Web12 de abr. de 2024 · Low melting point metal (LMPM) is a kind of metal or alloy having excellent thermal conductivity and high volume latent heat, and is also known as liquid metal [22], [23], [24]. Through material modification, different melting points, viscosities, and thermal conductivities can be achieved [25] , [26] , [27] . WebSolution. Because they have very low melting points compared to most other metals (except for mercury). The melting point of gallium is 29.77°C (85.59°F), which is low enough that the temperature of your skin may be warm enough to melt it. The melting point of cesium is 28.44°C (83.19°F), also within range of normal skin temperature.
