At approximately what temperature does aluminum begin to melt?

Aluminum typically begins to melt at around 1220°F (660°C). Therefore, the choice indicating approximately 1200°F is the most accurate answer. Recognizing the melting point of materials like aluminum is crucial in fire service operations, especially when considering structural integrity during a fire. As temperatures rise during a fire, structural components made from aluminum can lose their strength significantly before they reach the melting point. Therefore, understanding this critical temperature helps fire personnel make informed decisions regarding the safety and stability of buildings during firefighting operations.
