What effect can excessive heat have on aluminum during repairs?

Excessive heat applied to aluminum during repairs can cause the metal to melt and distort. Aluminum has a relatively low melting point compared to other metals, around 660 degrees Celsius (1220 degrees Fahrenheit). When aluminum is subjected to temperatures above this threshold, it can start to lose its structural integrity, leading to melting. Even before reaching the melting point, high temperatures can cause the aluminum to lose its tensile strength and become malleable, leading to permanent distortion.

Understanding the thermal properties of aluminum is crucial during repair processes, as maintaining appropriate temperature levels ensures the metal retains its strength and form. Awareness of the effects of excessive heat helps technicians avoid damaging the material beyond repair, which is critical for vehicle safety and performance.
