Bismuth-indium refers to an alloy primarily composed of bismuth (Bi) and indium (In). Both of these metals have low melting points compared to other metals, which make their alloys useful in various applications. Bismuth itself has a melting point of about 271.4 °C (520.5 °F), while indium melts at around 156.6 °C (313.9 °F).
