Abstract

The invention provides an aluminum alloy tube for a camping tent support and a preparation method thereof, relating to the aluminum alloy tube and the preparation method thereof. In order to solve the problem that the conventional camping tent support has poor mechanical properties and cannot meet the requirements of carrying more items in travel, the aluminum alloy tube for the camping tent support is prepared from the following components in percentage by mass: 0.05 to 0.30 percent of Si, 0.07 to 0.35 percent of Fe, 2.0 to 3.0 percent of Cu, 0.01 to 0.15 percent of Mn, 2.8 to 4.0 percent of Mg, 0.18 to 0.35 percent of Cr, 7.5 to 9.0 percent of Zn, 0.02 to 0.20 percent of Ti and 82.65 to 87.37 percent of Al. According to the preparation method, the content of other elements is controlled to form a novel aluminum alloy material by increasing the content of main reinforcement elements such as Zn and Cu, the mechanical properties are high, the tensile strength is greater than 700 MPa, and the non-proportional extension strength is greater than 600 MPa.

Description

technical field [0001] The invention relates to an aluminum alloy pipe material and a preparation method thereof, in particular to an aluminum alloy pipe material for a tourist tent support and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the tourism industry is increasingly prosperous. In order to improve the quality of tourism and carry more items for tourists, aluminum alloy materials are generally used to make tourist tent brackets to reduce the weight of tents and increase the number of other items carried by tourists. The current tourist tent bracket is made of 7001 aluminum alloy and 7075 aluminum alloy, the tensile strength is 560MPa, and the non-proportional extension strength is 505MPa. Its mechanical properties are low and cannot meet the requirements of carrying more items for tourism. Contents of the invention [0003] In order to solve the problem that the current tourist tent support has lo...
