Abstract

The invention discloses a 6A02 aluminum alloy round ingot. The aluminum alloy material is composed of, by weight percentage, 0.35-0.5% of Cu, 0.6-0.75% of Mg, 0.2-0.3% of Mn, >/=0.25% of Fe, 0.65-1.0% of Si, </=0.15% of Zn, </=0.15% of Ti, </=0.1% of other total, and the balance Al, and the total is 100%. A production process of the 6A02 aluminum round ingot includes steps of burdening, smelting, refining, casting and cast rod examining. The technical scheme further determines component parameters of the 6A02 aluminum alloy round ingot within a national standard range, reduces content of Zn and Fe elements, and can lower brittleness of castings, improve cracking resistance and reduce tendency, produced aluminum alloy is high in plasticity and good in anticorrosion performance.

Description

technical field [0001] The invention relates to a 6A02 aluminum alloy round ingot and a production process thereof, belonging to the technical field of nonferrous metal processing. Background technique [0002] Aluminum is an extremely abundant metal element on the earth, and has high specific strength and elastic modulus, high electrical conductivity and high thermal conductivity, and excellent corrosion resistance. In 1921, the world's aluminum output was 203,000 tons, in 1988 it reached 17.8 million tons, and in 2003 it reached 24 million tons. The scale of my country's aluminum industry ranks third in the world, with an annual production capacity of 4 million tons of electrolytic aluminum. Aluminum has become the second largest metal material after steel in my country, and it plays an increasingly important role in modern national life. However, my country's per capita aluminum consumption is only 1 / 20 of that of the United States, and 70%-80% of high-performance alumi...
