It is well known that aluminium is recyclable and it saves significant amount of energy compare to primary production of aluminium. However, there is a common belief that secondary aluminium quality is bad. In this work, the change in bifilm index and bifilm number of recycled A356 have been investigated. Reduced pressure test was used and samples were solidified under 100 mbar in a sand mould in order to slowly the cool the melt and unravel bifilms. In addition, various ratios of Ti was added to the alloy as 0.1 and 1 wt% by Al5Ti1B. The alloy was melted five consecutive times. It was found that the melt with higher Ti had significantly improved melt quality after each recycling due to sedimentation of bifilms by titanium.
