Products Description
Titanium Grade 9, also known as Ti-3Al-2.5V, is a titanium alloy that offers a balanced combination of strength, formability, and corrosion resistance.
Composition
The chemical composition of Titanium Grade 9 is as follows:
Titanium (Ti): Approximately 90%
Aluminum (Al): 3%
Vanadium (V): 2.5%
Titanium Grade 9 is a versatile alloy, ideal for applications where a balance between strength, weight, and formability is required. It is particularly favored in industries like aerospace, sports equipment, and marine applications.
Strength:
Titanium Grade 9 is significantly stronger than commercially pure titanium grades like Grade 2 but not as strong as Grade 5 (Ti-6Al-4V).
It has a tensile strength of around 620 MPa (90 ksi), providing a good balance between strength and weight.
Corrosion Resistance:
Similar to other titanium alloys, Grade 9 exhibits excellent corrosion resistance, particularly in oxidizing and mildly reducing environments.
It is resistant to corrosion in seawater and a variety of industrial environments, making it suitable for marine and chemical applications.
Formability:
One of the key advantages of Titanium Grade 9 is its superior formability compared to stronger alloys like Grade 5.
It can be cold-worked more easily, making it ideal for applications requiring complex shapes or for use in manufacturing processes like tube forming.
Weldability:
Grade 9 offers good weldability, though care must be taken to avoid contamination during the welding process, which is typical for titanium alloys.
Applications:
Aerospace: Used in hydraulic tubing, fuel lines, and other components where a combination of moderate strength and weight savings is needed.
Sports Equipment: Commonly used in high-end bicycle frames and golf clubs due to its excellent strength-to-weight ratio and formability.
Marine: Suitable for marine hardware and components exposed to seawater.
Medical Devices: Sometimes used in medical applications, though more often titanium alloys with higher biocompatibility are preferred.
Physical Properties:
Density: ~4.48 g/cm³, providing a good strength-to-weight ratio.
Melting Point: ~1649°C (3000°F), similar to other titanium alloys, offering stability in high-temperature applications.
Thermal Conductivity: Lower than that of steel and aluminum, which may be advantageous or a limitation depending on the application.
