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…

Bismuth is a white, brittle metal with a slight pink color and is typically recovered as a by-product of lead and copper. It is commonly used as an alloying element for various low melting alloys where it is mixed with other metals such as Lead, Tin, or Cadmium. It is also used as well for a lead substitute in other materials. The Needles allow you to have more surface area and pack very tight when melting. They have a purity of 99.9%. |

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 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.
