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.BioBlu 27 alloy is a wrought powder metallurgy product produced by vacuum induction melting (VIM) followed by gas atomization and hot isostatic pressing or by VIM plus electroslag remelting (ESR) to produce 100% billets. The finished mill product is supplied in the annealed, hotworked, or warm-worked condition.
