Embodiment 1

[0029] In this example, an Al-1.5Fe-0.1La alloy ingot with a thickness of 30mm was prepared by smelting and casting methods, kept at 590°C for 8 hours, milled to a thickness of 25mm, heated at 500°C for 1 hour, and then hot-rolled into a 4mm plate. , then cold-rolled to 0.15mm, annealed at 380°C for 2 hours and then cold-rolled into a foil with a thickness of 0.08mm. The tensile strength of the cold-rolled alloy is 166MPa and the elongation is 3%. After annealing at 250°C for 2 hours, the tensile strength of the alloy foil is 81 MPa, the elongation is 20.4%, and the electrical conductivity is 60.2% IACS.

Embodiment 2

[0031] In this example, an Al-1.5Fe-0.25La alloy ingot with a thickness of 30 mm was prepared by melting and casting methods, kept at 590 ° C for 8 hours, milled to a thickness of 25 mm, heated at 500 ° C for 1 hour, and then hot rolled into a 4 mm plate. , then cold-rolled to 0.15mm, annealed at 380°C for 2 hours and then cold-rolled into a foil with a thickness of 0.08mm. The tensile strength of the cold-rolled alloy is 143MPa and the elongation is 4.4%. After annealing at 250°C for 2 hours, the tensile strength of the alloy foil is 74 MPa, the elongation is 24.7%, and the electrical conductivity is 60.2% IACS.

Embodiment 3

[0033] In this example, smelting and casting methods are used to first prepare an Al-1.2Fe-0.1La alloy ingot with a thickness of 30mm, heat it at 590°C for 8 hours, mill it to a thickness of 26mm, heat it at 500°C, and hot-roll it to 2.6mm. Then cold rolled to 0.15mm, annealed at 380°C and then cold rolled to a foil with a thickness of 0.08mm. The tensile strength of the cold-rolled alloy is 154MPa and the elongation is 2.8%. After annealing at 250°C for 2 hours, the tensile strength of the alloy foil is 80 MPa, the elongation is 23.2%, and the electrical conductivity is 59.4% IACS.

Abstract

The invention discloses a rare-earth La added high-conductivity ternary aluminum alloy foil material and a manufacture method thereof. The foil material is prepared from the following components in percentage by weight: 1.2-1.5 percent of Fe, 0.1-0.25 percent of La and the balance of aluminum. According to the aluminum alloy foil material, the high Fe ingredient design is favorable to forming a great amount of fine dispersed Al3Fe second phase; La element is added into aluminum alloy to refine grains, and the Al3Fe phase is balled and separation of AlFeLa phase is promoted. The aluminum alloyfoil material prepared by controlling the addition of alloy elements by adopting the processing process has tensile strength of 143-166MPa and ductility of more than 2.5 percent in a cold-rolled state, the tensile strength of 81MPa, ductility of over 20 percent, erishen value of over 5.8mm and conductivity of 59-61 percent IACS in an annealing state, so that the comprehensive performance of an aluminum alloy foil material can be effectively improved, and the application field of aluminum foils can be enlarged.

Description

technical field [0001] The invention relates to the field of aluminum alloys, in particular to a high-performance ternary aluminum alloy foil material added with rare earth La and a manufacturing method thereof. Background technique [0002] Aluminum foil has the advantages of high specific strength, excellent barrier performance, shading, good formability, anti-corrosion, non-toxic and tasteless, etc. It is often used as packaging materials, electrolytic capacitor materials and heat insulation materials for buildings, vehicles, ships, houses, etc. field. [0003] my country's aluminum foil consumption is increasing year by year, from 300,000 tons in 2001 to about 1.3 million tons in 2010, and then to 3.52 million tons in 2015. At present, my country is the world's second largest consumer of aluminum foil after the United States, and the aluminum foil market has a large room for growth. With the development of the aluminum foil industry and the expansion of application fie...
