Steel and aluminum are two very different metals, and getting them to bind together in a stable, continuous weld has been next to impossible on any kind of large scale. Honda Motor Vehicles has announced that it’s doing just that.
The solution has come via a variation on friction stir welding, and will allow Honda to join the materials via mechanical pressure in a way that will change how it make its cars — leading to better performance.
