What is the ideal temperature for silver brazing filler metals?

The ideal temperature for silver brazing filler metals is above 800 degrees Fahrenheit but below the melting point of the base metals being joined. This temperature range allows the brazing alloy to properly flow and adhere to the surfaces of the base metals without melting them.

When the filler metal is heated to the appropriate temperature, it becomes fluid enough to be drawn into the joint by capillary action, creating a strong bond. If the temperature exceeds the melting point of the base metals, there is a risk of distorting or damaging the components being joined, which can compromise the integrity and strength of the joint.

This careful temperature management ensures effective brazing and a successful joint, illustrating why the selected answer is accurate for the practice exam.
