What is cerrosafe?

Cerrosafe is a type of metal alloy primarily composed of bismuth, lead, tin, and cadmium, known for its low melting point, typically around 158°F (70°C). It is commonly used in firearms and gunsmithing for casting chamber and throat dimensions, allowing for precise measurements without damaging the firearm. Once used, it can be easily melted and removed, making it a practical tool for gunsmiths. Additionally, Cerrosafe is valued for its non-toxic properties compared to other alloy options.
