    DETAILED INTRODUCTION
    PRODUCT LIST

    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.
