Abstract

The invention relates to the technical field of aluminum alloy and discloses a poured thermal-insulation aluminum alloy section which is prepared from raw materials: by weight percent, 1.0-3.0% of Mg,0.4-1.0% of Si, 0.4-1.6% of Gu, 0.8-1.0% of As, 0.2-0.6% of Ti, 0.4-1.0% of Mn, 1.0-3.0% of Fe, 0.4-0.6% of Cr, 0.4-0.6% of Zn and the balance being aluminum and some inevitable impurity. Si and Mg added both have age hardening capacity during processes such as solution strengthening and painting baking, which makes the aluminum alloy plates having bending workability such as extrusion forming capacity and curring capacity, and improves thermal insulation of the aluminum alloy plates. As Cr and Zn added both generate disperse particles during homogenization heat treatment, the disperse particles have effect of obstructing crystal boundary migration after recrystallization, and the fusion material is increased as generation of superfine crystal grains of the aluminum alloy structure; thus,good thermal insulation and high practicability are both achieved, and most casualties caused by accidents can be avoided effectively.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to a glue-injected heat-insulating aluminum alloy profile and a production process thereof. Background technique [0002] Aluminum is the second largest metal material in output after steel. Due to its good performance, wide application, large demand, and low recycling cost, it is known as "universal metal". Statistics show that there are 124 industries in my country. 113 industries use aluminum products, and the industrial correlation is as high as 91%. Therefore, the aluminum industry is one of the important pillar raw material industries for the sustainable development of the national economy. [0003] In recent years, with the rapid development of the economy, more and more alloy materials have been used, and the use of aluminum alloys is particularly extensive. Now there are various aluminum alloy materials on the market. As far as the current use of aluminum alloys is c...
