Technical Specifications and Applications of Aluminium Couplings

Our aluminium couplings are designed to provide reliable connectivity in various piping systems, including those used in construction, automotive, and marine industries. Made from grades such as Aluminium 6061 and 6082, these couplings offer exceptional resistance to corrosion and high tensile strength, making them suitable for environments where both durability and light weight are essential. Applications range from industrial pipelines to structural projects where high resistance to pressure and corrosion is necessary. The pricing of these couplings varies depending on factors such as grade, size, and customization requirements, with Aluminium 6061 offering an affordable, high-quality solution compared to higher-grade options.
