Elements of Indium by Indium Corporation: Malleability

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.

Indium is a soft and malleable metal that stretches with the metal it’s soldered to. This makes it the perfect solder for joining two metals in order to avoid coefficient of thermal expansion (CTE) mismatch.

CTE mismatch occurs when solder joints containing two different metals expand at different rates. This stress on the solder joint can cause it to crack upon cooling, resulting in the failure of the device.
