Cu-La alloy powder is a specialty material used as a rare earth additive in copper-based alloys to enhance mechanical strength, electrical conductivity, grain refinement, and oxidation resistance. It is applied in metallurgical processes for producing high-performance components in electronics, aerospace, and energy sectors. The lanthanum content improves thermal stability and wear resistance in applications such as electrical contacts, connectors, and coatings. Additionally, it serves as a precursor for catalysts in hydrogenation reactions and is researched for advanced materials including thermoelectrics and photovoltaic devices.
