Novel aluminum alloy plate as well as preparation method and application thereof

Abstract

The invention relates to a novel aluminum alloy plate as well as a preparation method and an application of the novel aluminum alloy plate. The novel aluminum alloy plate is made from an Al-Mg alloy and is characterized in that the Al-Mg alloy comprises the following elements in percentage by weight: 0.8-1.0 percent of Mg, 0.14 percent of Si, 0.14 percent of Fe, 0.03 percent of Cu, 0.02 percent of Mn, 0.02 percent of Zn, 0.02 percent of Ti and the balance of Al. According to the novel aluminum alloy plate disclosed by the invention, with the adoption of the Al-Mg alloy, good surface performance of pure aluminum is kept, and the pure aluminum also has good mechanical properties such as tensile strength and rigidity; and the novel aluminum alloy plate is particularly suitable for manufacturing inner and outer decorations of vehicles, such as sill plates, lighting trims and labels.

Description

technical field [0001] The invention relates to an aluminum alloy plate, in particular to a novel aluminum alloy plate and its preparation method and application. Background technique [0002] With the continuous development of the industry, due to its low density, good corrosion resistance, weather resistance, low temperature resistance, non-magnetic, and good surface properties, aluminum is widely used in aviation, aerospace, navigation, automobiles, machinery manufacturing, and Japan. It has been widely used in many fields such as style. Such as: car door sill panels, bright trims, signs, lampshades, etc. These parts must not only have good mechanical properties such as tensile strength, yield strength, and hardness, but also have good surface properties as decorative parts, that is, after the aluminum plate is polished and oxidized, the surface brightness cannot be reduced much. The pure aluminum plate has a brighter surface after chemical polishing, light emitting, an...

AI Technical Summary

Problems solved by technology

The pure aluminum plate has a brighter surface after chemical polishing, light emitting, anodic oxidation sealing and other processes, and the decorative effect is better, but because the pure aluminum plate is soft, it is easy to scratch or deform, so the application is greatly limited; the general aluminum alloy The mechanical properties are very good, but after surface treatment such as polishing and oxidation, the surface brightness drops a lot, so when used as an ornament, the decorative effect is greatly reduced, and its application is also greatly restricted.
