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.SeBiLOY II is a newly developed selenium/bismuth-modified cast red brass alloy. Its low lead content helps meet the National Sanitation Foundation's standard on low lead pickup in water supply systems. The Se/Bi modification permits machining exactly like the leaded red brasses it is replacing.
