AMS 4940 - Commercially Pure Titanium Sheet
AMS 4940 is the SAE specification for commercially pure titanium sheet in the annealed condition. This specification covers the chemistry, mechanical properties, and testing requirements for unalloyed titanium sheet for aerospace and industrial applications requiring corrosion resistance and formability.
Commercially pure titanium sheet per AMS 4940 is used in aerospace heat shields, aircraft firewalls, galvanic isolation shims, chemical plant ducting, and marine structures where the combination of low density, high corrosion resistance, and weldability are the primary design requirements.
6Al-4V is recommended for use at temperatures from -350° to 750°F (-210° to 400°C). Applications outside this temperature range are possible in certain situations. The alloy is weldable. Complex shapes can be made via hot forming. It machines like an austenitic stainless steel.
Applications of AMS 4940 Commercially Pure Titanium
- Aircraft Turbine Engine Components
- Aircraft Structural Components
- Aerospace Fasteners
- Formula 1 Parts
- Medical Devices
- Marine Applications
- Ship Propellers
