Problems solved by technology

Due to the high production cost of my country's construction 6063 aluminum profile products and the great gap between product quality and process technology, most of the profiles in my country are concentrated in low-end products. It is difficult to produce profiles with complex cross-sections for 6063 aluminum profiles, which makes the scope of application of the products narrow.

Abstract

The invention discloses a novel 6063 aluminum alloy material. Rare earth elements are added into the original 6063 aluminum alloy. The novel 6063 aluminum alloy material comprises, based on the weight percentage,0.36%- 0.4% of Si, 0.48% - 0.52% of Mg, 0 -0.35% of Fe, 0 -0.1% of Cu, 0 - 0.05% of Mn, 0 - 0.05% of Cr, 0 - 0.05% of Zn, 0 - 0.05% of Ti, 0.18%-0.22% rare earth elements, 0-0.1% of the remaining impurities and the balance of Al. According to the invention, the content of Mg and Si is controlled within a narrow range. At the same time, cerium-based mixed rare earth elements and alloying element boron are added, which keeps alloy material high strength and high electrical and thermal conductivity; improves machining property and plastic extrusion; and improves production efficiency.

Description

technical field [0001] The invention relates to a novel 6063 aluminum alloy material, which belongs to the technical field of nonferrous metal processing. Background technique [0002] The widening application of 6063 aluminum alloy in construction, decoration, automobile, aviation, electronics and other fields has higher requirements for the strength performance, corrosion resistance and oxidation coloring performance of the new modified deformed aluminum alloy. Due to the existence of a large number of hard phases in some aluminum alloys, the machining performance is poor, the extrusion force is large, the die wear is large, the life is low, the extrusion speed is slow, the production efficiency is low, and the energy consumption is high. For some thin-walled and complex profiles, especially extruded profiles with a width-to-thickness ratio greater than 100 and a large degree of asymmetry and anisotropy, ordinary 6063 alloys cannot be formed well at all. In order to meet m...
