The invention belongs to the field of aluminum
alloy foil rolling and discloses high-strength, high-elongation and
corrosion-resistant
aluminum foil for a
honeycomb core and a manufacturing method thereof. The high-strength, high-elongation and
corrosion-resistant
aluminum foil for the
honeycomb core is composed of, by
mass, 0.40-0.60% of Fe, 0.15-0.30% of Si, 0.07-0.16% of Cu, 1.10-1.62% of Mn, smaller than 0.05% of Mg, 1.0-1.60 % of Zn, smaller than 0.05% of Ti, and the balance aluminum. The manufacturing method comprises the steps of
smelting,
casting-rolling, cogging and rough rolling, high-temperature annealing, intermediate rolling, intermediate trimming, finishing rolling, slitting, inspection and packaging and the like. The prepared
aluminum foil finished product has the characteristics of being high in mechanical properties, high in
impact resistance, high in elongation and easy to stretch and
cut; wrinkling is not prone to happen in the core making process, the bonding quality is good, and the
dislocation error is small; and meanwhile, an obvious
potential difference exists between the aluminum foil and glued aluminum plates on both sides of the aluminum foil, so that a sacrificial protection effect can be formed to improve prolong the
corrosion resistant life of a
honeycomb panel.
