The melting point of an alloy of two (binary) or more metals depends on the relative proportions of the ingredients. an eutectic mixture is the mixture where the melting point is as low as possible. Binary eutectic Gold - Au - alloys, with composition and melting points are indicated below: Alloy Component. Weight of Alloy Component.

lead -bismuth coolants. At present time lead and lead-bismuth eutectic are considered most frequently as coolants for nuclear reactors and as materials for liquid metal targets in accelerator -driven s ystems. The choice of lead and lead-bismuth eutectic is determined by the number of favorable thermalphysic and physical -chemical properties.

The eutectic alloy of 58Bi 42Sn (Indalloy ® 281) melts at 138 ° C and is one of the more popular bismuth contained alloys. Low-temperature alloys (including bismuth-containing and indium-containing alloys) need special flux vehicles that have activators lower than standard SMT pastes.
