When joining steel and copper, how does the steel's heat absorption compare to that of copper?

When joining steel and copper, the steel's heat absorption characteristics are distinct from those of copper due to their differing thermal properties. Steel, with its higher heat capacity and thermal conductivity compared to copper, tends to absorb heat more quickly. This allows steel to reach the target temperature necessary for brazing in a shorter amount of time.

However, when it comes to overheating, steel has a tendency to withstand higher temperatures more efficiently than copper, which can easily be prone to overheating due to its superior thermal conductivity. This means that while steel may heat up rapidly, it does not readily overheat as quickly as copper would in similar conditions.

This aspect is crucial in brazing applications because achieving the right temperature without exceeding it ensures a strong and effective bond. Thus, the answer that suggests steel reaches temperature quickly while tending to overheat slowly aligns with the physical properties of these two metals and their performance during the brazing process.
