Making Strong Carbide to Steel Joints Braze with Confidence

When brazing tungsten carbide bits to steel to create a mining tool, silver braze alloys are often not the braze alloy of choice. Rather, filler alloys are chosen that melt at higher temperatures than silver alloys. Below are threemended alloys for brazing mining tools. Note that all three contain manganese, which plays a vital role in brazing carbide. The braze alloyes in the
