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.ANACONDA Alloy 1870 is a free-cutting high-conductivity copper. It is a deoxidized copper with lead added to impart free-cutting properties. The various and unusual properties of Alloy 1870 make it suitable for many applications in the manufacture of parts machined from rods and for current-carrying studs, nuts and bolts designed for use at normal temperatures. Because it is deoxidized, it is not susceptible to hydrogen embrittlement if heated in a reducing atmosphere.
