uses of metals on planes?

Question

what types of aircraft use titanium alloy and what part are they used for. and also aluminium.

Answer 1

many commercial airliners use titanium in landing gear systems, due to the high stresses they must endure. aluminum is the most common airplane skin material, though there are more and more using composites. aluminum is by far the most used metal on aircraft, except maybe copper wiring. for specific details, you'd need to contact a manufacturer

Answer 2

Titanium is used where high strength and hardness is required, like in some undercarriage and engine components... or the canon port(s) on a Panavia Tornado. Some aircraft parts use exotic alloys like Ti/Li/Mg/Al alloys. Aluminium is used throughout the structure, though composites of Kevlar and carbon fiber are starting to replace aluminium alloys in wing and body panels, though not yet in the underlying structures.

This is far from a 'complete' answer.

Answer 3

Titanium is expensive, and therefore not used for more mundane parts like skin and structural elements. It is frequently found in turbines though. The fan blades are almost always titanium, and some engines are shrouded with a weave of titanium and kevlar (kind of like a blanket) the both dampens noise and protects passengers in the event of an engine exploding and throwing fan blades towards the fuselage.

Answer 4

The new 787 dreamliner will be built with a composite and titanium alloy fuselage. One of the cool side-effects of titantium and composite will be reduced "jet lag" since titanium and the rest of the material in the composite doesn't corrode and require the same dry bleed air as 100% aluminum.

Answer 5

Beech started using titanium years ago on the Bonanza and then the Baron line. The light weight helped move the Center of Gravity forward; the metal was used in the tails.
