Other metals commonly used in airframe structure, such as nonclad high strength aluminum alloys, steel, and magnesium alloys, require special preventive measures to guard against corrosion. a. Aluminum alloys, for example, are usually anodized (a chemical coating), or in some later generation aircraft an aluminum applied plating (ion vapor disposition (IVD)), then primed and possibly topcoated
Copper is one of the most versatile pure metals. Evidence of copper dates back to 8700 BC but commercial production wasn’t underway until the 20th century. Being a pure metal, copper is usually paired with another metal to create alloys but it is also used by itself in aviation. but it is also used …
Typically used in aircraft structural parts. 7075 is one of the highest strength, commercially available alloys with fair corrosion resistance and machinability. 7175 is basically the high purity version of 7075 with tighter control on the iron and silicon for an increase in strength and toughness.
9/1/2015· Today the new alloys and associated corrosion protection systems are used extensively in helicopter and fixed wing military aircraft, including the Westland Lynx, …
Aluminum alloys are widely used on aircraft because of their light weight and high strength-to-weight ratio. Often these alloys contain different concentrations of copper, zinc, magnesium and other elements in order to achieve the desired mechanical
4/12/2011· Pure magnesium is soft and extremely flammable/explosive. It is very light though, so it is ideal for aircraft parts when used in an alloy. The chemical equation would depend on …
The lightweight construction and excellent insulation properties of magnesium die casting alloys make them an ideal choice for using in spacecraft, missiles, and aircraft. In addition, most of the magnesium die casting alloys are also highly durable, which means that can be used in low-temperature, low oxygen, and high altitude flight.
It is the basis of strong, light alloys used in the aircraft and automobile industries (e.g. in engine asselies). Alloys with zirconium and thorium have also been investigated for their use in aircraft manufacture. Pure magnesium can also be used as a sacial
The main reason why magnesium is used “sparingly” in modern aircraft, typically less than 1% of the structural mass of large passenger aircraft, is poor corrosion resistance. Magnesium was originally used in aircraft during the 1940s and for the next thirty years was a common structural material.
Alloys for aerospace industry must coine high performance regarding mechanical properties and corrosion resistance. A review is given here on the use of magnesium in aircrafts in the past. The paper then presents requirements of modern aircraft industry

An aircraft, even though made of the best materials and strongest parts, would be of doubtful value unless those parts were firmly held together. Several methods are used to hold metal parts together; they include riveting, bolting, brazing, and welding. The process
1000 series are essentially pure aluminium with a minimum 99% aluminium content by weight and can be work hardened. 2000 series are alloyed with copper, can be precipitation hardened to strengths comparable to steel. Formerly referred to as duralumin, they were once the most common aerospace alloys, but were susceptible to stress corrosion cracking and are increasingly replaced by 7000 series
25/6/2019· Over half of all magnesium is used in alloys with aluminum, which are valued for their strength, lightness, and resistance to sparking, and are widely used in automobile parts. In fact, various car manufacturers use cast magnesium-aluminum (Mg-Al) alloys to produce steering wheels, steering columns, support brackets, instrument panels, pedals and inlet manifold housings, among numerous …
Use of Magnesium in Airplane Cabins—Updated 11/15 Based on requests from industry, and considering the absence of recent research data, the FAA has worked extensively with industry to evaluate the potential use of magnesium alloys in airplane cabins.
24/11/2019· Magnesium is the eighth most common element in the universe and the Earth''s crust. It has a wide range of uses in industry and is also an important element in medicines. It is often used as an alloy with aluminum; the addition of magnesium lightens the weight of
METALLIC MATERIALS The most common metals used in aircraft construction are aluminum, magnesium, titanium, steel, and their alloys. Alloys An alloy is composed of two or more metals. The metal present in the alloy in the largest amount is called the base metal..
Why make alloys? Many pure metals are too soft for many uses. They can be made harder by adding another element to the pure metal, so forming an alloy. This explains why an alloy often has more
Magnesium (Mg) 5xxx - The addition of magnesium to aluminum increases strength through solid solution strengthening and improves their strain hardening ability. These alloys are the highest strength nonheat-treatable aluminum alloys and are, therefore, used
That is why magnesium alloys feature additions of other metals. These additions increase magnesium’s strength and makes it a more viable commodity. Magnesium is most commonly used in conjunction with aluminum, but there are magnesium alloys that possess other metals, as well.
Aircraft manufacturers use high-strength alloys (principally alloy 7075) to strengthen aluminum aircraft structures. Aluminum alloy 7075 has Copper (1.6 %), Magnesium (2.5 %) and Zinc (5.6 %) added for ultimate strength, but the copper content makes it very difficult to weld.
METALLIC MATERIALS The most common metals used in aircraft construction are aluminum, magnesium, titanium, steel, and their alloys. Aluminum Aluminum alloys are widely used in modern aircraft construction. Aluminum alloys are valuable because they have a high strength-to-weight ratio.
Primary Uses. The higher-strength 2xxx alloys are widely used for aircraft (2024) and truck body (2014) appliions, where they generally are used in bolted or riveted construction. Speciﬁc meers of the series (e.g., 2219 and 2048) are readily joined by gas metal
Seaplanes used special, corrosion resistant alloys which were needed in the marine environment. In the end, however, this is still outweighed by the principal advantage of aluminium: Its low density. This allows to use thicker gages for the same weight, so the buckling strength of aluminium skins is far better than that of equally heavy steel skins.
Our alloys compare favorably to other materials and magnesium alloys on the market. But only ALLITE ® SUPER MAG TM has flame retardancy that allows it to melt, instead of burn, under a 1200° F flame.
After the very earliest days of manned flight, the excellent strength to weight ratio of aluminium have made it the prime material for the construction of aircraft. These same properties of aluminium mean various alloys are now also used in passenger and freight rail cars, commercial vehicles, military vehicles, ships & boats, buses & coaches, bicycles and increasingly in motor cars.
