Metals in the New Space Economy: Who's Buying What and How Much

Launch Cadence Is Accelerating Fast

Global orbital launch attempts have nearly doubled in three years. In 2023, the world launched 180 orbital missions. In 2024, that climbed to 221. In 2025, we hit 259, and the 2026 run rate through May is tracking toward 290 or more. The driver is not government programs — it is commercial operators filling Low Earth Orbit with broadband constellations, Earth observation payloads, and in-space infrastructure.

SpaceX: The 800-Pound Gorilla of Aluminum Demand

SpaceX launched 131 Falcon 9 missions in 2025 and is on pace for 150 or more in 2026. Each Falcon 9 first stage is a 154-foot aluminum-lithium monocoque built primarily from 2219-T87 and 2195 Al-Li tankage, with 6061-T651 and 7075-T7351 in interstage, thrust structure, and grid fins. A single booster represents roughly 25,000 lbs of aluminum alloy before machining scrap. Even with booster reuse averaging 15 to 20 flights per core, SpaceX builds new boosters at a rate of 6 to 8 per year — plus upper stages, which are expendable on every mission.

Starship Changes the Scale Entirely

Starship is built from 304L stainless steel, not aluminum — but the ecosystem around it is aluminum-intensive. The launch tower, ground support equipment, payload adapters, satellite dispensers, and test infrastructure consume enormous quantities of 6061-T651 plate. SpaceX's Starbase facility in Boca Chica has become one of the largest single-site consumers of structural aluminum plate in Texas. And the Raptor engine turbopump housings, valve bodies, and fluid system components still use aerospace-grade aluminum and nickel alloys.

The Competitive Landscape: Who's Building Launch Vehicles

SpaceX dominates launch cadence, but a wave of funded competitors is scaling production. Each of these companies is placing aluminum plate orders today for vehicles that will fly in the next 12 to 36 months.

Alloy Demand by Application

Not all space-grade aluminum is the same. The application determines the alloy, and the alloy determines the supply chain complexity. Tankage alloys like 2219 and 2195 are specialty products with long lead times and limited mill capacity. Structural alloys like 7050 and 7075 are more available but still constrained in thick plate. 6061 is the universal workhorse — available, affordable, and used in enormous quantities for everything that is not primary structure.

Where Each Alloy Ends Up

The split between tankage alloys and structural alloys reflects a fundamental design boundary. Tankage must hold cryogenic propellants (liquid oxygen at -297 F, liquid hydrogen at -423 F) under pressure, demanding alloys with excellent cryogenic toughness and weldability. Structure must carry flight loads, survive vibration, and in the case of reusable vehicles, do it hundreds of times without fatigue failure.

• 2219-T87 — Propellant tank barrels and domes. The heritage NASA alloy. Excellent weldability and cryogenic fracture toughness. Used on Falcon 9 upper stage, Vulcan Centaur, and SLS.
• 2195 Al-Li — Next-generation tank alloy. 5% lighter than 2219 at equivalent strength. Used on Falcon 9 first stage (some lots), SLS core stage, and under evaluation for New Glenn.
• 7050-T7451 — Thick-plate bulkheads, thrust structures, and major machined fittings. SCC-resistant overaged temper. The go-to alloy for structural components in 2 to 6 inch plate.
• 7075-T7351 — Interstage adapters, grid fins, payload fairings, and secondary fittings. Slightly lower toughness than 7050 but more available and cheaper in thin plate.
• 6061-T651 — Ground support equipment, launch pad structures, tooling plates, test fixtures, satellite bus panels, electronics enclosures, and fluid system brackets. The 80% alloy by application count.

Projected Aluminum Demand Through 2030

Aggregating across the 40+ commercial launch and satellite companies currently in production or late-stage development, the North American commercial space sector is on track to consume approximately 8 to 12 million pounds of aerospace-grade aluminum plate per year by 2028. That is a 3x increase from 2022 levels. The growth is driven by three factors: rising launch cadence (more vehicles built per year), new entrants reaching production (Blue Origin, Relativity, Stoke, Rocket Lab Neutron), and the shift to larger vehicles (New Glenn and Starship-class).

Supply Chain Implications

The surge in space-grade aluminum demand is colliding with a domestic mill base that has not added significant rolling capacity in decades. Thick plate in 7050 (3 inches and above) already runs 12 to 20 week lead times. 2219 plate is produced by a handful of mills and routinely allocated. The new space companies are competing with defense primes for the same material from the same mills — and defense orders carry priority under DPAS ratings.

Reusability Changes the Alloy Calculus

Expendable rockets optimize for minimum weight — use the lightest alloy that survives one flight. Reusable rockets optimize for fatigue life — use the alloy that survives 100 flights without crack initiation. This shifts demand away from peak-strength 2xxx alloys toward overaged 7xxx tempers (7050-T7451, 7075-T7351) that trade 5 to 10 percent strength for dramatically better fatigue and SCC resistance. As more vehicles move to reusable architectures, expect 7050 demand to grow disproportionately.
