The low temperature effect on the characteristics of lead-free alloys based on tin (Sn) were analyzed. The allotropic transformation of white tin into grey tin at temperatures below 286 K were studied. The effects of prolonged exposure of Sn-0.5 copper alloy and Sn-37 lead alloy to low temperatures were also studied. The results showed that tin pest at low temperatures lead to the disintegration of real joints.
