Indium is a malleable metal with a low melting point (157℃). With Sn, Pb, Ag etc., it can form a series low melting point eutectic solders .
Features & Benefits
· Low melting point
· Low vapour pressure
· Favorable ductility and malleability
· Good thermal fatigue properties
· Repeatable welding and reflow soldering at low temperature is available.
· Nice resistance in drop tests
· Superior thermal conductivity
Product Application
Indium has a high thermal conductivity (86W / mK at 85°C). Therefore, it is widely used in thermal management, and the heat generated by electronic components can be effectively eliminated through it.
· Vacuum electronic devices packaging
· Glass packaging
· Ceramic packaging
· Low-temperature superconductive device packaging
