Aluminium alloy section and manufacture method thereof

Abstract

The invention discloses an aluminium alloy section and a manufacture method thereof. The aluminium alloy section comprises the following elementary components of 87.5 percent of Al, 0.4 percent of Si, 1.1 percent of Fe, 0.75 percent of Mn, 0.8 percent of Mg, 2.1 percent of Zn, 4.4 percent of Cu, 0.1 percent of Ni and 0.1 percent of Ti. The manufacture method of the aluminium alloy section comprises the following process steps of: (1) melting an aluminium material, and adding metal components including the Si, the Fe, the Cu, the Mn, the Mg, the Zn, the Ni and the Ti; (2) controlling high temperature for casting to form an aluminium-based solid solution; (3) carrying out purification treatment and modification to enable grains to be refined and reduced to 1 / 20 before treatment and enable the total content to be reduced by 30 percent to obtain antirust hard aluminium alloy; and (4) splicing and molding by adopting a mould to obtain the aluminium alloy section. The aluminium alloy section provided by the invention has favorable corrosion resistance and excellent mechanical strength and is superior to a general section for a common laboratory.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to an aluminum alloy profile and a manufacturing method thereof. Background technique [0002] At present, most of the materials used in the laboratory furniture industry are steel materials, but a thin layer of plastic powder is coated on the surface to resist the special corrosive environment of the laboratory, but there are two defects: 1. Steel The material itself is not anti-corrosion, especially after contacting with oxygen, it will form iron oxide, which will accelerate the corrosion rate of Fe; 2. The inner wall of the steel pipe cannot be coated, and in the laboratory environment, acid and water vapor will enter the inner wall through various processing ports and cause corrosion. A chemical reaction occurs, especially during use, as long as there is a slight scratch on the surface, Fe will be exposed to corrosive air. As a result, the life of laboratory furniture i...

[0002] At present, most of the materials used in the laboratory furniture industry are steel materials, but a thin layer of plastic powder is coated on the surface to resist the special corrosive environment of the laboratory, but there are two defects: 1. Steel The material itself is not anti-corrosion, especially after contacting with oxygen, it will form iron oxide, which will accelerate the corrosion rate of Fe; 2. The inner wall of the steel pipe cannot be coated, and in the laboratory environment, acid and water vapor will enter the inner wall through various processing ports and cause corrosion. A chemical reaction occurs, especially during use, as long as there is a slight scratch on the surface, Fe will be exposed to corrosive air

As a result, the life of laboratory furniture is shortened, and it usually becomes rusty in 1-3 years. The country invests about 3 billion in laboratory construction every year, which will directly cause huge waste of national investment and even leave a serious safety hazard. Hidden danger
