F-150 begin reaching end of life, wrought alloy content is being found in twitch compared to cast alloys. Now, the responsibility lies on companies like Novelis to recover this wrought material instead of allowing it to be downcycled.

Vesper targets this gap. It defines a stream made only of wrought alloy,sheet, extrusion, or plate, segregated from zorba or twitch, with strict limits that preserve melt compatibility. According to ReMA, vesper must contain no more than one per cent  free magnesium, one per cent free zinc, 0.5 per cent free iron, and one per cent free non-metallics. It must also be dry and free of heavily oxidised items, airbag canisters, or sealed or pressurised containers. These guardrails ensure the scrap can feed directly back into sheet and extrusion applications without quality loss.
