Problems solved by technology

[0003] However, 5083 and 5182 alloys are mainly used in automobiles, ships, molds and other fields, and the market price of materials is relatively high. As aluminum alloys for shutters, the material cost of shutters is increased, and the overall price of shutters is increased. Universal use and promotion of aluminum alloy shutters
[0004] Moreover, 5083 and 5182 alloys are high-Mg aluminum alloys with Mg content ≥ 4.0%. The material has a high degree of work hardening. The production process requires high equipment capabilities, and it is difficult to control the shape of the plate. Surface defects such as oil spots are prone to occur. Yield is low
[0005] In addition, although the production process of 3003 alloy is simple, its mechanical properties are lower than those of 5083, 5182 and other aluminum alloys, and the tensile strength of H18 state is only about 200MPa

Abstract

The invention discloses an aluminum alloy for a louver and a preparation method of the aluminum alloy. The aluminum alloy is composed of the following components of 1.0-2.0% of Si, 0.3-0.7% of Fe, 0.25-0.5% of Cu, 0.9-1.3% of Mn, less than or equal to 0.5% of Mg, less than or equal to 1.0% of Zn, 0.05-0.15% of Ti, and the balance Al and inevitable impurities with the total amount being less than 0.15%. The aluminum alloy for the louver is moderate in work hardening degree and low in manufacturing difficulty; and the plate shape and the surface quality are easy to control, yield is high, and waste recycling degree is also high.

Description

technical field [0001] The invention relates to the field of aluminum alloys, in particular to an aluminum alloy for shutters and a preparation method thereof. Background technique [0002] Aluminum alloy shutters have the advantages of high-end, aesthetics and environmental protection, and are widely used as buildings and interior decorations. Aluminum alloy shutters were first popular abroad. Initially, aluminum alloys for shutters were made of 3003, 5052, 2024 alloys and other materials. With the further popularization and application of aluminum alloy shutters, higher requirements are put forward for the strength and cost of aluminum alloy shutters. At present, the commonly used aluminum alloy shutters mainly include 3003, 5083, 5182 and other alloys. [0003] However, 5083 and 5182 alloys are mainly used in automobiles, ships, molds and other fields, and the market price of materials is relatively high. As aluminum alloys for shutters, the material cost of shutters is...
