Aluminum Copper alloy granules are high-performance materials engineered for demanding metallurgical and thin-film applications. Their uniform particle size, low gas content, and excellent thermal and electrical conductivity make them suitable for both industrial production and advanced R&D. We offer customizable compositions and particle sizes to meet specific needs, along with comprehensive after-sales support—please feel free to contact us if you have any questions regarding its use.
We offer AlCu alloy granules in various standard compositions such as Al-2wt%Cu, Al-4wt%Cu, and Al-8wt%Cu, and also support custom formulations. Each batch is produced using high-purity raw materials and precision-controlled melting techniques to ensure consistency, cleanliness, and excellent performance.
