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.BELMONT ALLOY 2405 is a tin-base alloy that can be melted easily. Being non-eutectic it melts through a temperature range, namely 281 to 338 F. It is used widely for proof casting in foundries, for sealing and soldering in low-temperature work, and for lost-wax pattern dies.
