What materials are used in Boeing aircraft?
Materials Used in Boeing Structures Boeing employs a combination of materials in its aircraft structures: Aluminum Alloys: The most common material, offering high strength-to-weight ratio and 1. Composite Materials: Used increasingly in newer models for weight savings and fatigue 2. Likewise, steel is stronger than aluminum, but weighs significantly more. Steel is only used in aircraft when extremely high strength is needed, such as landing gears, or extremely high-speed planes.Carbon fibre is stronger per unit weight than steel. In strength-to-weight ratio, it is five times lighter and hence five times stronger than steel.Still one of the world’s most popular jet planes, the Boeing 737 is approximately 80 percent aluminum, with different alloys used for different parts of the aircraft.
