Highlights
- Platinum group metals powering aerospace and defense systems
- Expanding role in hydrogen and clean energy innovations
- Supply deficit outlook shaping long-term demand
Platinum group metals (PGMs) are becoming increasingly vital across aerospace and defense industries, where advanced materials are essential for innovation. While rare earth elements often capture headlines, platinum, palladium, rhodium, iridium, and ruthenium are steadily gaining traction in critical technologies. This rising demand is drawing attention from global markets, aligning with broader interest in resources tied to the ASX 200 index.
Aerospace and Defense Applications
Platinum has become an essential component for defense technology, supporting systems such as catalytic converters in military vehicles that help reduce detection from heat-seeking systems. It is also used as a catalyst in advanced fuel reforming for power units and in protective plating for turbine blades.
In aerospace, platinum combines with rhodium for temperature-sensing applications in engines, while iridium is applied in missile nose cones due to its heat-resistant properties. Palladium continues to play a role in high-specification capacitors, and ruthenium is being adopted in chip resistors for critical electronic components.
Expanding Role in Hydrogen Innovations
The defense sector is also exploring hydrogen applications where PGMs are indispensable. Hyundai Rotem (KRX:064350), a subsidiary of Hyundai Motor Company, is working on the development of a hydrogen-powered military tank, marking a step forward in clean-energy defense mobility. Meanwhile, the U.S. Department of Defense is advancing hydrogen generation and storage systems for naval operations, exploring a tactical hydrogen supply chain supported by Proton Exchange Membrane electrolysis.
Market Outlook and Supply Considerations
Growing demand is accompanied by tightening supply conditions. Industry bodies project sustained deficits in platinum availability over the coming years, which is expected to strengthen long-term demand across both defense and industrial use cases. Palladium also faces supply challenges, though its outlook may transition over time.
The balance between expanding technological applications and constrained supply is positioning PGMs as a strategic asset, reinforcing their importance not just in industrial sectors but also in global defense and aerospace strategies.
