Pot metal the caster adds other metals to the mix to strengthen the cast part, improve flow of the molten metal, or to reduce cost. With a low melting point of 419 °C (786 °F), zinc is often alloyed with other metals including lead, tin, aluminium, and copper. Pot metal is generally used for parts that are not subject to high stresses or torque. Items created from pot metal include toys, furniture fittings, tool parts, electronics components, automotive parts, inexpensive jewelry and improvised weaponry. It is also used in inexpensive electric guitars and other budget priced musical instruments. Pot metal Pot metal
Liquid metal (Fr)(estimated at 27 °C [81 °F]), and gallium (Ga)(30 °C [86 °F]). Alloy systems that are liquid at room temperature have thermal conductivity far superior to ordinary non-metallic liquids, allowing liquid metal to efficiently transfer energy from the heat source to the liquid. They also have a higher electrical conductivity that allows the liquid to be pumped by more efficient, electromagnetic pumps. This results in the use of these materials for specific heat conducting and/or dissipation applications. Another advantage of liquid alloy systems is their inherent high densities. Once oxides have been removed from the substrate surface, most liquid metals
