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.L.T.C. is a gold-nickel-chromium solid-solution alloy developed to meet the need for an improved winding wire for potentiometers of utmost reliability. It is characterized by excellent corrosion resistance combined with an unusually low temperature coefficient of electrical resistance.
