Materials Autonomy

magnets · graphite · gallium · copper

Every robot, robotaxi, charger and data center rests on a short list of refined materials, and China processes most of them. The chokepoint is refining and magnet making, not the mine.

Bar chart of China's share of global output: polysilicon about 95%, graphite anode refining 94%, primary gallium about 98%, NdFeB magnets about 90%, magnet rare earth refining 84%, cobalt refining 76%, lithium refining 74%, rare earth mining about 69% and copper refining 47%. A dashed line marks 50%; all but copper are above it.

Finding

Materials autonomy is decided at the refinery and the magnet plant, where China holds most of the world's capacity and now licenses exports

Ore is mined on every continent, but conversion is concentrated: China refines 94% of battery graphite, about 84% of magnet rare earths and makes about 90% of NdFeB magnets. Since 2023 Beijing has put gallium, germanium, graphite, antimony and seven medium and heavy rare earths under export licensing, which turns concentration into a policy lever.

The April 2025 rare earth licensing round showed what that lever does: within weeks, Ford idled its Chicago Explorer line and European suppliers warned of motor and actuator stoppages because dysprosium- and terbium-bearing magnets stopped clearing customs. The October 2025 expansion was suspended for a year after the November 2025 US-China trade truce, but the licensing system itself stays in place.

Materials sit at the base of the Six Foundation Domains because every layer above them is built from these inputs: silicon needs polysilicon and gallium, energy needs lithium, graphite, copper and grain-oriented electrical steel, and every motor and actuator needs NdFeB magnets. The Western response is building out now: MP Materials is ramping magnet output at its Fort Worth plant under a July 2025 Department of Defense deal with an NdPr price floor, and Tesla runs its own lithium hydroxide refinery near Corpus Christi.
