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.NICROBRAZ 30 is used for well diffused, high strength, heat resistant joints, and highly stressed structures such as jet engine parts. It is also used in nuclear reactors where boron cannot be tolerated. It has low base-metal penetration.
