Why Titanium Is Used in Aerospace

Titanium sits between aluminium and steel in the aerospace materials toolkit — and for many parts it beats both.

Strength-to-Weight

Titanium is about 45% lighter than steel at comparable strength, cutting weight without sacrificing structural integrity.

High-Temperature Capability

Many titanium alloys keep useful strength above 500°C, suiting engine components, exhaust and bleed-air systems where aluminium would fail.

Fatigue & Corrosion

• Excellent fatigue life for cyclically loaded parts
• Immune to salt-spray and most service fluids
• Galvanically compatible with carbon-fibre composites (unlike aluminium)

Typical Parts

• Airframe brackets, fittings and fasteners
• Landing-gear components
• Engine blades, discs and rings
• Hydraulic tubing

Common grades: Grade 5, 23, 9 and 5 for structure; CP grades for ducting.
