Abstract
Sheet metal formabilities for aluminum 1050 and 5052 were experimentally investigated in this study. Deep drawability, bendability and stretch formability were measured at each process condition and correlated with tensile properties of sheet metal. To compare the formabilities of aluminum 1050 and 5052 sheets with those of steel sheets, deep drawing quality(DDQ) steel sheets are also tested at the same test conditions. Through the experimental studies, influential process variables for each forming process were obtained and correlated with the tensile properties. The comparisons of sheet metal formabilities with those of steed sheets showed that aluminum 1050 and 5052 is inherently deficient in formability than steel sheets but Al 5052 that has highter n and r value than al 1050 showed better formabilities.
