Elements of Indium by Indium Corporation: Low Melting Point

In celebration of Indium Corporation's 85th anniversary, the company will release monthly installments of the Elements of Indium Series—an educational program to raise awareness  of the unique applications, abundance, and interesting properties of the 49th element.

Indium Corporation is the global leader for indium metal and associated technologies. Because of its unique properties with virtually limitless applications, indium metal is literally all around us.

One of indium metal's unique characteristics is its low-melting point. Low-temperature alloys, which typically contain indium or bismuth, melt at temperatures less than 180°C. These alloys are used in a wide variety of applications, including:

  • Step soldering involving temperature-sensitive components
  • Soldering to molded interconnect device (MID) plastics
  • Fusible alloys and fuse applications
  • Thermal and electrical conductivity

Because of its low melting point, indium and bismuth alloys have been used in fire suppression systems for years. These alloys melt at low enough temperatures – from 50 to 100°C – to trigger safety devices in the event of a fire.
