Who makes critical minerals for AI data centers
A group of minor metals — gallium, germanium, indium, tungsten and beryllium — used in semiconductors, optics, thermal interface materials and specialty alloys, with supply concentrated in China and subject to export controls.
Each of these five elements plays a narrow but hard-to-substitute role somewhere in the chain: gallium in compound-semiconductor power devices and substrates, germanium in infrared optics and certain fiber and detector applications, indium in solder and thermal-interface materials used at the chip and cold-plate interface (Layers 1, 5), tungsten in high-density and high-melting-point alloys, and beryllium in specialty alloys and RF components. What ties them together for an investor is not end use but supply structure: production, and especially refining, of several of these elements is concentrated in China, and export licensing requirements have periodically restricted shipments, creating a supply risk that is geopolitical rather than geological. Reserves of gallium, germanium and indium in particular exist more widely than current refining capacity does, so the near-term constraint is processing capacity and trade policy rather than resource scarcity. AI hardware is a small but growing draw on this group, mainly through power semiconductors, optics and thermal-interface-material formulations rather than bulk consumption. For investors, this is a policy-and-substitution watch: export-control announcements, the pace of non-Chinese refining capacity coming online, and how quickly device makers qualify substitute materials or alternative chemistries where possible.
AI delta: AI hardware adds a growing draw on this group through compound-semiconductor power devices, optics and thermal-interface formulations, layering additional demand onto a supply base already concentrated and subject to export licensing.
