Titanium grade 5

The most popular of all titanium alloys

Ti6Al4V (3.7164 / 3.7165) is the most widely used titanium alloy globally, accounting for over 50% of the world’s titanium usage. This is largely due to its significant use in the aerospace industry, which fully leverages the benefits of this grade. Why is Titanium Grade 5 (Ti6Al4V / 3.7164 / 3.7165) so favored? The key lies in its excellent balance between weight, strength, corrosion resistance, and workability.

The properties of Titanium Grade 5 (Ti6Al4V / 3.7164 / 3.7165)

• Highly resistant to saltwater
• Highly resistant to high temperatures up to 430°C/806°F
• A good resistance to metal fatigue
• Low thermal expansion
• High strength-weight ratio
• Low elastic modulus, meaning a high stiffness

Strong alloy with a high UTS

Titanium grade 5 is very popular because of its high Ultimate Tensile Strength (UTS). It is more than 4 times as strong as Grade 1 titanium while retaining the same stiffness and thermal properties as the commercially pure titanium grades. The standard minimal UTS of Ti6Al4V is 895MPa. The Solution Treatment and Aging (STA) heat treatment significantly increase the mechanical values. It can result in a UTS of more than 1200MPa.

Several application areas of Titanium grade 5

The unique properties of Titanium Grade 5 (Ti6Al4V / 3.7164 / 3.7165) make it suitable for a wide range of applications:

• Aerospace: Ti6Al4V (3.7164 / 3.7165) is widely used for aircraft components due to its high strength and low weight.
• Heat Exchangers: Its high corrosion resistance and strength make it ideal for heat exchangers in industrial processes.
• Semiconductor Industry: Supports the manufacturing of components in the semiconductor industry due to its durability and precision.
• Subsea Applications: Ideal for underwater applications, such as submarine parts, because of its corrosion resistance and high strength.
• Satellite Components: Used in space technology for satellites due to its excellent performance under extreme conditions.
