Brazing uses a non-ferrous filler material at temperatures above which value?

• A. 600F
• B. 700F
• C. 800F
• D. 1000F

Answer: (C)

Brazing is defined by using a filler metal that melts at a higher temperature than typical solders, so the joint is formed by heating until the filler metal melts and flows into the joint without melting the base metals. The commonly cited threshold for distinguishing brazing is about 800°F. Heating above this ensures the non‑ferrous filler is molten and can flow into the joint by capillary action, while heating below this would align with soldering, where the filler metal melts at much lower temperatures. Therefore, 800°F is the appropriate reference point.
