The Carderock Division Naval Surface Warfare Center intends to negotiate a sole source procurement with Lake Erie Design Co. for the manufacture of a thin, leachable ceramic core. The cores are for a 6.2 research and development project to explore a new way to make bronze castings. The ceramic core shall have the toughness, erosion resistance and chemical inertness to withstand contact with flowing, molten bronze, survive the forces ofcontraction during solidification, and yet be capable of being completely leached out of the bronze casting after it has been cooled without damaging the bronze casting or affecting the properties of the bronze. An acceptable leachant for the cores is 40 percent sodium hydroxide at 150 degress fahrenheit. Only one responsible source and no other supplies or services will satisfy agency needs under the authority of FAR 6.302.1. Anticipated award is on or about 9/9/96. See Numbered Note(s): 22. (0233)
