Gas Turbine Equipment & Materials

CMC hot-section parts allow operation several hundred degrees above nickel superalloy limits with a third of the density and a fraction of the cooling air. GE's position derives from roughly three decades of continuous investment culminating in the LEAP and GE9X programmes, and from owning the full stack: it buys silicon carbide fiber, preforms it, infiltrates it with molten silicon, machines it and applies its own EBC. The barrier is process yield. Chemical vapour infiltration and melt infiltration are slow, high-scrap operations where yield is a function of accumulated furnace-run data that cannot be bought. This is a capability that has not been successfully replicated by a new entrant despite continuous OEM interest in alternatives.

High, but with a critical dependency that must be named precisely: GE does not control the fiber. Silicon carbide fiber is roughly 65% Japanese (Nippon Carbon approximately 45%, UBE 20%), with SGL Carbon at 10% the main European source. GE's 55% CMC share rests on a materials input controlled by two companies in one country. That is a bottleneck sitting behind a bottleneck, and it is why the silicon carbide fiber segment scores 59 on investability despite the modest reported margins of its participants.

Substitution is the primary threat specific to this segment's competitive position: additively manufactured refractory-alloy parts and improved single-crystal alloys with better coatings are competing solutions for the same temperature problem, and CMC has repeatedly slipped its adoption timeline. The second is that GE is not an investable expression of this bottleneck, trading at 42.26× with a Valuation score of 15.6, meaning the CMC franchise is already priced into a $373.6B market capitalisation where CMC is a small revenue fraction. The third is the fiber dependency itself: Japan's July 2019 export licensing restrictions on hydrogen fluoride and photoresist to South Korea demonstrated that a country holding a decisive share of an obscure specialty material will use it, and Japanese silicon carbide fiber fits that profile exactly, creating a supply risk that GE cannot hedge through its own manufacturing position.

Coating equipment here means atmospheric plasma spray, electron-beam physical vapour deposition and suspension plasma spray systems that deposit ceramic layers onto blade surfaces at controlled porosity and columnar microstructure. The moat is not the hardware. It is that each coating recipe — powder feedstock chemistry, plasma gun geometry, standoff distance, robot path, substrate preheat — is jointly qualified with the OEM against a specific engine part number, and Oerlikon's installed base carries thousands of such qualified parameter sets accumulated over decades. A competitor can build an equivalent plasma gun. It cannot hand a customer a validated process window for a GE 9HA first-stage blade without repeating a multi-year qualification campaign that the OEM has no incentive to fund. Oerlikon also operates 20% of the TBC application market, making it the only company in the chain that both sells the equipment and runs the job shops.

High on a five-year view. The EBC transition actually strengthens the position, because ytterbium disilicate and rare-earth silicate EBCs on silicon carbide CMC substrates require tighter deposition control than legacy zirconia TBCs on nickel, and the qualification burden rises with the specification. Replication would require a competitor to fund parallel qualification across multiple OEM programmes with no revenue during the campaign, a five-to-eight year, several-hundred-million-dollar commitment against a segment that generates perhaps low-single-digit billions of equipment revenue globally.

Three distinct threats. First, OEM vertical integration: GE, Safran and Rolls-Royce all operate in-house EBC application and could internalise equipment development, as Rolls-Royce has periodically done with process technology. Second, Oerlikon's financial distress: a -29.7% revenue decline, negative P/E of -45.98, Quality of 24.0, and a 17.91% distribution yield reflecting portfolio restructuring rather than sustainable payout. A monopolist in financial distress can be acquired or forced to divest the crown jewel on terms set by the buyer. Third, precedent risk of concentrated European process technology becoming a trade instrument: the Netherlands' restriction of ASML EUV and later DUV exports to China — imposed under US pressure and formalised through Dutch licensing in 2023 — is the clearest example of a European equipment monopoly being weaponised.

This is the chain's tightest chokepoint and the constraint Wood Mackenzie explicitly names as the cause of the projected ~195% turbine price increase to ~$600/kW by 2027. Single-crystal casting grows an entire turbine blade as one crystal with no grain boundaries, using directional solidification through a helical grain selector in a vacuum furnace, over a wax pattern and ceramic core assembly whose internal cooling geometry is itself proprietary. Yields on a new part number can begin below 50%. The know-how is the accumulated furnace-recipe and core-design library, plus a workforce of foundry technicians that takes years to train. Critically, the listed-only view understates true concentration: privately-held Precision Castparts (owned by Berkshire Hathaway, editorially sourced at approximately 35-40%) means Howmet and PCC together hold roughly 80%-plus of the segment.

Very high. This capability has not been successfully replicated by a new Western entrant in decades despite continuous OEM interest in a third source. Building a qualified single-crystal foundry requires the furnaces, the core supply, the process library (not available) and the qualification campaigns (five-plus years). The March 2026 reporting on specialised labour shortages is not incidental to this segment; it is the binding input that cannot be resolved by a groundbreaking ceremony.

Four distinct threats. First, OEMs are actively funding alternatives — CMC and additive manufacturing — precisely to escape this dependency, a dynamic distinct from coating equipment where OEM in-house capability is only partial. Second, aerospace and power draw on the same foundry capacity, so a commercial aerospace upcycle directly crowds out power-generation blade supply: a demand risk disguised as a strength. Third, concentration invites customer-driven intervention: widely reported pressure on aerospace suppliers following quality events showed that when a supply chain becomes both concentrated and critical, regulators and prime customers impose oversight and cost that erode the pricing benefit of scarcity. Fourth, and specifically Howmet-relevant: at 40% listed share against a private holder of similar size, Howmet does not set price unilaterally.
