Titanium Product Guide

Much like other metals in the materials industry, Titanium has many different grades. Grade 2 being the most commonly used in pure titanium and Grade 5 (6AL-4V) is the most commonly used for alloy titanium, both being considered the “Workhorse” in the titanium world. Titanium is widely used because it’s high corrosion resistance and high strength to weight ratio. Typical applications are; aerospace, automotive, medical, industrial, chemical, petroleum and other common industries.

Grade 1

Grade 1 titanium is a relatively low strength with high ductility. It is the softest and most ductile of the various grades of titanium.  Because of these qualities, Grade 1 is commonly used for it’s formability.

Common Applications:

  • Chemical Processing
  • Architecture
  • Medical
  • Marine
  • Automovtive
  • Air Craft

Grade 2

Grade 2 Titanium has the best combination of strength, ductility and weld-ability. Commonly known as the “workhorse” in the titanium industry, Grade 2 is more useable and available.  

Common Applications:

  • Architecture
  • Medical
  • Marine
  • Exhaust
  • Air Craft
  • Chemical
  • Automotive

Grade 3

Grade 3 titanium is one of the least used grades of commercially pure titanium. Grade 3 is stronger than both grade 1 and 2, but similar in ductility and less formability. Grade 3 has a higher mechanical properties allowing for greater use in applications needing moderate strength and higher corrosion resistance.

Common Applications:

  • Aerospace
  • Chemical
  • Medical
  • Marine

Grade 4

Grade 4 Titanium is well known for its high strength, corrosion resistance and good formability. Grade 4 is also most widely used in the medical industry.

Common Applications:

  • Medical
  • Cryogenic
  • Surgical Equipment
  • Heat Exchange

Grade 5 (6AL-4V)

Grade 5, also known as 6AL-4V, is considered the “workhorse” for the alloy titanium. Most commonly used because of its high strength to weight ratio and its corrosion resistance. Grade 5 can also be heat treated to increase the strength.

Common Applications:

  • Aerospace
  • Automotive
  • High-performance
  • Marine
  • Sports equipment
