👉 Fluid is a type of liquid metal alloy that lacks the rigid crystalline structure found in traditional metals, instead exhibiting a more amorphous, glass-like state. This fluidity arises from its composition, which typically includes elements like aluminum, copper, and silicon, combined in proportions that prevent the formation of a stable crystal lattice. As a result, fluid metal can flow and deform under stress without the brittle fracture common in solid metals. This unique property makes fluid metal particularly useful for applications requiring high ductility and resistance to cracking, such as in specialized casting processes or certain types of electronics manufacturing. However, this fluidity also means it can be challenging to work with, necessitating precise control over temperature and pressure during handling and processing.
