Using our Materials by Design methodology, QuesTek has designed and developed an improved beryllium-free, high-strength Cuprium® alloy under SERDP/ESTCP project #WP-2138 to be a nontoxic substitute for BeCu and also stronger than existing Be-free Cu-based alloys. This project builds upon an earlier NAVAIR-funded, two-year-long SBIR Phase II project awarded to QuesTek. Beryllium is classified as a human carcinogen via inhalation by the National Toxicity Program and the International Agency for Research on Cancer. Mechanical Properties (Room Temperature) The properties presented below are from heat-treated centrifugal castings without any cold working and are representative of very large size castings (achieving >130 ksi YS on 15 inch diameter centrifugal castings). Hence, they are not subject to size limitation issues experienced by Cu-Ni-Sn alloys. Thus, in the cast state this Cuprium alloy can be used for large-scale components where forgings are not possible. Material and Licensing Availability QuesTek is currently seeking initial product applications for this alloy, and is also in discussions with potential production/sales licensees. Please contact QuesTek to obtain custom ingots or castings for initial product applications, or for more information. This alloy is patent pending. We’re always interested in speaking with major end-users/OEMs about their needs for Be-free, high-strength alloys, as well as also speaking with potential licensees, in order to further optimize production processing and commercialize this material.
