Creating an alloy with all stable (non-radioactive) metals is theoretically possible but highly impractical due to several factors. Not all metals are miscible, meaning they cannot easily form a homogeneous mixture, particularly when cooled from a liquid state. This immiscibility is influenced by the metals' electronic structures and physical properties, such as density, melting points, and atomic radii. While some metals may mix in liquid form, they often separate upon solidification. Additionally, the vast differences in properties among metals make it challenging to achieve a functional alloy. Although advanced software tools like CALPHAD aid in alloy development, the complexities and proprietary nature of certain mixing processes limit the feasibility of creating such an all-encompassing alloy.
