super sonic planes are made of titanium
normal planes are usualy made of aluminium alloys like duralumin (Al/Mg/Cu) and Magnalium (Al/Mg)
These alloys are used because pure Al is light but not very strong while the alloys are light yet really strong.

Virtually all metals used in aircraft are alloys of some type, for instance Titanium, used where light weight and enormous strength and heat resistance is required, is usually alloyed with about 6% Vanadium. In the case of Titanium, this actually allows the metal to be heat treated somewhat better than the pure metal is able to be and results in a stronger component because of this. Duralumin, the common name for AA2024 aluminium used in aircraft, (although they no longer use the original Duralumin recipe), is an alloy of about 94% Aluminium and the balance is Magnesium, Copper and Manganese. This makes the aluminium stronger, more fatique resistant and far harder

It depends on the aircraft's part (in question). Usually you'll find materials which include: Aluminium, Titanium, Fibre glass (on planes like Dornier 228 turboprop's wingtips), Carbon Fibre, composites, alloys such as the one called "7055" which Boeing uses for the upper skin of the 777 airliner's wings resisting stresses and bending, etc. Theres a wide range of materials (notice that I'm saying materials not metals).

The metal for aircraft manufacture needs tobe light to save on weight and operation cost.At the same time it needs to be strong.
Nowadays most aircrafts are made of an alloy of aluminium called Duralumin.
This is an alloy of aluminium+magnesium+copper. It is as light as aluminium but much stronger.
Titanium and its alloy is being used in a limited experimental stage. Titanium is as light as aluminium and stronger than steel but vey expensive.

well it depends on the type of aircraft. some aircraft have a steel frame(chromoly steel 4130) that is covered with fabric like a Piper Cub.
But on larger aircraft the skins and bulkheads are generally an aluminum known as 2024-T3.
Other aluminums such as 6061-T6 may also be used in the form of tubes or extruded angles for brackets or linkage.
Almost all planes use steel for the landing gear. Chromoly is popular here too. 4130 is a popular grade of Chromoly.

Aircraft aluminum, in various alloys such as 2024 and 7075. Areas of high stress or high temperatures use stainless steel or titanium. a combination of these materials can be used depending upon application. Landing gear are made of "High-Tuff" steel on the heavies. US manufacturers use an alclad aluminum as a corrosion preventative along with fluid resistant primers. Rod ends and hardware can vary, but they are mostly cad plated steel. Most rivets are aluminum, varying in hardness. Bracketry can be aluminum or magnesium. Hydraulic lines can be steel, steel braided rubber, aluminum, etc. Wiring can be copper, copper clad, etc

the skins on helicopters is aluminum. Just about all aircraft use aluminum because it's light and strong. When it comes to frames, sometimes the metal is little more exotic. Some components on our helicopters is magnesium and titanium.

Mostly aluminum alloys. Titanium is only used sparingly, as it's very expensive. Examples are Cockpit shell for the A10 for protection from small arms, and the bulkhead behind the cockpit of the F22. We even have a bit on the C130, especially fasteners.

Light weight and high strength are important in aircraft. The most common material used is aluminum, but titanium, magnesium, wood and doped fabric, and even steel have been used for airframes.

Aircraft Aluminum. Its a special lightweight chemical makeup.

Most airframes are made of aluminium or aluminium alloys such as duralumin. Other lightweight metals and other materials are now increasingly being used, such as titanium and titanium alloys, magnesium, kevlar, carbon fibre, boron fibre and various other plastics and composites.
As an example, The Grumman F14 Tomcat airframe was 25% Titanium and also included aluminium, stainless steel, boron fibre and other composites
