Beryllium sheet, .020 gage, was successfully prepared and brazed with steel and titanium honeycomb core to form a sandwich panel. Commercially available silver based alloys may be used for this purpose, however, an undesirable amount of diffusion or dissolution of the base metals may be experienced. The breakage as ociated with thin gage beryllium during handling or sawing is greatly reduced when the sheet is brazed into a sandwich. The full potential of brazed construction will not be realized until a braze alloy with properties compatible with beryllium has been developed. (Author)
