    BEND Metal, 158 F, 70 C Low Melting Alloy
    BEND Metal, 158 F, 70 C Low Melting Alloy
    This is a Bismuth based Eutectic low melting alloy used very often to bend tubes and rolled or extruded shapes. This alloy which is normally used for tubes up to 2-1/2" Diameter allows them to be bent or formed to the desired shape without any kinks. Without using this material the tubes or shapes may kink or bend irregularly. It can also be used for work-holding, fusible safety devices and low temperature soldering.

    FIELD’S Metal, 144 F, 62 C Low Melting Alloy
    FIELD’S Metal, 144 F, 62 C Low Melting Alloy
    Named after its inventor, Simon Quellen Field, Field's metal is Eutectic at 144 F, 62 C. Field's metal is expensive due to the price of indium, which makes up over half its mass. However, as it contains neither lead nor cadmium, it is a less toxic alternative to Wood's metal. It is used for die casting and rapid prototyping.
