SUMMARY
The reaction between aluminum and palladium is highly exothermic, particularly in the context of palladium-clad aluminum wires, known as Pyrofuze. This reaction initiates at 600 °C, the melting point of aluminum, and can reach temperatures between 2200-2800 °C. Notably, this reaction occurs without the need for oxygen, resulting in the complete consumption of the wire. Such characteristics make it a significant example of an exothermic alloying reaction.
