In furnace brazing, temperatures of 2050 to 2100°F and above are not uncommon, especially when brazing stainless steels with nickel-based filler metals or carbon steel with copper filler metal. Other very high temperature brazing applications include molybdenum with pure nickel as the filler metal and cobalt with a cobalt alloy filler metal.
