A SURVEY OF ELECTROFORMING FOR FABRICATING STRUCTURES

Several high-strength structures were produced by electroforming, for specific missile and aerospace applications. Several organizations have electroformed nickel with ultimate tensile strengths of 90,000 to 100,000 psi, or more. Tough notch insensitive, 200,000-psi nickel was electroformed by one or two organizations, but additional information must be developed before such a high strength material can be electroformed consistently in a complexly shaped form. This state-ofthe-art report describes advantages and limitations of electroforming, summarizes available property data of materials, and discusses electroforming conditions that must be maintained for good control of structural properties.
