Abstract

The invention discloses a corrosion-resistant and wear-resistant high strength electrophoretic aluminum profile and a preparation process thereof and belongs to the field of aluminum profile preparation. The corrosion-resistant and wear-resistant high strength electrophoretic aluminum profile is prepared from the following raw materials in percent by weight: 0.8-1.2% of Mg, 0.4-0.6% of Si, 0.2-0.4% of Ti, 0.22-0.3% of Fe, 0.06-0.1% of Cu, 0.08-0.12% of Zn, 0.06-0.08% of Cr, 0.12-0.18% of Mo and the balance of Al and inevitable impurities. The preparation process is simple and effective and convenient and rapid in process operation. By controlling the contents of Mg, Si, Fe, Cu and Zn reasonably, strengthening phases such as Al2Cu, Al2CuMg, Mg2Si, MgZn2 and the like are formed in the electrophoretic aluminum profile to strengthen the synergistic effect, refine crystals and improve grain distribution, so that performance, such as wear resistance and corrosion resistance, of the electrophoretic aluminum profile is improved. By matching Si, Ti, Fe, Cr and Mo, the grains are refined, the cast structure and the weld joint structure are refined, the recrystallization temperature is increased, the thermal stability of a material is improved, the intergranular corrosion is avoided, and the corrosion performance of the electrophoretic aluminum profile is improved.

Description

technical field [0001] The invention relates to the technical field of aluminum profile preparation, in particular to an anti-corrosion and wear-resistant high-strength electrophoretic aluminum profile and a preparation process thereof. Background technique [0002] Electrophoretic aluminum profile, the full name of electrophoretic coating aluminum profile, refers to a special type of aluminum profile that forms a paint protective film on the surface of ordinary original aluminum profiles after electrophoretic coating process. The above-mentioned ordinary original aluminum profile is supplemented with electric current to complete. [0003] At present, the aluminum profile industry lacks an efficient and convenient preparation process from the preparation of aluminum profile raw materials to the electrophoretic coating process, and the existing electrophoretic aluminum profiles have poor anti-corrosion and wear-resistant performance during use.
