Titanium and its alloys are lightweight, strong metals used in aerospace applications, offering excellent corrosion resistance and high heat transfer efficiency. Various grades exist, each with specific compositions and properties, suitable for different industrial and engineering applications. Key grades include commercially pure grades for general corrosion and high-strength alloys for critical structural components in aircraft.

1. Introduction of Titanium and titanium alloys
They are used in airplanes, missiles and rockets where strength,
low weight and resistance to high temperatures are important.
This alloy is immune to corrosive attack by salt seawater or
marine atmospheres. Often used in propeller shafts, rigging and
other parts of boats that are exposed to seawater. It also exhibits
exceptional resistance to wide range of acids, alkalis natural
waters and industrial chemicals. Titanium is a strong,
lightweight metal. It is also strong as steel but 45% lighter. It is
also twice as strong as aluminium. The heat transfer properties
of titanium approximate those of admiralty brass and copper
nickel.
 Excellent Corrosion Resistance
 Superior Strength
 High Heat Transfer Efficiency
Grade 1 - 4
Commercially pure, for general industrial corrosion applications. They
unalloyed and considered commercially pure or "CP". Generally the
tensile and yield strength goes up with grade number for these "pure"

2. grades. The difference in their physical properties is primarily due to the
quantity of interstitial elements. They are used for corrosion resistance
applications where cost and ease of fabrication and welding are
important.
Grade 5
contains 6.0% Aluminium 4% Vandadium. High strength titanium alloy,
used in critical aircraft structural components.
Grade 6
Contains Al 4.0-6.0,Sn 2.0-3.0. Airframes and jet engines, due to its
good weldability, stability and strength at high temperatures.
Grade 7
contains 0.12 to 0e.25% Palladium. This grade is similar to Grade 2. The
small quantity of Palladium added gives it enhanced crevice corrosion
resistance at low temperatures and high PH.

3. Grade 9
contains 3.0% Aluminium and 2.55 Vandadium. This grade is a
compromise between the ease of welding and manufacturing of the
"pure" grades and the high strength of Grade 5. It is commonly used in
aircraft tubing for hydraulics and in athletic equipment.Improved strength
titanium alloy for industrial corrosionapplications
Grade 11
contains 0e.12 to 0.25% Palladium. This grade has enhanced corrosion
resistance.CP Grade 1 with added Palladium for industrial corrosion
applications.
Grade 12
contains 0.3% Molybdenum and 0.8% Nickel. Added moly and nickel for
industrial corrosionapplications.
Grade 16

4. contains 0.04 to 0.08% Palladium. CP Grade 2 with added Palladium for
industrial corrosionapplications.
Grade 17
contains 0.04 to 0.08% Palladium. Similar to Grade 11 with extra
Palladium for industrial corrosionapplications.
Grade 18
Contains Al 3.0%, V 2.5%, Pd 0.05%. Similar to Grade 9 with added
Palladium for industrial corrosion applications where additional strength
is required
