Because it is a strong metal and can withstand the tremendous temperatures created the jet engine.
Steel, titanium and aluminium are all used in jet engines.
If you are asking about carburetor jets, then they are made from brass. Jet engines, are made with many different materials, the main one probably is titanium.
Its amazing like one direction
jet engines
The jet engines used jet fuel, not gasoline as the 6 main engines did.
Usually forged steel. On racing engines sometimes titanium or other alloy.
Piston engines are usually Steel, but there are some with major parts of aluminum alloy. Jet engines are made of steel, aluminum and titanium alloys. Each of these type metals have a variety of alloys that have different properties, such as strength, heat resistance and fatigue strength. A design engineer will select the alloy that provides him the properties that he needs for the application.
Titanium would likely be the better choice for a stealth jet due to its lightweight, strong, and corrosion-resistant properties. Platinum is heavier and more expensive, making it less practical for use in aircraft construction.
Jet engines are made of fans, they get smaller and smaller as the jet gets deeper... U know how jets are big at one end and small at the other? That's because the fans get smaller and what it does is the air condenses and escapes at a great force through the other side.
An aircraft propelled by jet engines rather than piston engines.
Different Materials like metal and Fiber Glass
They did not have good metallurgy by the time they went into production.
