Raw Materials
The layer where wars are actually won — and where India is weakest
Every airframe, engine disc, armour plate and rocket motor traces back to a handful of strategic materials. India controls almost none of them at scale. This layer decides how fast every downstream ramp can actually go — HAL can double Tejas assembly lines, but if titanium forgings queue at VSMPO-alternatives, aircraft wait. The state has finally noticed: critical-mineral missions, KABIL's lithium/cobalt acquisitions abroad, and rare-earth magnet PLI proposals all target this layer.
Material-by-material breakdown
Titanium sponge & mill products
85%Aerospace-grade sponge from Japan/Kazakhstan/Russia; mill products (bar, plate, forging stock) largely imported. Ti-6Al-4V is 80%+ of aerospace demand.
India play: KMML sponge 10x expansion; Midhani melt; PTC Aerolloy castings; Bharat Forge Ti forging cell
Rare earths & magnets
90%NdFeB and SmCo magnets for seekers, actuators, sonars, EW tubes. China dominates refining + magnet making; Japan (Shin-Etsu, TDK) is the non-Chinese alternative.
India play: IREL concentrate → planned magnet PLI; Midhani-IREL SmCo pilot; startup Mag-sourcing via Mahindra/Attero recycling
Superalloys (Ni-base)
70%Inconel 718/625, CM247, single-crystal alloys for engine hot sections. Melt capacity exists (Midhani); master-alloy and Re/Hf inputs imported.
India play: Midhani VIM/VAR expansion; PTC vacuum investment casting; GTRE Kaveri-derivative revival
Aerospace carbon fibre & prepreg
95%T-700/T-800 class fibre and film-adhesive prepregs are export-licensed items; LCA wings and AMCA structures need tonnes per aircraft.
India play: NAL-HAL autoclave ecosystem; private composites (Kineco, TataAdvanced) on imported fibre; DRDO ACECOST fibre line pilot
Armour & naval steels
25%DMR-249A/B (hull), Jackal-class armour plate largely indigenised via SAIL/Midhani; ultra-high-hardness add-on armour still imported.
India play: SAIL Alloy Steels Durgapur; Midhani BHABHA-grade plates; Krishna Defence fabrication
Energetics & propellant chemicals
25%RDX/HMX and composite propellant production established (ordnance factories, Solar, Premier); nitrocellulose and some oxidisers still imported from Europe.
India play: Solar Industries HMX + Pinaka energetics scale-up; Premier solid boosters; Munitions India NC expansion
Market structure & pricing dynamics
- ▸Titanium sponge: ~60% of global aerospace-grade supply historically tied to Russia (VSMPO-AVISMA), Japan (Toho, OSAKA Ti) and Kazakhstan (UKTMP). Post-2022 sanctions re-routing pushed Western aerospace to Japan/Kazakh material at 20-40% premiums.
- ▸Rare earths: China refines ~90% of magnet-grade NdPr. Every Indian missile seeker, sonar transducer and EW travelling-wave tube sits on this dependence. 2025 Chinese export controls on heavy REs (Dy, Tb) hit global defence primes directly.
- ▸Superalloy feedstock (Ni, Co, Re): rhenium — essential for single-crystal blades — is a ~50-tonne/year global market; Chile + US control most. No Indian source.
- ▸Carbon fibre: aerospace-grade (T-800 class) is export-controlled by Japan (Toray) and the US (Hexcel). India's IACS-grade domestic production (Kemrock legacy, NAL pilot lines) is orders of magnitude short.
- ▸Energetic chemicals: nitrocellulose and specialty oxidiser supply chains strained globally since Ukraine — European propellant makers (Eurenco, Nitrochemie) are booked out years.
India's position — programs and gaps
- ▸KMML (Kerala Minerals) runs India's only titanium sponge plant (~500 tpa aerospace-grade vs ~5,000+ tpa need at full aircraft ramp) — a 10x scale-up is sanctioned but execution is slow.
- ▸IREL mines monazite beach sands but ships most RE concentrate for toll refining; magnet-grade NdPr production is just beginning at BARC-adjacent pilot scale.
- ▸Midhani is the sole superalloy melt shop (vacuum induction + VAR); capacity ~6,000 tpa across superalloys/Ti/special steels — adequate for missiles, thin for aeroengines at scale.
- ▸DMR-249A naval steel (SAIL + DRDO) is the one genuine victory: INS Vikrant used ~26,000 t of fully indigenous warship steel, breaking Russian ABA-grade dependence.
- ▸National Critical Mineral Mission (2025, ₹16,300 Cr) + KABIL's Argentina lithium blocks are the state's answer — a decade-long build at best.
What an expert watches
- ▸KMML sponge expansion award dates and whether HAL/PTC sign offtake MoUs — the tell for a real Ti value chain.
- ▸IREL → magnet-maker JV announcements (talks with Japanese and Korean magnet firms recur every year).
- ▸Rhenium / hafnium sourcing disclosures in Midhani annual reports — precursor to any serious single-crystal blade program.
- ▸Chinese RE export-license behaviour after each border incident — the single biggest exogenous risk to Indian missile electronics schedules.
