摘要： Lead alloy strip material (4, 6, 8) is roll bonded on one or both opposite face surfaces of a core strip material (2). The core material can be commercially pure titanium, austenitic stainless steel, low carbon steel, copper, aluminum, alloys thereof or other suitable metal that has sufficient ductility and that can provide desired attributes of stiffness and corrosion resistance to the composite. The lead alloy material is strengthened by the addition of less than approximately 1% of calcium or antimony and the core material is softened by fully annealing it prior to bonding. The several strips are reduced in thickness, preferably in approximately the same proportion, by at least 40% in the bonding pass to create a solid phase bond among the strips. The bonded composite is then rolled to final gauge and, for selected applications, is corrugated and cut to form panels (20, 22, 24) and etched to form pockets (8b) for pasting of active materials such as lead oxide for battery plates.

摘要翻译：铅芯合金条材料（4,6,8）在芯条材料（2）的一个或两个相对的表面上滚动粘结。核心材料可以是商业上纯钛，奥氏体不锈钢，低碳钢，铜，铝，它们的合金或具有足够的延展性的其它合适的金属，并且可以提供对复合材料的刚性和耐腐蚀性所需的属性。通过添加少于约1％的钙或锑来增强铅合金材料，并且通过在结合之前将其完全退火使芯材料软化。在条带中，若干条的厚度，优选以大致相同的比例减少至少40％，以在条带之间产生固相结合。然后将粘合的复合材料轧制成最终规格，并且对于所选择的应用，是波纹状的并且被切割以形成板（20,22,24）并被蚀刻以形成用于粘贴活性材料（例如电池板的氧化铅）的凹穴（8b）。
