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.EVANOHM* alloy S offers optimum stability and flexibility with regard to both size and required temperature coefficient of resistance. Its extremely low electromotive force vs copper together with its high electrical resistivity are highly desirable properties in a precision resistance wire.
