Titanium Grade 5 / 6Al4V
Titanium Grade 5 has good tensile properties at ambient temperature and a useful creep resistance up to 300oC (570oF). Resistance to fatigue and crack propagation is excellent. Like most titanium alloys, Grade 5 has outstanding resistance to corrosion in most natural and many industrial process environments.
Chemical Composition Titanium Grade 5 / 6Al4V
Applications of Titanium Grade 5 / 6Al4V Titanium Grade 5 is a pure alpha-beta titanium with aluminium as the alpha stabilizer and vanadium as the beta stabilizer. This alloy is primarily used for corrosion resistance and is the most widely used specification in all product forms. The alloy features very high strength, good corrosion resistance, excellent strength-to-weight ratio and high strength at cryogenic temperatures. Physical Properties
Titanium Grade 5 / 6Al4V Corrosion Resistance Ti 6Al 4V instantaneously produces a ceramic oxide layer on its surface, which protects it from carrion in all but the most severe of environments. Because of this, grade 5 Titanium is widely used in saltwater applications, as well as humid environments. It is also moderately resistant to highly acid environments though titanium alloys containing palladium are better. Heat Treatment Ti 6Al 4V alloy is widely heat-treated to further improve its properties. It is typically mill-annealed, solution-treated treated or aged. Stress relieving is used on formed and welded parts whilst beta annealing is used to improve the alloy’s strength. Hot Working Ti 6Al 4V is usually hot-worked in order to produce the desired microstructure through the process of recrystallisation. This keeps the alloys yield strength and hardness low and its ductility high. In grade 5 this is done at approximately 870°C to 980° C which stops the growth of excessive alpha phase. Cold Working Ti 6AL 4V is not easily cold-worked due to its low elastic modulus meaning it has a tendency to resume its prior shape. Grade 5 can be cold drawn and extruded though this is typically confined to smaller industrial processing facilities on commercially pure grades of titanium. Titanium Grade 5 / 6Al4V Machining Ti6Al4V parts have good machinability and can be machined as stock parts. The following factors contribute to efficient machining of Ti6Al4V parts: Low cutting speeds, high feed rate, generous quantities of cutting fluid, sharp tools and a rigid setup. You can learn more on our machining page.
Weldability Ti 6Al-4V can be welded using Ti 6Al-4V as a filler metal. The metal has to be shielded with inert gases to prevent the pickup of oxygen in the weld area which can cause embrittlement and failure. Gas tungsten arc welding is the most commonly used welding process for Ti 6Al-4V alloy, though gas metal arc welding is used for welding thicker sections. Ti 6Al-4V can be successfully welded using plasma arc welding, spot welding, electron beam, laser beam, resistance welding and diffusion welding. Conclusion ASTM grade 5 titanium is the most ubiquitous and versatile of titanium alloys. It is comprised of 90% titanium, 6% aluminium and 4% vanadium. It is an alpha-beta titanium alloy with aluminium stabilising the alpha phase and vanadium stabilising the beta phase. Ti 6 Al 4V is widely used because of its optimum blend of properties. It can undergo further processing to become better suited to specific applications.

Titanium Grade 2
When it comes to the world of titanium alloys, two of the most popular grades are Grade 2 and Grade 5. These two alloys are often compared regarding their strength, durability, and corrosion resistance. In this blog post, we will explore the differences between Grade 2 titanium and Grade 5 titanium to help you decide which alloy is the best for your specific use case. Chemical Composition Titanium Grade 2
ASTM Product Specifications
Applications of Titanium Grade 2
Physical Properties
Titanium Grade 2 Corrosion Resistance It is also important to note that Grade 2 titanium has a higher corrosion resistance than Grade 5 titanium in certain environments. Grade 2 titanium is highly corrosion-resistant in most natural and industrial environments, while Grade 5 titanium may experience galvanic corrosion in certain conditions. Heat Treatment Titanium grade 7 is annealed at 650 – 760°C, still air-cooled. Pickling to remove the alpha case may be needed before further fabrication or machining. Stress relief at 480 – 595°C, air-cooled, may be required to improve dimensional stability for critical components. Cold Working The cold work characteristics of this material is similar to that of a moderately tempered austenitic stainless steel. In multiple cold-forming operations, intermediate stress relief is recommended to prevent tearing or other material damage. Post-work annealing is required to reattain optimum performance characteristics Properties and Applications While Grade 2 and Grade 5 titanium alloys have unique properties and applications, the biggest difference is their strength. Grade 5 titanium is significantly stronger than Grade 2 titanium and has a higher tensile strength. This means that Grade 5 is better suited for applications that require high strength and durability, such as aerospace engineering. Strength In addition to strength, another important factor to consider when choosing between these two titanium alloys is their cost. Grade 5 titanium is typically more expensive than Grade 2 titanium due to its more complex manufacturing process. However, the added cost of Grade 5 titanium is often justified in high-performance applications where strength and durability are paramount. Titanium Grade 2 Machining Titanium grade 2 is readily machinable by conventional methods. It is similar to austenitic stainless steels for machinability. Like stainless steel, titanium has a low thermal conductivity and heat dissipation is poor, so generous use of coolant is recommended. Sharp tools are essential. Cuts should be deep and continuous, with low cutting speeds.
Weldability Titanium grade 2 is readily weldable by GMAW and GTAW processes. Preheat or post-weld heat treatment are not needed. The area immediately surrounding the welds must be CLEAN, free from all grease and shop dirt, including pencil marks. Abrasive cleaning can be used, or solvent cleaning or pickling with a mixture of nitric and hydrofluoric acids. A trailing gas shield must be applied to all areas above 450°C in addition to the normal welding torch gas shield, to prevent heavy oxidation during cooling. Matching filler metal to AWS ERTi-2 is used. The gas shield must be low in hydrogen, oxygen and nitrogen, all of which readily dissolve in titanium and cause embrittlement. Conclusion In conclusion, both Grade 2 titanium and Grade 5 titanium are excellent options for various industrial applications. While Grade 2 is the most commercially pure titanium alloy known for its high corrosion resistance, Grade 5 is significantly stronger and better suited for high-performance applications. When deciding between these two alloys, consider your specific use case and weigh the cost versus the added benefits of each. Working with a reputable titanium supplier is always important to ensure you use the right alloy for your application.
