The main difference between titanium grade 2 and titanium grade 5 lies in their composition and the associated mechanical properties. Titanium Grade 2, also known as pure titanium, consists mainly of pure titanium with very small amounts of iron and oxygen. It is a softer, more ductile material that nevertheless has good corrosion resistance, especially in less aggressive environments. Due to its good workability, it is often used in the aerospace, medical and chemical industries.
Titanium Grade 5, also known as Ti-6Al-4V, is an alloy containing 90% titanium, 6% aluminum and 4% vanadium. These alloying elements give the material greater strength and rigidity compared to Grade 2, but also make it less ductile and more difficult to work with. Grade 5 offers an excellent combination of high strength and good corrosion resistance and is therefore preferred for use in the aerospace industry, high performance machinery and medical implants.
To summarize, Titanium Grade 2 is a pure titanium with good corrosion resistance properties and flexible mechanical properties, while Titanium Grade 5 is a titanium alloy with higher strength and stiffness, but with lower ductility and more complex processing.
