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

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
