At approximately what temperature does aluminum melt?

• A. Around 1,200°F.
• B. Around 700°F.
• C. Around 1,900°F.
• D. Around 2,800°F.

Answer: (D)

Aluminum’s melting point is relatively low for structural metals. For pure aluminum, melting occurs at about 660°C, which is roughly 1,220°F. So the option around 1,200°F best matches the actual melting point. The temperature around 700°F is below melting, so aluminum would still be solid at that temperature. Temperatures near 1,900°F or 2,800°F are far above the melting range and would be well into the molten state, not the point where melting begins. In practice, aircraft structures use aluminum alloys with similar melting behavior, so understanding that melting starts around this 1,200°F area helps you gauge how heat exposure from a fire could compromise aluminum components.
