When brazing cast iron, graphite must be removed from the surface to assure good wetting. May facilitate stress cracking of some alloys by liquid metal embrittlement; prior stress relief annealing is required then, or use of a higher melting point alloy that does not melt until stress relief temperature of the base metal is reached.
Brazing has many advantages over other metal-joining techniques, such as welding. Since brazing does not melt the base metal of the joint, it allows much tighter control over tolerances and produces a clean joint without the need for secondary finishing. Additionally, dissimilar metals and non-metals (i.e. metalized ceramics) can be brazed. [2]
