Material Notes:
Lowest melting point practical solder. Indium-tin eutectic with sharp melting point. Has good wettability on glass, quartz and many ceramics. Has good low temperature malleability and therefore compensates for some difference in coefficient of expansion when dissimilar materials are soldered.Information provided by the manufacturer, Indium Corporation.
