Abstract

The present invention discloses a 6061 deforming aluminum alloy and production process thereof. Adding Aluminum-rare earth master alloy while 6061 aluminum alloy is melting. 6061 deforming aluminum alloy comprises, based on the weight percentage, 0.5%- 0.52% of Si, 0.19%- 0.21% of Fe, 0.8% - 0.9% of Mg, 0.28% -0.3% of Cu, 0.15% - 0.18% of Cr, 0.24% - 0.26% of Zn, 0.14% - 0.16% of Ti, 0.1% - 0.05% rare earth elements, 0-0.1% of the remaining impurities and the balance of Al. The sum percentage of the components is 100 %. The production process includes smelting, proportioning, melting, casting, extrusion molding and aging treatment. The invention improves the plasticity and formability of alloy in aluminum alloy by adding Aluminum-rare earth master alloy, thus reducing the amount of alloy elements and production cost.

Description

technical field [0001] The invention relates to a 6061 deformed aluminum alloy and a production process thereof, belonging to the technical field of nonferrous metal processing. Background technique [0002] 6061 aluminum alloy is a heat treatment strengthenable alloy with good formability, weldability, machinability, and medium strength. It can still maintain good operability after annealing. It has been widely used in aerospace fixtures, electrical fixtures, communication fields, automated mechanical parts, precision machining, mold manufacturing, electronics and precision instruments, SMT, PC board solder carriers, etc. [0003] 6061 (LD30) is Al-Mg-Si series wrought aluminum, the content of magnesium and silicon is slightly higher than that of 6063 (LD31), and it contains a small amount of copper, so its strength is higher than that of LD31. A small amount of chromium is added to offset the adverse effect of copper on corrosion resistance. Although the increase of allo...
