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.Carpenter Glass Sealing 27 is a ductile chromium-iron alloy that has been used for strong glass-to-metal seals in electronic and vacuum tubes, and incandescent and fluorescent lamps. It exhibits no phase transformation up to 1150 deg C (2100 deg F).
