Abstract

The invention belongs to the technical field of aluminum alloy processing, and relates to a process for reducing the recrystallization temperature of 3003 aluminum alloy. The aluminum alloy raw materials are: Si: 0.12-0.20%, Fe: 0.5-0.6%, Cu: 0.08-0.12%, Mn: 1.05~1.2%, Mg≤0.023%, Cr≤0.023%, Zn≤0.1%, Ti: 0.005~0.018%, single impurity ≤0.05%, total impurity ≤0.15%, the balance is Al, by improving 3003 aluminum alloy casting The homogenization process of the ingot reduces the recrystallization temperature of the 3003 aluminum alloy plate and strip, eliminates the adverse effects caused by uneven grain structure, improves the surface quality of the plate and strip, saves production costs, and improves enterprise benefits.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy processing and relates to a process for reducing the recrystallization temperature of 3003 aluminum alloy. Background technique [0002] The 3xxx series aluminum alloy is an aluminum alloy with Mn as the main alloying element, which belongs to the aluminum alloy that cannot be strengthened by heat treatment. It has good welding performance, high plasticity, higher strength than 1xxx series aluminum alloys, and similar corrosion resistance to 1xxx series aluminum alloys. It is an aluminum alloy with good corrosion resistance and medium strength. Among them, 3003 aluminum alloy is the most widely used anti-rust aluminum. It is often used in welding parts of vehicles, aircraft and ships, as well as the outer packaging of products, especially in humid and corrosive environments. 3003 aluminum alloys for different purposes have different requirements for their microstructure and properties due ...
