Abstract

The invention relates to the technical field of hubs, in particular to an Al-Mg-Si aluminum alloy material for a spinning hub and a method for preparing the spinning hub through the Al-Mg-Si aluminum alloy material. The Al-Mg-Si aluminum alloy material for the spinning hub comprises, by weight, 2.00-5.80% of Mg, 0.25-0.50% of Si, 0.35-0.60% of Mn, 0.35-0.5% of Fe, 0-0.07% of Cu, 0.25-0.35% of Cr, 0.16-0.25% of Zn, 0.12-0.20% of Ti, and the balance Al and inevitable impurities. The Al-Mg-Si aluminum alloy material for the spinning hub is aluminum alloy which cannot be subjected to heat treatment strengthening; the prepared aluminum alloy hub does not need high-temperature long-time solid solution and aging treatment, the production process of the aluminum alloy hub can be simplified, the production efficiency is improved, energy consumption can be reduced, and resource pressure is relieved.

Description

technical field [0001] The invention relates to the technical field of wheel hubs, in particular to an Al-Mg-Si series aluminum alloy material for spinning wheel hubs and a method for preparing spinning wheel hubs with the aluminum alloy material. Background technique [0002] In recent years, the number of automobiles in my country has continued to rise. The development of the automobile industry not only brings comfort and convenience to human travel, but also has many adverse effects on the living environment, resource consumption and human health. As more and more people pay attention to environmental protection and energy conservation, automobile lightweight has become a major strategic goal for the development of the automobile industry today. Aluminum alloy has the advantages of low density, high specific strength, good corrosion resistance, good formability and rich content of aluminum in the earth's crust, and is favored by more and more automobile manufacturers. ...
