At what temperature does 50/50 solder melt?

The melting point of 50/50 solder, which is a mixture of 50% tin and 50% lead, typically falls around 361 degrees Fahrenheit. However, it should be noted that for certain applications, such as HVAC systems, the commonly referenced melting point is often stated as approximately 400 degrees Fahrenheit. This figure takes into account the range within which the solder becomes workable and can efficiently join metal components without compromising their structural integrity.

In the context of soldering, an accurate understanding of the melting temperature is critical for ensuring effective bonding of metal parts. If the temperature is exceeded, it can lead to poor joint quality or damage to the components being soldered. This makes a comprehension of the properties of solder, including its melting point, essential for HVAC professionals.

The other options suggest temperatures that do not align with the commonly accepted melting points for 50/50 solder, highlighting the importance of knowing the precise figures relevant to practical applications in HVAC tasks.
