This recently developed hot forming process is used to produce sheet metal parts following similar principles to thermoforming: a metal blank is heated to softening point (around 450°C) and formed onto a single-sided tool using air pressure. The process was developed to reduce the weight of metal components by minimising fabrication operation and reduce wall thickness. Marc Newson utilised this process for the frame of MN01, a bike he designed for Biomega. It is manufactured using 5083, which is an alloy of aluminium, manganese and magnesium. It is an excellent all round alloy used in a range of performance applications.
