ADVANCED MATERIALS & FLIGHT COMPONENTS
BUILT FOR THE VOID
SpaceSail engineers the alloys, composites, and precision hardware that survive launch, hard vacuum, and fifteen years of orbital night. If it flies, something of ours is probably holding it together.
Certifications: AS9100D certified, Nadcap accredited, ISO 9001:2015, ITAR registered, ECSS compliant, NASA-STD-6016 approved, MIL-SPEC QPL listed, ISO 7 cleanroom operations.
SEC.01 // DOCTRINE
The void does not negotiate.
Every gram must justify itself. Every joint must hold through 14 g of launch vibration, then keep holding through three hundred degrees of thermal swing, ninety minutes at a time, for fifteen years.
At −180 °C, ordinary metals turn glass-brittle. In hard vacuum, polymers exhale their plasticizers onto optics. Cold-welded fasteners seize; radiation embrittles what launch didn't crack. There is no service call at 36,000 kilometers — the part either works, or the mission ends.
SpaceSail exists for that standard. We operate nothing in orbit and sell no bandwidth — we melt, machine, laminate, and qualify matter until the physics run out of objections, then ship it, pedigree attached, to the people who do the flying.

SEC.02 // MATERIALS DIVISION
Alloys with a pedigree.
Every heat, every lot, every laminate — melted to spec, tested to destruction, and traceable back to the mill.
M-02ALUMINUM–LITHIUM
Al-Li 2195
Cryotank barrels, skins, and stringers. Five percent lighter and thirty percent stronger than the 2219 it replaced on heavy-lift tankage.
- DENSITY

- TENSILE
- 590 MPa
- SERVICE
- −253 / +120 °C
M-03CERAMIC COMPOSITE
C/C–SiC
Nozzle extensions, leading edges, and re-entry surfaces. Carbon fiber in a silicon-carbide matrix that shrugs at temperatures that melt steel.
- DENSITY
- 1.95 g/cm³
- MAX TEMP
- 1,650 °C
- CTE
- 2.6 ppm/K
M-04ENGINEERING POLYMER
PEEK CF-30
Bushings, insulators, and cable guides. Carbon-filled and vacuum-baked to outgassing limits that keep your optics clean for the whole mission.

- TML
- < 0.40 %
- CVCM
- < 0.01 %
M-05CONTROLLED EXPANSION
Invar 36

M-06RADIATION SHIELDING
Ta/PE Laminate
Graded-Z stacks of tantalum and polyethylene, tuned per orbit to cut total ionizing dose on avionics by up to seventy percent at minimum mass.
- AREAL MASS
- 1.8 g/cm²
- DOSE CUT
- up to 70 %
- FORMAT
- sheet / formed
SEC.03 // COMPONENTS DIVISION
Hardware that holds.
Flight-qualified mechanisms and structures, machined, cleaned, and lot-tested under one roof.
Release mechanisms
Shape-memory separation nuts and hinge assemblies. Sub-50 g shock, resettable on the bench, zero pyrotechnics.
SHOCK < 50 G // CYCLES > 100
Precision fasteners
A-286 and titanium hardware, dry-film lubricated against cold welding, shipped in certified lots with full material traceability.
NAS / MS SPEC // LOT-CERTIFIED
Thermal straps
Pyrolytic-graphite and copper-foil straps that move heat from focal planes to radiators without moving a single part.
k = 1,600 W/m·K // FLEX > 10⁴
Structural panels
Aluminum honeycomb cores with CFRP or aluminum facesheets, potted inserts mapped to your load points before layup.
CORE 3.1 PCF // INSERTS MAPPED
Fluid fittings
Electropolished 316L lines, fittings, and latch valves for propellant and pressurant systems, leak-checked to a billionth of an atmosphere.
He LEAK < 1×10⁻⁹ SCC/S
Isogrid structures
Core decks and cylinders machined from single billets — no joints to slip, no fasteners to shake loose, nothing to debond.
5-AXIS // ±5 µm // ONE BILLET
SEC.04 // QUALIFICATION
Qualified the hard way.
Five gates between raw metal and the launch manifest. Nothing skips a gate.
-
01
Mill certification
Every heat arrives with chemistry and mechanicals verified against spec. We re-test on receipt — trust, then verify, then keep the coupons.
-
02
Precision machining
Five-axis cells hold ±5 µm on flight surfaces. Every dimension on the drawing is measured on a CMM, not sampled.
-
03
Cleanroom integration
Assembly and precision cleaning in ISO 7, with particle counts and NVR witness plates logged against every serial number.
-
04
Environmental test
Thermal-vacuum cycling at 10⁻⁶ Torr, random vibration to 14.1 g RMS, and shock — flown on the ground before it flies for real.
-
05
Delivery with pedigree
Each unit ships with its full data package: mill certs, dimensional reports, test curves, and cleanliness records. The part's biography.

SEC.06 // CONTACT
SEND DRAWINGS. RECEIVE FLIGHT HARDWARE.
From mill certification to orbital heritage, every SpaceSail part ships with its pedigree attached. Send us your drawings — we'll send back hardware that has already survived worse than your mission profile.
Reaching the right desk. SpaceSail Industries is an independent manufacturer that supplies physical hardware — alloys, composites, structures, and mechanisms — to the organizations that build and fly spacecraft. We do not sell satellite internet, connectivity, user terminals, or network services of any kind. If that is what you need, this is not the company you are looking for.
