Several aluminium and titanium alloys showing superplastic properties are important for aerospace application. This offers chances to fabricate complex shaped components in one piece and one step. After a short review to the metallurgical basis of superplasticity and diffusion bonding of these alloys the relevant processing parameters are presented. Parts from titanium and aluminium alloys are shown for space, helicopter and aircraft application. These parts have been designed to SPF and fabricated. The process (e.g. over or press) and the manufacturing process (e.g. design and material of the forming tool) have been optimized to lost and quality for each type of part. The state of production is reported.
