Tantalum Foil in the Aerospace Sector

High-temperature-resistant tantalum foil supports lightweight equipment upgrades. The aerospace sector accounts for 20% of global tantalum foil demand. As equipment evolves toward lightweighting and high reliability, specialty tantalum foil has become a key material. Current breakthroughs in tantalum foil technology focus on adaptability to extreme environments and structural optimization.

A major breakthrough has been achieved in high-temperature tantalum foil. By adjusting the alloy ratio and improving the rolling process, the new tantalum foil can maintain stable electrical conductivity and mechanical properties at temperatures up to 500°C, increasing the temperature limit by 200°C compared to traditional products. It has been used in the lining of heat exchangers in spacecraft propulsion systems. In radar systems, capacitors using nano-tantalum foil are 40% smaller and have an energy density of 15J/cm³, meeting the miniaturization requirements of airborne equipment.

The modernization of military equipment is further driving demand. It is estimated that demand for tantalum foil in the military sector will reach 10,000 tons by 2025, a 4% annual increase. On the technical level, the company is developing "ultra-thin + high-strength" composite tantalum foil, which uses flash cladding technology to achieve a balance between a thickness of less than 10μm and a tensile strength of 300MPa, making it suitable for new equipment such as drones and hypersonic weapons.
