What is Ti-6Al-4V (Grade 5) Titanium Alloy?
Ti-6Al-4V, also known as Grade 5 Титан, is the most widely used titanium alloy globally, often called the “workhorse” of the titanium industry. Its name comes from its chemical composition: 6% Aluminum and 4% Vanadium, with the balance being Titanium .
Ti-6Al-4V Titanium pipes are manufactured without a welded seam, providing superior strength and reliability for critical applications. They are typically produced to international standards such as ASTM B861 (general seamless pipes) and ASTM B338 (heat exchanger tubes)
Ti-6Al-4V Grade 5 titanium pipe provide an unmatched combination of lightweight durability and corrosion resistance. Whether for aerospace, medical, or industrial applications, they are the premium choice for engineers demanding the highest level of performance

The chemical composition of Grade 5 or 6al 4v titanium seamless pipes are as follows:
– Titanium: 88.6%
– Aluminum: 6.0%
– Vanadium: 4.0%
– Iron: 0.25%
– Oxygen: 0.20%
