What is the melting point of aluminum?

• A. 660 C (1220 F)
• B. 550 C (1022 F)
• C. 800 C (1472 F)
• D. 540 C (1004 F)

Answer: (A)

Melting point is the temperature at which a solid starts to turn into a liquid. For pure aluminum, that point is about six hundred sixty degrees Celsius (roughly twelve hundred twenty degrees Fahrenheit). This value is a standard reference in materials data, reflecting aluminum’s relatively low melting point among structural metals. The other numbers shown aren’t the onset of melting for aluminum: they’re either below it, in which case aluminum would still be solid, or above it, meaning melting would have already occurred. Keep in mind that aluminum alloys can have slightly different melting ranges, but the classic reference for pure aluminum is around 660°C.
