Abstract

A failure analysis of fractured deep-drawn 1050 aluminum (Al) circles revealed that the tensile strength and especially the tensile elongation of the stock material were out of specifications, leading to fracture during the drawing process. The cracks appeared on the walls of the drawn components, which are produced from 0.40 mm thick 1050 Al circles. The circle stock originated from an unknown supplier. The microstructural characterization of the circle stock indicated a coarse grain structure (180 to 220 µm), and observations of the failure areas revealed the presence of pronounced “orange peel.” Comparison was made with a raw material that originated from a registered and certified supplier in order to demonstrate the differences between the raw materials of the defective and sound products.
