Abstract

The invention discloses an aluminum alloy for manufacturing automobile sunroof guide rails and a production process thereof, wherein the aluminum alloy comprises the following raw materials in proportions by weight: Si 0.25-0.31%, Fe≤0.15%, Cu≤0.05%, Mn 0.03 ~0.09%, Mg 0.47~0.53%, Zn≤0.05%, Ti≤0.05%, single impurity≤0.05%, total impurity≤0.15%, and the balance is Al. As far as automotive sunroof products are concerned, they have strict requirements on the mechanical properties of aluminum profiles, such as hardness requirements of 9.5-11.5HW and yield strength requirements of 120-160Mpa. The invention can well stabilize the hardness and yield strength of skylight products within the above range through specific formula and specific process. In actual production, the automotive sunroof guide rail profile can be obtained through one-time processing and bending, which improves the bending efficiency of the sunroof, and the product arc can reach within a tolerance of 0.4mm, completely avoiding the previous aluminum profile screening process and eliminating the need for profiles in the In case of cracking during processing, there is no need to adjust the stamping process according to the hardness of the product, which improves the efficiency of the production line by more than 20%.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing and manufacturing, and in particular relates to an aluminum alloy for manufacturing automobile sunroof guide rails and a production process thereof. Background technique [0002] Yield strength is the yield limit of plastic deformation of metal materials. When the difference in yield strength is large, when the same stress is applied, the degree of plastic deformation of the material will be different, resulting in a deviation in the bending arc, which will lead to secondary stamping or product scrapping . Due to the inability to perform tensile tests on all products and the destructive nature of tensile tests, currently the products are generally classified by measuring the hardness of the product using Webster hardness and estimating the yield strength of the product using the Webster hardness value. Through this classification method, metal materials with different yield stre...
