Alumobility, a non-profit organisation working on technical solutions to advance the adoption of aluminium automotive body sheet, says ARO, Atlas Copco and Sika have joined as new members.

Operating in a variety of joining techniques for aluminium and other metals, these partners will contribute know-how of assembly methods of aluminium auto body sheet components such as closures, body structures and battery enclosures.

“We are thrilled to welcome ARO, Atlas Copco, and Sika to Alumobility,” said Alumobility executive director, Mark White.

“Their expertise in welding, self-pierce riveting, flow drill fastening, adhesive bonding and other joining methods, will demonstrate reliable, efficient and cost-competitive manufacturing solutions for aluminium automotive body structures and components.

“By working together, aluminium producers and downstream providers can help automakers better realise the increased benefits of light, strong, sustainable aluminium.”

Launched in January, 2021, by founding members Constellium and Novelis, Alumobility conducts technical studies to help automakers use aluminium automotive body sheet.

A new study on the latest joining methods is planned to be introduced this autumn to demonstrate the value and performance of various joining scenarios that can be applied to aluminium-intensive vehicles, as well as mixed material structures.

Findings from this study will be shared in upcoming global auto industry conferences and presented in detail at an Alumobility webinar.

The project follows the consortium’s study on aluminium door design that showcased a 45% weight savings compared to steel doors, while meeting or exceeding safety specifications and other customer performance criteria.
