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.SUPEC* G401 AND G402 are resins based on polyphenylene sulfide (PPS) technology. They combine long-and short-term heat resistance with broad chemical resistance and they are inherently flame retardant.
