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. Forms: - Cakes
- Slug

This is a Bismuth based non-eutectic alloy which has unique properties of shrinking immediately upon solidification and growing back to zero in 1 hour, followed by additional growth. This shrinkage-growth makes it an ideal alloy for proof casting and precision measurement of internal dimensions. Forms: - 2 lb Cakes

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. Forms: - Approximately 2 lb Cakes
Belmont Product Code 2330 Nominal Composition: - Bi: 32.5%
- Sn: 16.5%
- In: 51%

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. Forms: - 2 lb Cakes Even Weight
