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...

Examples

Embodiment 1

[0033] A new type of Al-Mg alloy, the proportion of each element in the Al-Mg alloy is: Mg: 0.8%; Si: 0.14%; Fe: 0.14%; Cu: 0.03%; Mn: 0.02%; Zn: 0.02% ; Ti: 0.02%; Al: balance.

[0034] The technical effect of this embodiment 1 is as follows:

[0035] 1. After polishing and oxidation, this new type of aluminum material has the same surface brightness as pure aluminum material, and because of its high Brinell hardness, tensile strength and yield strength, it can be widely used in the interior and exterior of automobiles. The decorative parts not only maintain a good bright effect, but also ensure the service life of the decorative parts.

[0036] 2. This new type of aluminum material has good tensile strength, yield strength, and hardness at the same time, and its mechanical strength is similar to that of the 5-series aluminum plate. Figure 1-Figure 3 It is a graph of mechanical properties of pure aluminum, Al-Mg alloy, 5052H32 (Mg: 2.2 ~ 2.8) aluminum plate (the measured v...

Embodiment 2

[0038] A new type of Al-Mg alloy, the proportion of each element in the Al-Mg alloy is: Mg: 1.0%; Si: 0.14%; Fe: 0.14%; Cu: 0.03%; Mn: 0.02%; Zn: 0.02% ; Ti: 0.02%; Al: balance.

[0039] The technical effect of this embodiment 2 is basically similar to that of embodiment 1, except that by controlling the addition ratio of Mg, the yield strength of the aluminum alloy can be increased, while maintaining the good brightness of pure aluminum, and the surface gloss is less reduced after anodic oxidation The advantages.

[0040] The above-mentioned inventive materials can be applied to the manufacture of interior and exterior trim parts of automobiles, such as sill panels, bright trim strips, signs and the like. Take the door sill pedal of a car as an example: First, the aluminum plate is processed into a mirror surface after being machine-polished or electro-polished; Process, processed into products; finally, after chemical polishing, light emitting, anodizing, sealing and other...
