Twin roll casting is well established as an economical method for producing all types of aluminum foil and heat exchanger fins as well as various grades of building and construction sheet. Recently, there has been an increasing interest in using twin roll casting as a method to produce low-cost/high-quality 5000 series aluminum sheet for automotive structural applications. ASSAN Aluminum conducted a series of tests using a SpeedCaster (R) to produce AA5052, AA5754 and AA5182 strip. This paper compares the microstructure, mechanical properties, formability and corrosion resistance of these twin roll cast materials with samples of similar alloys produced by the DC casting route. In all cases the twin roll cast material is shown to have equivalent, or superior, properties.
