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.COLMONOY No. 23A and No. 24 comprise two grades of one nickel-base alloy. The two grades arise from proprietary differences in the physical characteristics of the two alloy powders which are applied only with Colmonoy's FUSEWELD* process. No. 23A is superior for repairing surface flaws of cast-iron components and No. 24 is superior for building-up edges or corners of cast-iron components, such as used in the glass industry.
