Characteristics Of Commercial Titanium

Titanium is commercially available today in different grades and alloys. Each titanium grade and alloy possesses properties that make it beneficial to particular industrial applications and processes.

Here are some of the most common pure titanium grades available commercially.

Grade 1 titanium

This titanium grade is the most ductile among all the pure titanium grades. It is also the softest and has the best formability. It has excellent high impact durability and toughness and great corrosion resistance.

Because it is easy to form, it is commonly used in the production of titanium tubes and plates for the following applications:

  • Automotive parts
  • Architecture
  • Aerospace structures
  • Chemical processing
  • Desalination
  • Dimensional stable anodes
  • Marine frames and parts
  • Medical apparatus and implements

Dubbed as the “workhorse” of all commercially pure titanium grades, grade 2 titanium has a wide range of usability. It is relatively easy to obtain and a bit stronger than grade 1 titanium. It also has great resistance to corrosion.

Because of its excellent strength, weldability, formability, and ductility, grade 2 titanium is frequently used in making titanium sheets and bars for:

  • Airframe skins
  • Architecture
  • Chemical processing
  • Desalination
  • Exhaust pipe shrouds
  • Hydro-carbon processing
  • Marine applications
  • Medical instruments and tools
  • Power generation 

Grade 3 titanium 

This is the least popular and used among the commercially available pure titanium grades. Despite that, its value and attributes are nothing to ignore. It is stronger than the two other grades, has comparable ductility, possesses greater mechanicals, and a little bit less formability.

It is frequently used in applications that require high corrosion resistance and strength, such as:

  • Aerospace and airframe structures
  • Chemical processing
  • Marine parts and components
  • Medical and surgical implements 

Grade 4 titanium 

Being the strongest of all four commercially pure titanium grades, grade 4 titanium is known for its great weldability, formability, and resistance to corrosion. It is often utilized in the following applications:

  • Airframe and aerospace components
  • Condensor tubing
  • Heat exchangers
  • Cryogenic vessels
  • Surgical tools and hardware
  • Pickling baskets
  • CPI equipment
