The primary end-uses of Aluminum span multiple sectors, each contributing to its classification as a critical material. The following applications represent the most significant sources of global demand:

• Transportation and automotive — Aluminum plays a vital role in transportation and automotive, where its unique physical and chemical properties provide performance advantages that are difficult to replicate with alternative materials.
• Packaging and containers — Aluminum plays a vital role in packaging and containers, where its unique physical and chemical properties provide performance advantages that are difficult to replicate with alternative materials.
• Construction and building materials — Aluminum plays a vital role in construction and building materials, where its unique physical and chemical properties provide performance advantages that are difficult to replicate with alternative materials.
• Electrical transmission lines — Aluminum plays a vital role in electrical transmission lines, where its unique physical and chemical properties provide performance advantages that are difficult to replicate with alternative materials.
• Aerospace components — Aluminum plays a vital role in aerospace components, where its unique physical and chemical properties provide performance advantages that are difficult to replicate with alternative materials.

Sector Breakdown

The largest consuming sector for Aluminum is transportation and automotive, which accounts for a substantial share of global demand. The second most significant application is packaging and containers, which has shown strong growth in recent years driven by technology adoption and regulatory requirements. Emerging applications across clean energy, defense, and advanced manufacturing are expected to expand the demand profile for Aluminum in the coming decade.

Demand Outlook

With a criticality level of medium and a supply risk rating of low, the demand trajectory for Aluminum is closely monitored by governments and industry analysts. Its inclusion on the USGS critical minerals list underscores the strategic importance of securing stable supply for domestic industries. The European Union has similarly recognized its importance through inclusion on the EU Critical Raw Materials list. Growing demand from electrification, digitalization, and defense modernization programs is expected to place additional pressure on existing supply chains.
