* Aluminium alloy: The airframe was made of aluminium alloy, with some steel and wood components. The specific alloy used was Duralumin, which is a strong and lightweight aluminium alloy that is also resistant to corrosion.
* Steel: Steel was used for some of the structural components of the Spitfire, such as the landing gear and the main spar.
* Wood: Wood was used for some of the non-structural components of the Spitfire, such as the propeller blades and the tail surfaces.
Other materials:
* Fabric: Fabric was used to cover the wings and tail surfaces of the Spitfire. The fabric was doped with a mixture of cellulose nitrate and castor oil to make it taut and weatherproof.
* Glass: Glass was used for the windscreen and the canopy of the Spitfire. The glass was laminated to make it more resistant to damage.
* Rubber: Rubber was used for the tires and the fuel tanks of the Spitfire. The rubber was vulcanized to make it more durable.
* Paint: Paint was used to protect the Spitfire from corrosion and to give it a camouflage pattern.
The Spitfire was a complex aircraft that was made of a variety of materials, but the primary material used was aluminium alloy.
