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.Wieland-L49 has excellent cold working and corrosion properties. Its composition makeup gives it better protection to more severe atmospheres than other copper alloys. Although it does not have as good electrical and thermal properties as other copper alloys, it is used in more critical applications, such as circuit boards, because of its corrosion properties.
