An amalgam of mercury and tin expands, as do nearly all amalgams. The following binary alloys also expand, namely: bismuth and zinc; bismuth and antimony; lead and tin, and lead and antimony.

This alloy is made from Tin and Bismuth, contains no lead and melts at around 280 degrees Fahrenheit. I poured this molten ...

This led to a surge in the price of bismuth on the metal market, and the opening of ... and has been used to prepare low-melting typesetting alloys that need to expand to fill printing moulds.
