By the First World War, aluminium began to also constitute the body of airplanes, replacing materials such as wood and canvas
The first fully metal plane, the Junkers J 1, was designed by German aircraft designer Hugo Junkers in 1915, with aluminium alloy tubing in its internal structure
×Aircraft grade aluminum is a term that refers to aluminum alloys that are used in aviation industry. They have light weight, high strength, corrosion resistance, and good mechanical and processing properties. They also perform well at low or high temperatures. The main aircraft grade aluminum alloys are 2000 series and 7000 series, such as aluminum 2024 and aluminum 7075. These alloys are often used to build the wings and fuselage of aircraft.,Grade 2024-T3 is the most common high-strength aluminum alloy. It is often considered aircraft quality. It has excellen…
Type of aluminium-zinc alloy
7075 aluminium alloy (AA7075) is an aluminium alloy with zinc as the primary alloying element. It has excellent mechanical properties and exhibits good ductility, high strength, toughness, and good resistance to fatigue. It is more susceptible to embrittlement than many other aluminium alloys because of microsegregation, but has significantly better corrosion resistance than the alloys from the 2000 series. It is one of the most commonly used aluminium alloys for highly stressed structural applications and has been extensively used in aircraft structural parts.

Chemical element, symbol Al and atomic number 13
Aluminium is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals; about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, nonmagnetic and ductile. It has one stable isotope: 27Al, which is highly abundant, making aluminium the twelfth-most common element in the universe. The radioactivity of 26Al is used in radiometric dating.
\nAluminium–copper alloys (AlCu) are aluminum alloys that consist largely of aluminum (Al) and traces of copper (Cu) as the main alloying elements. Important grades also contain additives of magnesium and silicon, often manganese is also included to increase strength. The main area of application is aircraft construction. The alloys have medium to high strength and can be age-hardened. They are both wrought alloy. Also available as cast alloy. Their susceptibility to corrosion and their poor weldability are disadvantageous.
\nAluminium–magnesium–silicon alloys (AlMgSi) are aluminium alloys—alloys that are mainly made of aluminium—that contain both magnesium and silicon as the most important alloying elements in terms of quantity. Both together account for less than 2 percent by mass. The content of magnesium is greater than that of silicon, otherwise they belong to the aluminum–silicon–magnesium alloys (AlSiMg).
Aluminium–silicon alloys or Silumin is a general name for a group of lightweight, high-strength aluminium alloys based on an aluminum–silicon system (AlSi) that consist predominantly of aluminum - with silicon as the quantitatively most important alloying element. Pure AlSi alloys cannot be hardened, the commonly used alloys AlSiCu and AlSiMg can be hardened. The hardening mechanism corresponds to that of AlCu and AlMgSi. The rarely used wrought alloys in the 4000 series and the predominantly used cast alloys are standardised in the 40000 series.
Aluminium metal is very rare in native form
History of the chemical element aluminium
Aluminium metal is very rare in native form, and the process to refine it from ores is complex, so for most of human history it was unknown. However, the compound alum has been known since the 5th century BCE and was used extensively by the ancients for dyeing. During the Middle Ages, its use for dyeing made it a commodity of international commerce. Renaissance scientists believed that alum was a salt of a new earth; during the Age of Enlightenment, it was established that this earth, alumina, was an oxide of a new metal. Discovery of this metal was announced in 1825 by Danish physicist Hans Christian Ørsted, whose work was extended by German chemist Friedrich Wöhler.
