We all know that aluminum is a solid metal, so can solid aluminum become liquid aluminum? The answer is yes. Aluminum can be melted into liquid aluminum when heated to the right temperature. Aluminum has a melting point of about 660 degrees Celsius (1220 degrees Fahrenheit). When aluminum reaches or exceeds this temperature, it changes from solid to liquid.
At high temperatures, aluminum’s lattice structure becomes unstable and its atoms begin to move and lose their solid crystalline form, forming liquid aluminium. Liquid aluminum has low viscosity and surface tension, allowing it to flow and fill containers.
It should be noted that the melting point of aluminum refers to the melting point of aluminum material with higher purity. Aluminum may have a different melting point if it contains other elements or alloying components. In addition, the oxide layer of aluminum also has an influence on the melting process, because the melting point of the oxide layer is higher than that of pure aluminum.
Thus, by heating aluminum to a sufficiently high temperature, it can be melted into liquid aluminium, which can then be utilized or processed by appropriate means.
