View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.CERAMETiL 616, 716, 721 are silver brazing filler metals with a titanium-bearing coating to facilitate brazing to ceramics and other hard-to-wet materials without the need for prior metallizing procedures. Alloys are covered under U.S. Patent No. 5,186,380.
