Novel high chromium containing braze filler metals for heat exchanger applications

摘要

A new family of boron-free, high chromium containing braze filler metal compositions were developed. Filler metal properties including metallurgical phases, melting range, flow, corrosion resistance and high temperature oxidation resistance are reported. Additionally, the technical and economical advantages of using these new filler metals in fabricating flat plate type of heat exchangers and metallic catalytic converters is discussed.
