Aerospace-grade superalloy & titanium manufacturing

For most of its history as an aircraft-building nation, India could not make the metal its aircraft were made of. Titanium alloys, nickel-based superalloys, the specialty steels inside every engine — historically, these arrived almost entirely as imports, and that single dependence constrained every attempt at an indigenous aero-engine or airframe.

The difficulty is real. Only five or six nations on Earth produce aerospace-grade titanium at scale: the United States, Russia, China, France, the United Kingdom, and — since January 2025 — India. The reason the club is so small is that the work demands an integrated chain of hard capabilities: vacuum melting and remelting to purify the metal, large-tonnage forging to shape it, single-crystal investment casting for the hottest turbine parts, and defect-detection so complete that every gram carries a traceable history. A weakness anywhere breaks the whole.

India now holds working versions of each link. Mishra Dhatu Nigam (MIDHANI), operating from Hyderabad since 1982 and the country's only titanium-alloy manufacturer, delivered CEMILAC-certified superalloy cast sticks to Hindustan Aeronautics in March 2026 for aero-engine use, and won a ₹6,000 crore HAL superalloy order in 2025. PTC Industries' subsidiary Aerolloy Technologies commissioned India's first aerospace-grade titanium VAR furnace in Lucknow, then inaugurated a 6,000-tonne-per-year titanium and superalloy plant there in October 2025 on a ₹1,000 crore investment, and commissioned a 4,500/5,100-tonne open-die forging system in April 2026. Underneath sits the Defence Metallurgical Research Laboratory (DMRL), which developed an indigenous titanium-sponge process, the TITAN 26A and 29A high-temperature alloys, and single-crystal turbine-blade casting technology in 2021. PTC already exports titanium parts to BAE Systems, Safran, Dassault Aviation, and Israeli Aerospace Industries, and holds acceptances from CEMILAC for an AMCA titanium casting and Kaveri Derivative Engine turbine-blade work.

So why does the gap persist? Because demonstrated is not the same as proven at scale. MIDHANI's capacity constraints limit volume; PTC's facilities are in early commercial production; the hardest components — single-crystal blades for a full-production engine — are still being qualified rather than mass-produced. India has shown it can make the metal, not yet that it can supply an engine programme's full appetite reliably and cost-competitively against established global producers.

Closing that distance is a matter of running these new lines at volume, accumulating certified flight history, and holding price against exporters with decades of amortised infrastructure. The chain now exists. The next climb is turning it from capability into dependable, competitive supply.
