Titanium alloy, among many cutting-edge materials of the new age, plays a pivotal role in the remarkable technological advancements of any nation, particularly in industries including defense. MIDHANI (Mishra Dhatu Nigam Limited) of India has achieved a significant milestone by successfully synthesizing a special Titanium alloy named ‘Titan6242S’, which will drive India’s AMCA Program.

When pure titanium, as the primary material, is integrated with different metallic and chemical substances in desired proportions and subsequently undergoes a cooling procedure, it yields a titanium alloy exhibiting high strength, low density, and high-quality corrosion resistance.

Titanium alloy is classified into many types as follows:

The American Society of Mechanical Engineers (ASME) classifies titanium alloys into various commercial grades such as Grade-1, Grade-2, Grade-3, and Grade-4, each offering different tensile and yield strengths.

What is MIDHANI’s Titan6242S Titanium Alloy? Why it is Significant for AMCA Program?

Titan6242S is a 3D printed titanium alloy wherein titanium is infused with nearly 6.5% aluminum, 4.5% zirconium, 2.2% molybdenum, and other proportions of tin, silicon, and other residual materials. It is a type of alpha titanium alloy that provides high-grade mechanical strength, stability, and creep resistance up to 550-565 degrees Celsius.

This alloy is specifically designed to construct the casing of the high-pressure compressor for the AMCA fighter jet engine, engineered to endure severe stress and high temperatures during operation.

MIDHANI overcame challenges through thorough research on the hot working behavior of the Titan6242S titanium alloy and refinement of the melting process. These challenges are critical to manufacturing AMCA parts in the designed and desired shapes.

India is now one step closer to completing the list of indigenous content for the AMCA program. India’s self-reliance in manufacturing this titanium alloy domestically marks a milestone and helps reduce dependence on foreign suppliers in this regard. National security and growth in domestic technology are the two key takeaways from this important success.

In other sectors, the Titan6242 titanium alloy is also heavily used in manufacturing engine casings for race cars and spacecraft parts, which operate in high-temperature environments. India’s MIDHANI might find a place among potential suppliers of T6242 titanium alloys to these industries involving such titanium alloy.
