This study was conducted to evaluate the potential use of currently available 2091 and 8090 alloys as forging material. Three different product forms have been studied : - Precision die forgings such as window frames, fittings... - Conventional die forgings such as wheels, tubes... - Thick hand forgings (thickness up to 150 mm)

This paper presents t h e s t a t e of development a t PECHINEY in t e r m s of property goals (replacement of existing alloys) and product forms. T h e main a r e a s of research in progress, achievements and prospects regarding commercialization a r e given. Typical values measured on sheets, extrusions, forgings and tubes a r e given, t o g e t h e r with engineering properties. Most results r e l a t e t o d a m a g e tolerance and medium strength types of replacement. They a r e all based on industrial production. Progress regarding t h e o t h e r product forms, mainly t h e thicker ones, and regarding higher strength alloys will also b e outlined.
