Titanium Alloy

Titanium is as strong as steel but much less density. It is therefore important as an alloying agent with many metals including aluminium, molybdenum and iron. These alloys are mainly used in aircraft, spacecraft and missiles because of their low density and ability to withstand extremes of temperature. They are also used in golf clubs, laptops, bicycles and crutches.

Power plant condensers use titanium pipes because of their resistance to corrosion. Because titanium has excellent resistance to corrosion in seawater, it is used in desalination plants and to protect the hulls of ships, submarines and other structures exposed to seawater.

Titanium metal connects well with bone, so it has found surgical applications such as in joint replacements (especially hip joints) and tooth implants.

The largest use of titanium is in the form of titanium(IV) oxide. It is extensively used as a pigment in house paint, artists’ paint, plastics, enamels and paper. It is a bright white pigment with excellent covering power. It is also a good reflector of infrared radiation and so is used in solar observatories where heat causes poor visibility.

Titanium (IV) oxide is used in sunscreens because it prevents UV light from reaching the skin. Nanoparticles of titanium (IV) oxide appear invisible when applied to the skin.


We offer a wide range of Titanium Alloys known for their excellent corrosion resistance, high strength-to-weight ratio, and outstanding durability across various applications. Our available grades include Grade 1 (commercially pure with excellent formability), Grade 2 (most widely used with balanced strength and corrosion resistance), Grade 5 (Ti-6Al-4V, the most commonly used titanium alloy with high strength), Grade 7 (similar to Grade 2 with added palladium for enhanced corrosion resistance), Grade 9 (Ti-3Al-2.5V, offering excellent weldability and strength), and Grade 12 (a titanium alloy with added molybdenum and nickel for superior corrosion resistance in reducing and oxidizing environments).

Titanium Grade 1

Titanium Grade 1 is the softest and most ductile of all commercially pure titanium grades. It offers exceptional corrosion resistance, especially in oxidizing environments and marine atmospheres. Due to its high ductility and formability, it is ideal for applications requiring complex forming and deep drawing. This grade is widely used in chemical processing, marine hardware, medical devices, and aerospace components where moderate strength and high corrosion resistance are needed. It is also non-magnetic and biocompatible, making it suitable for medical applications.

Titanium Grade 2

Titanium Grade 2 is the most widely used commercially pure titanium grade. It provides a great balance of strength, ductility, and weldability, along with excellent corrosion resistance in both oxidizing and mildly reducing environments. It is suitable for a wide range of industrial applications including heat exchangers, pressure vessels, desalination systems, and marine structures. Grade 2 titanium is also used in aerospace applications and medical equipment due to its non-toxic and non-magnetic properties. Compared to Grade 1, it has slightly higher mechanical strength.

Titanium Grade 5

Titanium Grade 5, also known as Ti-6Al-4V, is the most widely used titanium alloy, accounting for more than 50% of total titanium usage globally. It contains 6% aluminum and 4% vanadium, offering excellent strength-to-weight ratio, outstanding fatigue resistance, and high corrosion resistance. This grade is not as formable as commercially pure grades but offers superior mechanical properties. It is primarily used in aerospace structures, engine components, marine applications, surgical implants, and high-performance automotive parts. Grade 5 is heat treatable and suitable for high-stress environments.

Titanium Grade 7

Titanium Grade 7 is similar to Grade 2 in terms of mechanical properties but contains a small amount of palladium (0.12% to 0.25%), which significantly enhances its corrosion resistance in reducing and highly acidic environments, including chlorides and other aggressive chemicals. This makes Grade 7 ideal for chemical processing, desalination systems, and pollution control equipment. It has excellent weldability and formability, and is often chosen for critical service applications in industries such as petrochemical, chemical manufacturing, and power generation.

Titanium Grade 9 (Ti-3Al-2.5V)

Titanium Grade 9, or Ti-3Al-2.5V, is an alloy that bridges the gap between commercially pure titanium and high-strength Grade 5. It offers excellent corrosion resistance, good strength, and outstanding cold-formability. Due to its superior weldability and moderate strength, it is widely used in aerospace hydraulic tubing, aircraft structures, sporting goods, and marine applications. Grade 9 is also a preferred material in bicycle frames and high-performance exhaust systems. It retains its strength even at moderately elevated temperatures, making it versatile and reliable.

Titanium Grade 12

Titanium Grade 12 contains small additions of molybdenum (0.2-0.4%) and nickel (0.6-0.9%), which give it excellent corrosion resistance in highly acidic or oxidizing environments, including hot brines, wet chlorine gas, and nitric acid. It combines good strength with superior weldability and fabricability, making it an ideal material for industrial heat exchangers, pressure vessels, and chemical processing plants. Grade 12 is also used in marine and offshore applications, especially where both strength and corrosion resistance are critical. Its performance in high-temperature environments also makes it valuable in energy production systems.
