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.Ti-6A1-4V and its modification Ti-6A1-4V ELI are moderately age-hardenable titanium alloys, the latter containing extra low interstitials to impart additional toughness at sub-zero temperature. This alloy is the most widely used of all titanium alloys and a great wealth of data exists. Ti-6A1-4V is characterized as an alpha rich alpha-beta titanium alloy.
