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.

OSTALLOY 160-190 is a low-melting bismuth-base alloy. It is a non-eutectic alloy and melts through the temperature range 160-190 F. It shrinks immediately upon solidification, grows back to zero in about one hour, and then shows additional growth. This shrinkage-growth behavior makes it an ideal alloy for proof casting and precision measurement of internal dimensions.
