Concepts and definitions of aircraft aluminium alloys and aircraft aluminium sheets

Today we are going to talk about the concepts and definitions of aircraft aluminium alloys and aircraft aluminium sheets. Aluminium, magnesium, titanium and other metals are less dense and are often referred to as light metals. The corresponding aluminium, magnesium and titanium alloys are called light alloys. The special excellent performance and development potential of light alloys have prompted countries around the world to pay more and more attention to the research, development and promotion of the application of light alloy materials. Today, the editors of Haomei Aluminium take you to understand aircraft aluminium alloys and aircraft aluminium sheets.

First of all, let's take a look at the concept and definition of aerospace aluminium alloy. Aerospace aluminium is a kind of ultra-high strength deformed aluminium alloy, which is now widely used in the aviation industry. Compared with ordinary aluminium alloys, aircraft aluminium alloys have higher requirements for strength, hardness, toughness, fatigue resistance and plasticity. Aviation aluminium alloy has better mechanical and processing properties, good plasticity after solid solution treatment, good heat treatment strengthening effect, generally high strength below 150°C (or even higher), good toughness, and is an ideal material for aviation structure. The performance of pure aluminium cannot meet the requirements of use in most occasions. For this reason, people add various alloying elements to pure aluminium to produce aluminium alloys that meet various properties and uses. With good thermal conductivity, easy forming and low prices, aluminium alloys have been widely used in aerospace, transportation, light industry and building materials, communications and electronics. There are various aluminium alloys used in aircraft. Today, the world's aircraft aluminium alloys structure with aluminum alloy is mainly high strength 2 series (2024, 2017, 2A12, etc.) and ultra-high strength 7 series (7075, 7475, 7050, 7A04, etc.), in addition to some 5 series (5A06, 5052, 5086, etc.) and 6 series (6061, 6082, etc.) and a small amount of other series of aluminum.

As for the aircraft aluminium sheets, it is an aluminium sheet manufactured from the aircraft aluminium alloys described above. Its high hardness and strength, good corrosion resistance and light weight make it a high-end aluminium sheet ideal for use in the aerospace sector.
