What is the approximate melting point for solder?

The approximate melting point for solder, typically made of lead and tin, falls around 450 degrees Fahrenheit. This temperature is critical for various applications in refrigeration and air conditioning, particularly in the assembly and repair of components that require soldered joints for secure connections.

Different solder alloys may vary slightly in their melting points depending on their specific composition. However, traditional lead-tin solder commonly used in HVAC systems adheres closely to this melting point, making 450 degrees Fahrenheit the standard reference. Understanding this temperature is important for technicians working with solder in order to ensure proper joint formation without damaging the surrounding materials.
