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.FANSTEEL 80 METAL is a columbium-base alloy containing nominally 1% zirconium. It is produced by electron-beam melting which gives it exceptionally high interstitial purity. It is several times stronger than pure columbium at elevated temperature; and this is without sacrificing the ease of fabrication associated with columbium. Fansteel 80 Metal can be fabricated easily at room temperature and high-quality ductile welds are possible. Its applications include nuclear, liquid metal loops and structures for high-temperature environments.
