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 meeting point allows it not to distort the glass or plastic which it supports, Also can be used for proof casting as well. In comparison to its 117 Deg F. counterpart this alloy does not contain Cadmium. Forms: - 2 Lb. Cake Even Weight

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

This is a Bismuth based Eutectic low melting alloy whose main attribute is the minimal volume change between its liquid and solid state. This is the highest melting point of the bismuth-base alloys commonly used in the industry and provides an easily castable material ready for use soon after it freezes. It is used primarily for holding parts such as jet engine blades for machining and also for foundry patterns and fusible elements in safety devices. Forms: - Cakes

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. Forms: - Cakes

This is a Bismuth based non-eutectic alloy commonly used as a low-melting solder and also to make custom shaped blocks. It is also used to make metal inlays in wood and also useful for repairing antiques as the low melting temperature of Wood's metal makes it unlikely this will harm the original piece.
