high-strength and anti-corrosion aluminum foil for car radiator fins and a manufacturing method of the high-strength and anti-corrosion aluminum alloy foil.
The aluminum foil comprises the components of, by weight, 1.0-1.3% of manganese, 1.0-1.3% of silicon, 0.3-0.6% of iron, 0.2-0.4% of copper, 0.3-0.8% of samarium and the balance aluminum. According to the high-strength and anti-corrosion aluminum alloy foil for the automobile radiator fins and the manufacturing method of the high-strength and anti-corrosion aluminum alloy foil, forming of a large amount of small and dispersed AlMnFeSi second phase is facilitated through the component design of high-manganese and high-silicon of alloy, meanwhile the samarium element and the moderate copper element are added into the aluminum alloy, so that large amounts of reinforced phases Al2Sm and Al10Cu7Sm2 containing the samarium are separated out from an alloy matrix, therefore the mechanical property of the alloy is obviously improved, and the fin foil has the excellent performance that the yield strength is higher than 80 MPa after braze welding is conducted.
