Problems solved by technology

However, the Mg content of the above-mentioned 5-digit series alloys is relatively high. Although good strength properties can be obtained, it also leads to high parameters such as rolling force during the rolling process, and it is difficult to control parameters such as rolling force during the actual rolling process. , leading to processing difficulties and high costs, affecting market share and promotion of use

Abstract

The invention relates to a blind aluminum alloy and a preparation method hereof; the materials comprise Al, Si, Fe, Cu, Mn, Mg, Zn, Ti and other impurities; the weight percents of the components are as follows that 0.1 percent to 0.6 percent of Si, 0.1 percent to 0.8 percent of Fe, 0.05 percent to 0.25 percent of Cu, 0.8 percent to 1.5 percent of Mn, 0.8 percent to 1.3 percent of Mg, no more than0.25 percent of Zn, no more than 0.1 percent of Ti, the single weight content of other impurity is not more than 0.05 percent and the total weight content of other impurities is not more than 0.15 percent and the rest is aluminum. The blind aluminum alloy and the preparation method of the invention have the following advantages that the product function is stable and the index meets the standard requirements of the blind aluminum material; the tensile strength and extension rate are comparatively high and the board shape and the quality of the board surface are good; the processing is comparatively easy and the cost is low; moreover, the recovery rate of the scrap is high.

Description

technical field [0001] The invention relates to an aluminum alloy material and a preparation method thereof, and more specifically, the invention relates to an aluminum alloy material for shutters and a preparation method thereof. Background technique [0002] As people's living and home styles become more and more diverse, blinds products that can keep pace with plastic curtains and cloth curtains are gradually occupying and expanding their market. The advantage of blinds is that they can adjust the incident angle of light, resist part of the ultraviolet rays, and make the natural light in the room full of changes. [0003] At present, the blinds on the market are mainly made of aluminum alloy, color steel, and PVC. Aluminum alloy is favored by the market because of its high hardness, light weight, non-aging, beautiful and practical after color coating, and the market demand is growing. However, the processing hardness of traditional louver aluminum alloy is too high, the ...
