There are many grades of titanium and titanium alloys, including industrial pure titanium Grade 1, Grade 2, Grade 3, Grade 4, titanium alloy Grade 5, Grade 7, Grade 11, Grade 23, Grade 12, Ti 5Al-2.5Sn, etc. The performance of titanium alloys of different grades may vary greatly. How to choose the appropriate grade for industrial use of titanium alloys? What are the differences and applicable scenarios of these grades?
Ti 6Al-4V (Grade 5)
Referred to as the “workhorse” of titanium alloys, Ti 6Al-4V or Grade 5 titanium is the most commonly used of all titanium alloys. It accounts for 50% of the total titanium usage worldwide.
Its availability lies in its many benefits. Ti 6Al-4V can be heat treated to increase its strength. It can be used in welded structures at service temperatures up to 600°F. The alloy has high strength with light weight, useful formability, and high corrosion resistance. The availability of Ti 6AI-4V makes it an optimal alloy for use in multiple industries such as aerospace, medical, marine, and chemical processing industries. It can be used to create the following technical content: Aircraft turbines, engine components, aircraft structural components, aerospace fasteners, high-performance auto parts, marine applications, sports equipment
Grade 7
Mechanically and physically equivalent to Grade 2, except for the addition of the interstitial element palladium, making it an alloy. Grade 7 has excellent weldability and properties and is the most corrosion-resistant of all titanium alloys. It is the most corrosion-resistant in reducing acids. It can be used for chemical processes and production equipment parts, and it has extremely strong corrosion resistance, especially in reducing acid environments.
Grade 11
Grade 11 is very similar to Grade 1, except that a small amount of palladium is added to enhance the corrosion resistance, making it an alloy. This corrosion resistance can be used to prevent crevice corrosion and reduce acids in chloride environments.
Other useful properties include optimal ductility, cold formability, useful strength, impact toughness, and excellent weldability. This alloy can be used in the same titanium applications as Grade 1, especially where corrosion is a concern, such as Chemical Processing, Chlorate Manufacturing, Desalination, Marine Applications, etc.
Grade 12
Gr Grade 12 Titanium is given an “Excellent” grade because of its high-quality weldability. It is a highly durable alloy that offers great strength at high temperatures. Grade 12 Titanium has similar properties to 300 series stainless steels.
The alloy can be hot or cold formed using press forming, hydroforming, stretch forming, or drop hammering. Its ability to be formed in a variety of ways makes it useful in many applications. The high corrosion resistance of this alloy also makes it invaluable to those manufacturing equipment where crevice corrosion is a concern. It can be used in the following industries and applications: Shells and Heat Exchangers, Hydrometallurgical Applications, High-Temperature Chemical Manufacturing, Marine and Airline Components
Ti 6AL-4V ELI (Grade 23)
Ti 6AL-4V ELI is a higher purity form of Ti 6Al-4V. It can be made into coils, strands, wires, or flat wires. It is the first choice for any situation where high strength, lightweight, good corrosion resistance, and high toughness are required. It has excellent damage tolerance to other alloys. These advantages make Grade 23 the ultimate dental and medical titanium grade. Due to its biocompatibility, good fatigue strength, and low modulus, it can be used in biomedical applications such as implantable components. It can also be used in detailed surgical applications such as Orthopedic pins and screws, Orthopedic cables, Surgical implants, Orthodontic appliances, In joint replacements, Cryogenic containers, Bone fixation devices
Ti 5Al-2.5Sn
Ti 5Al-2.5Sn is a non-heat treatable alloy that allows for good weldability and stability. It also has high-temperature stability, high strength, good corrosion resistance, and good creep resistance. Creep refers to the phenomenon of plastic strain occurring at high temperatures for a long time. It is mainly used in aircraft and airframe applications and cryogenic applications.
