Abstract

The invention belongs to the technical field of formulas and preparation of aluminum alloy materials, and discloses a 6XXX series aluminum alloy round cast ingot. The 6XXX series aluminum alloy roundcast ingot is prepared from the following components in parts by weight: 0.60-0.65% of Si, less than or equal to 0.25% of Fe, less than or equal to 0.05% of Cu, less than or equal to 0.05% of Mn, 0.50-0.55% of Mg, less than or equal to 0.05% of Cr, less than or equal to 0.05% of Zn, less than or equal to 0.05% of Ti and the balance of Al. The invention further discloses a production method of the6XXX series aluminum alloy round cast ingot. The production method comprises the steps of material supplementing, smelting, casting and homogenizing. Compared with the prior art, the production methodhas the advantages that by optimizing the alloy composition and adding a small amount of Mg and Si auxiliary materials in the production process, an aluminum alloy has low quenching sensitivity, thecontrol difficulty of section deformation of a section on a production site is reduced, the quality of the section is improved, and the comprehensive performance requirement of an aluminum template for construction is met.

Description

technical field [0001] The invention belongs to the technical field of formulation and preparation of aluminum alloy materials, and in particular relates to a 6XXX series aluminum alloy round ingot and a preparation method thereof. Background technique [0002] At present, most of the aluminum alloy templates used in the construction market are made of extruded 6063 or 6061 alloy. 6063 aluminum alloy has excellent processability and quenching performance, which can improve production efficiency and low production cost, but the mechanical properties of this aluminum alloy are not high; The production cost of the 6061 round ingot is high, and the quenching sensitivity of the alloy is high, resulting in a complex production process and low production efficiency. At the same time, the two kinds of aluminum alloys are produced according to the traditional process, the corrosion resistance is not high, and the tensile strength and yield strength are weak, which limits the performa...
