Supply-Chain Flow
Source
Bauxite & zinc ores
China, Germany, Kazakhstan
Recovery
Gallium recovery
By-product of aluminum smelting
Refining
High-purity gallium
China dominates refining
Manufacturing
GaN / GaAs wafers & devices
Wafer and device fabrication
End Use Systems
Chips, RF, radar, telecom, space, energy
Defense, 5G, satellites, power
By-product nature means supply is tied to broader mining and refining economics, not direct demand for gallium.
Substitution Difficulty
| Use Case | Possible Substitute(s) | Tradeoff | Difficulty |
|---|---|---|---|
| RF Chips (GaN/GaAs) | Si, SiC | Lower RF efficiency, higher power loss | High |
| Power Electronics | SiC, Silicon | Cost, performance, system tradeoffs | Medium |
| LEDs / Optoelectronics | Other III-V materials | Efficiency tradeoffs | Medium |
| Solar Cells | Perovskites, Si | Efficiency, stability tradeoffs | Medium |
| Defense RF Systems | Limited alternatives | Performance risk, design rework | High |
