The Future of Waste NdFeB Rare Earth Permanent Magnets and their Role in a Circular Economy
Abstract Summary

The E-mobility evolution can be a real new opportunity for aluminium high pressure die casting , providing that component's development can rely on innovative processes for innovative products. If so, the reduction of ICE – Internal Combustion Engine – components in the cast aluminium utilization forecast could be narrowed down



Full Abstract

Lightweight materials like aluminium are currently in high demand for an electric vehicle as low weight equals longer range or a reduction of the battery cost .

Nevertheless the fast developing BEV (Battery Electric Vehicle) segment could lead to an overcapacity in the aluminium casting industry around 2020 – 2025 if production technologies will not evolve to meet needs for larger components with high level of function integration.

Aluminium foundries supplying the ICE powertrain together with peripheral components such as pump housings are in the danger zone. To cope with the additional demand HEV (Hybrid Electric Vehicle) & PHEV ( Plug In Hybrid Electeric Vehicle ) cast aluminum components, some capacity has being recently added in European foundries, some of which will become shortly obsolete as the BEV share increases.

As a matter of fact BEV vehicles contain much less cast aluminum in the powertrain area compared to ICE, HEV and PHEV . All casting technologies, successfully producing engine components like cylinder block , cylinder head, oilpan , turbochargers , manifolds , and the few needed BEV components (i.e. battery housing & electric engine rotors) require larger size HPDC (High Pressure Die Casting ) machines ( in the range of 4200 tons ) and evolved casting process technologies.

An overview on alloys and combined foundry technologies, suitable to cope with the E-mobility will be given.
