A metallic foil for lightning strike protection in a composite aerospace structure having a length, a width, and a thickness of not more than 30 microns. There are a plurality of pores of a predefined geometric shape extending through the thickness of the metallic foil and being distributed across a surface area defined by the length and the width of the metallic foil. The plurality of pores in the aggregate define an open area of not more than 40% of the surface area and the metallic foil has a weight of not more than 115 g/m2. The metallic foil has a weight to conductivity ratio of not more than 0.40 gram-ohms per square.
