Abstract : An investigation was made to determine the properties of copper base alloys at room and elevated temperatures for high heat flux applications. Literature surveys were conducted to study the properties of copper-beryllium, copper-zirconium, and other commercial grades of copper and copper alloys. These properties were compared with experimental data for copper-zirconium and two alloys of copper-beryllium at temperatures up to 1000 F. The test data indicated that the copperberyllium alloys can be obtained in large sizes with strength levels comparable to survey property levels, whereas for copper-zirconium it was more difficult to reach tabulated strengths because the effectiveness of cold working was reduced for large size billets. The final selection of an alloy depends upon the requirements of a specific application.
