What are the common melting points of brazing material and silver solder?

The common melting points for brazing materials and silver soldering typically fall within the range of 1,100 to 1,480 degrees Fahrenheit. This is because brazing processes require a filler metal that melts above 840 degrees Fahrenheit but below the melting point of the base metals being joined. Silver solder, which is often used alongside brazing, also has a similar melting point range due to its composition, which includes silver, copper, and other alloying elements that contribute to its performance and thermal properties.

The options that indicate melting points outside this range, whether significantly lower or higher, do not align with the actual melting points of commonly used brazing materials and silver solders. Therefore, the range provided in the correct answer accurately reflects the properties and applications of these materials in refrigeration and other metal joining applications.
