Understanding the Strength Characteristics of Different Grade Titanium Screws
May 22, 2023
Our company can supply titanium screws of various strengths and grades. The strength of titanium screws varies depending on the grade of titanium.
The strength of titanium screws depends on the grade and characteristics of the titanium alloy used. Here are typical strength ranges for common titanium screw materials:
Commercially Pure Titanium:
Grade 1: Strength is approximately 240 MPa.
Grade 2: Strength is approximately 345 MPa.
Grade 4: Strength is approximately 550 MPa.
Titanium Alloys:
Ti-6Al-4V (Grade 5): Strength ranges from approximately 895 MPa to 1000 MPa, depending on the specific heat treatment.
Ti-5Al-2.5Sn (Grade 6): Strength is approximately 950 MPa.
Ti-0.2Pd (Grade 7): Strength ranges from approximately 345 MPa to 483 MPa.
Ti-3Al-2.5V (Grade 9): Strength is approximately 860 MPa.
Ti-0.3Mo-0.8Ni (Grade 12): Strength ranges from approximately 483 MPa to 586 MPa.
Ti-6Al-4V ELI (Grade 23): Strength ranges from approximately 860 MPa to 1035 MPa, depending on the specific heat treatment.
Ti-6Al-6V-2Sn (Grade 26): Strength ranges from approximately 950 MPa to 1100 MPa, depending on the specific heat treatment.
Ti-6Al-7Nb (Grade 27): Strength ranges from approximately 860 MPa to 1035 MPa, depending on the specific heat treatment.
Ti-13Nb-13Zr (Grade 29): Strength ranges from approximately 420 MPa to 550 MPa.
Grade 1 is the most ductile and softest grade of commercially pure titanium, offering lower strength but excellent formability and corrosion resistance. Grade 7 is an alloyed titanium grade known for its excellent corrosion resistance, especially in reducing and mildly oxidizing environments, with slightly higher strength compared to Grade 1.
Grade 2 titanium alloy is a commercially pure titanium grade known for its excellent corrosion resistance, formability, and weldability. It offers good strength while maintaining a high level of ductility. Grade 2 titanium is commonly used in various industries, including chemical processing, marine applications, and medical implants.
Grade 5 titanium alloy, also known as Ti-6Al-4V, is a popular titanium alloy known for its high strength-to-weight ratio, excellent corrosion resistance, and heat resistance. It is widely used in aerospace, automotive, and other high-performance applications where lightweight yet strong materials are required.
Grade 7 titanium alloy, also known as Ti-0.2Pd, is an alloyed titanium grade that contains a small amount of palladium. It offers excellent corrosion resistance, particularly in reducing and mildly oxidizing environments. Grade 7 is commonly used in applications where superior corrosion resistance is required, such as in chemical processing, marine environments, and medical implants.
Grade 12 titanium alloy, also known as Ti-0.3Mo-0.8Ni, is an alloyed titanium grade that contains molybdenum and nickel. It offers a good balance of strength, formability, and corrosion resistance. Grade 12 is commonly used in applications where high corrosion resistance and moderate strength are required, such as in chemical processing and marine environments.
Grade 23 titanium alloy, also known as Ti-6Al-4V ELI, is an alloyed titanium grade that is often used in medical and surgical applications. It offers high strength, excellent biocompatibility, and good corrosion resistance. Grade 23 is specifically designed to provide enhanced fracture toughness and fatigue resistance compared to other titanium alloys.
These are just a few examples of titanium alloy grades commonly used for titanium screws. It's important to note that the strength can vary based on the specific composition, heat treatment, and manufacturing processes.
Again, it's important to note that these strength values are approximate ranges and can vary depending on specific manufacturing processes, heat treatments, and product specifications. For precise strength information related to specific titanium screw grades, our company will supply you with MTC showing all the composition and properties of titanium screws and titanium materials.
