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.ZGS Platinum is a grain stabilized platinum containing a small amount of highly dispersed zirconium oxide. Its properties combine to provide greater high-temperature strength and, in some applications, greater contamination resistance than that of pure platinum. Applications include laboratory crucibles and dishes. An exacting application is in the production of fibre glass which invloved the rapid flow of molten glass at temperatures of 1250-1350 C through a pierced plate which must retain its shape and alignment.
