What materials is useful for making molds because it has a low meting point?

Materials like low-temperature alloys, particularly those in the fusible metal category, are useful for making molds due to their low melting points. Alloys such as Wood's metal and Cerrotruco melt at around 70-100°C (158-212°F), allowing for easy shaping and casting without requiring high temperatures. These materials are particularly advantageous in applications like prototyping or creating molds for casting other metals.
