Eutectic alloys and non-eutectic alloys are categories when discussing low melting alloys. Low melting alloys require lower temperature ranges to melt, anywhere from 40 degrees to 300 degrees Fahrenheit. This property allows for the alloys to be melted at lower temperatures without damaging or impacting other nearby materials or surfaces that the low melting alloy…

This is Bismuth based non-eutectic alloy which does not contract upon cooling. It is mainly used as a solder but also as a heat transfer medium. Another application for this material is to serve as a valve element in automatic fire sprinklers. The valve, having a low melting point, melts in fire and provides water to stop the fire from spreading. |

This is a Bismuth based Eutectic low melting alloy used for tooling and production aids. It provides you with easily castable material that is ready for use as soon as it freezes. This alloy can be recovered easily and recycled into new uses a number of times. It is mainly used in the optical industry for lens blocking when grinding glass, plastic lenses and optical components. It’s low melting point allows it not to distort the glass or plastic which it supports. Also can be used for proof casting as well.

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.

This is a Tin based non-eutectic low melting alloy . The principle uses of this alloy are in applications similar to investment casting in which it substitutes for the so called ” lost wax ” pattern dies. It’s other applications also include proof casting and sealing or soldering in low-temperature applications.
