AMS 6931 Titanium Alloy: Properties, Specifications & Uses

What Is AMS 6931 Titanium Alloy?

AMS 6931 is an aerospace specification for a high-performance titanium alloy. It defines the requirements the material must meet, including its chemical composition, mechanical properties, and quality.
Titanium is widely used in aerospace because it combines high strength with low weight. AMS 6931 is intended for applications where these properties are important and consistent material performance is required.

For engineers and buyers, AMS 6931 provides a clear material standard. It helps ensure that the titanium supplied meets the required strength, composition, dimensions, and quality controls.
The specification is mainly associated with aerospace and other demanding engineering applications where material reliability and traceability are important.

AMS 6931 Mechanical Properties

AMS 6931 titanium alloy is designed for applications that require high strength with relatively low weight. Its mechanical properties make it suitable for demanding aerospace and engineering applications.
Typical mechanical properties include:

Property	Value
Tensile Strength	130–134 ksi
Yield Strength	120–126 ksi
Elongation	6–10%

The tensile strength shows how much pulling force the material can withstand before it breaks. The yield strength indicates the stress at which permanent deformation begins. Elongation describes how much the material can stretch before fracture.

With its high tensile and yield strength, AMS 6931 can handle significant loads while keeping component weight relatively low. This combination is one reason titanium alloys are widely used in aerospace structures and other high-performance components.

AMS 6931 Physical and Performance Properties

In addition to its high mechanical strength, AMS 6931 titanium alloy offers the performance characteristics expected from aerospace titanium alloys. These properties make it useful where both weight and long-term reliability matter.

Key Properties of AMS 6931

· Low density: Titanium is much lighter than many high-strength steels, helping reduce component weight.
· High strength-to-weight ratio: AMS 6931 can provide high strength without adding unnecessary weight.
· Corrosion resistance: Titanium naturally forms a protective oxide layer, giving it good resistance to corrosion in many environments.
· Good fatigue performance: Its combination of strength and durability makes it suitable for components exposed to repeated loads.
· Heat resistance: It can maintain useful mechanical performance at elevated temperatures, depending on the application and service conditions.

These properties make AMS 6931 a good fit for weight-sensitive, high-strength components, particularly in aerospace and other demanding engineering applications.
