A review on effect of alloying elements and heat treatment on properties of Al − Sn alloy

Abstract Aluminum (Al) –Tin (Sn) alloys are potential lead free bearing materials, widely used in automobile and marine applications. These alloys possess good fatigue strength, seizure resistance, corrosion resistance and embedability properties. However, properties of Al − Sn alloy have to be modified to suit for engineering applications. In this paper we present a review on characterization of mechanical and tribological properties of Al − Sn alloys subjected to heat treatment (Annealing) and also effect of addition of alloying elements such as Bi, Mg, Pb, Nano Si and Nano Gr. The review suggests that heat treated alloys exhibited better mechanical properties whereas ternary alloyed samples showed improved tribological properties.
