FAQs: Aircraft Wing Spars

Aircraft Wing spars are the main load-bearing structures in aircraft wings. They run from the root to the tip, distributing aerodynamic and structural loads while supporting critical systems like landing gear, flaps, and fuel tanks

Common materials include aluminum alloys (2024, 6061, 7075) for lightweight strength, titanium for high strength-to-weight and fatigue resistance, and advanced composites for optimized stiffness and reduced overall weight in modern aircraft.

Aluminum alloys offer a proven balance of strength, machinability, and corrosion resistance, making them ideal for both commercial and private aircraft where cost-effectiveness and performance are key.

Titanium is used in high-stress areas or military aircraft, where strength and fatigue resistance are more critical than weight or cost. It performs well under extreme conditions and provides superior longevity.

We employ 3-axis and 5-axis CNC machining, precision turning, grinding, and hybrid additive manufacturing to achieve tight tolerances and smooth finishes across all materials.

For critical structural areas, Zintilon maintains tolerances as tight as ±0.0001 inches, ensuring precision fit, alignment, and aerodynamic performance.

Yes, we offer rapid prototyping, low-volume manufacturing, and full-scale production for both metallic and composite wing spars, supporting commercial, private, and defense applications.

All parts are produced under AS9100D-certified quality systems, ensuring compliance with FAA, EASA, and military-grade specifications.

Depending on the material, finishes include anodizing (for aluminum), passivation (for titanium), and protective coatings (for composites) to enhance corrosion resistance, bonding, and fatigue life.

CNC machining ensures dimensional precision, consistent quality, and weight optimization, improving aerodynamics, fuel efficiency, and structural safety.
