Abstract

Although Al-Mg-Si alloys are widely used in cast, wrought and extruded shapes, the processes leading to the negative effect of natural pre-aging on artificial aging are still not fully understood. Finding a way to avoid this phenomenon of 6xxx series aluminum alloys has been subject of numerous research studies. Recently it has been shown that minute additions of Sn suppress and/or reduce this effect. Sn retards the hardness increase during natural aging and also enhances artificial aging kinetics and maximum hardness. As these previous studies used material gravity mould-cast in laboratory, a confirmation that wrought sheets or plates behave comparably is pending. The present study investigates the influence of the production route of AA6061 with and without Sn additions, and with two different combinations of Mg-, Si- and Cu-content.
