Major Individual Company Purchasers

• GE Aerospace: Likely the world's largest individual purchaser; hafnium is critical for the "LEAP" and "GE9X" engines to increase fuel efficiency through higher operating temperatures.
• Intel Corporation: A dominant purchaser for the semiconductor sector; Intel pioneered the use of "hafnium-based high-k dielectrics" to prevent leakage in nanometer-scale transistors.
• Rolls-Royce Holdings: A massive consumer of hafnium-rich superalloys for its commercial and military jet engines (e.g., the Trent family).
• Raytheon Technologies (Pratt & Whitney): Consumes significant hafnium for the turbine sections of the F135 (F-35 Lightning II) and commercial geared turbofan engines.
• Westinghouse Electric Company: A primary purchaser for the nuclear sector, utilizing hafnium in reactor control assemblies for long-term neutron absorption.
• TSMC (Taiwan Semiconductor Manufacturing Co.): Procures hafnium-based precursors for the production of advanced 3nm and 2nm chips.
• ATI (Allegheny Technologies Inc.): A key mid-stream purchaser that buys hafnium to create the specialized superalloys they sell to Boeing and Airbus.
• Framatome: A French nuclear giant that purchases hafnium for fuel and control systems in European reactor designs.
• ASML: Indirectly drives demand as their lithography machines are the only tools capable of depositing hafnium layers at the precision required for modern CPUs.
• Safran S.A.: A major French aerospace purchaser involved in the joint development of turbine engines and military defense systems.
