What is the approximate melting point for silfos?

Silfos is a type of brazing filler metal commonly used in refrigeration applications, particularly for joining copper and copper alloys. The melting point of silfos is typically in the range of approximately 1300 to 1500 degrees Fahrenheit. This makes option B, which states 1500 degrees Fahrenheit, the correct approximation for the melting point of silfos, as it reflects a common upper limit for this material's melting range.

In refrigeration systems, it is crucial to know the melting point of brazing materials like silfos to ensure proper adhesive properties during the joining process. Using a filler metal with an appropriate melting temperature helps achieve a strong joint without damaging the components being joined. Understanding these properties is vital for technicians working in ventilation, air conditioning, and refrigeration, as they directly impact the durability and effectiveness of the system repairs or constructions.
