Titanium 6AL-4V (Grade 5) is the most widely used titanium grade. This grade is well suited for most applications and is the titanium grade used for most industrially produced components. Grade 5 titanium is stronger than commercially pure titanium but less robust than titanium alloys.
What is the difference between grades of titanium?
Grades 1, 2, and 3 are commercially pure titanium. Grades 4, 5, 6, 7, 8 and 9 are alloys containing varying amounts of other metals. Grades 7 and 9 are most commonly used in biomedical applications. Grades 1, 2 and 3 are used in aerospace and industrial areas.
Let’s talk about Grade 1, 2, 5.
Grade 1 titanium is pure titanium, and it has the highest elasticity. Grade 2 titanium is a titanium alloy that is strengthened with aluminum and vanadium, and Grade 2 titanium is stronger than Grade 1 titanium but less ductile than Grade 1 titanium.
Grade 5 titanium is commonly used for medical devices due to its biocompatibility. Stronger than Grade 2 titanium and about 1/3 of Grade 1 titanium in strength.
Is grade 2 or grade 5 titanium better?
Grade 2 Titanium has a wider selection of diameters and wall thicknesses, making it a good choice for various projects. It is also a lower-cost alternative to Grade 5 Titanium.
Grade 5 Titanium is stronger, lighter, and more durable than Grade 2 Titanium. Although it has the same corrosion resistance as Grade 2, Grade 5 Titanium is 40% stronger.
While both alloys are excellent, Grade 5 Titanium isn’t always the best titanium choice for cost-effective, precision production. Grade 2 Titanium is 2/3 the cost of Grade 5 and is very similar and superior to Grade 5 Titanium in some applications.
