Aluminum

Aluminum (Al) is a lightweight, versatile metal known for its excellent corrosion resistance, high ductility, and exceptional conductivity. With a melting point of 660.3 °C and a silvery-white appearance, aluminum is the most abundant metallic element in the Earth’s crust. Despite its low density, it exhibits high strength when alloyed, making it indispensable in applications requiring weight reduction. It naturally forms a protective oxide layer, enhancing its durability in harsh environments. Aluminum is non-magnetic, non-sparking, and highly reflective, with outstanding thermal and electrical conductivity. Its ease of fabrication through casting, extrusion, and rolling contributes to its widespread use in aerospace, automotive, construction, packaging, electronics, and beyond. From commercially pure grades to advanced aerospace alloys, aluminum plays a pivotal role in modern engineering and scientific innovation.

Goodfellow’s comprehensive Aluminum (Al) product range, including 1050 and 1070 Aluminum Foils, Aluminum Sputtering Targets, Aluminum Rods, and Aluminum Powders, supports high-performance laboratory research requirements as well as aerospace, automotive, and electronics applications. Aluminum is renowned for its lightweight, corrosion-resistant, and highly conductive properties, making it essential for advanced materials and precision manufacturing. Aluminum is used broadly in science and technology research, including in energy storage systems, semiconductor research, and thin-film technology. Our high-purity Single Crystal Aluminum products support materials science, nanotechnology, and advanced manufacturing. These products help drive progress in solar energy, battery development, and semiconductor fabrication, supporting next-generation technologies.
