Aluminum fails at what temperature in fire conditions?

Explanation:
Aluminum fails in a fire when it reaches its melting point, since its structural strength collapses as it melts. The melting point of aluminum is around 660°C, which is about 1200°F. At roughly this temperature, the metal can no longer carry load and begins to flow, leading to rapid failure of the member. The other temperatures either keep the metal solid (though weakened) or push it into melting, but the critical failure point for aluminum in fire conditions is near 1200°F.
