Recycling metal by solid bonding

Solid Bonding Picture

The production of metal components by machining is widespread, particularly in high performance applications such as aerospace. The most common manufacturing route is to machine a final part from a large rectangular block of aluminium, generating large quantities of “swarf”—small chips of aluminium.

Solid bonding is an emerging process that can bond aluminium chips into solid material without the need for melting. Ongoing trials by the WellMet2050 team in collaboration with Technische Universität Dortmund are evaluating the technique, with the aim of promoting solid bonding as a mainstream alternative to recycling by melting of aluminium.
