Redefining Magnetics, Securing European Autonomy

EU Magnet Dependency Crisis

EU relying on a single source for 100% of its heavy REEs and 98% of finished magnets.

Vital sectors like defense and renewables are exposed to severe financial instability and geopolitical risk.

The EU Critical Raw Materials Act (CRMA) now legally mandates that European OEMs de-risk their supply chains.

Aethirite’s Iron Nitride Technology

We utilize the α′′−Fe₁₆N₂ Iron Nitride phase—the only non-rare-earth compound with the intrinsic ability to surpass NdFeB magnets.

Secure Strategic Autonomy

Superior Thermal Stability

Performance without Compromise

Utilizing a 100% domestic, rare-earth-free supply chain.

10x more stable and 2x the operating temperature than Nd

Potential to 2x the Max Energy Product of best Nd magnets

Key Benefits for European OEMs

Sustainable Synthesis

Manufacturing process using non toxic Earth-abundant materials

Aethirite's Core Innovation

While Iron Nitride's potential has long been recognized, industrialization stalled because unstable lab samples proved difficult to mass-produce. Aethirite’s vertical integration, spanning from raw iron ingots to finished magnets, aims to bridge this critical "scale-up gap".

Powder - Gas Atomization: Raw Building Blocks

Nitriding: Magnetic Precursor

Magnetic Alignment: Enhance Magnetics

Spark Plasma Sintering: Near-netshape Magnet

Ultra-pure iron and shatter it into a microscopic mist of metal using high-velocity nitrogen gas.

The powder is gently "soaked" in a specialized nitrogen stream at low temperatures. Nitrogen atoms moving into the iron lattice

Apply a powerful external magnetic field to the mold ensuring all magnetic power is concentrated in one direction.

Lightning-fast pulse of electricity and high pressure to fuse the powder into a solid block in minutes
