摘要： This invention relates to brazing filler metal compositions that have excellent wettability to nickel/cobalt/iron-based base metals and produce braze joints with high strength and heat/corrosion resistance. The iron-based braze filler metal of the present invention comprises chromium in amounts between about 20 to 35 percent by weight, silicon in amounts between about 3 to 12 percent by weight, and phosphorus in amounts between about 3 to 12 percent by weight; the balance being iron. These filler metals are suitable for the manufacture of several different types of heat exchangers and catalytic converters at a significantly lower cost compared to currently known braze filler metal compositions.
