Who is correct regarding the melting point of aluminum compared to steel?

When comparing the melting point of aluminum to that of steel, it's important to recognize that aluminum has a significantly lower melting point than steel. The melting point of aluminum is around 660 degrees Celsius (1220 degrees Fahrenheit), whereas for typical steel, it ranges from about 1370 to 1510 degrees Celsius (2500 to 2750 degrees Fahrenheit) depending on the specific alloy.

If both technicians in the scenario correctly state this comparison—that aluminum melts at a lower temperature than steel—then it would be accurate to say that both technicians are correct in their assertions. This understanding is crucial in collision repair and refinish work, as it influences the processes and techniques used in welding, cutting, and repairing vehicles made from these materials.

Their correct acknowledgment of the differing melting points underscores the significance of material properties in automotive repair, leading to proper techniques to avoid damaging aluminum components while working with steel parts. The knowledge of these differences allows technicians to select appropriate tools and methods for effective restoration of vehicles.
