What is Alubum (Aluminium Composite Material)?

Aluminium Composite Material, or alubum, is a panel consisting of two thin aluminium sheets bonded to a non-aluminium core. This core is typically made of polyethylene (PE) or a fire-retardant mineral-filled material. The resulting sandwich-like structure provides exceptional rigidity and strength while remaining remarkably lightweight. The aluminium surfaces can be coated with various finishes, offering a wide array of colors, textures, and protective properties. This versatility contributes significantly to the widespread adoption of alubum in modern construction.

Composition of Alubum Panels

Understanding the individual components of alubum is essential to appreciating its overall performance:

Aluminium Sheets: These are typically made from aluminium alloys, chosen for their strength, corrosion resistance, and formability. The thickness of the aluminium sheets can vary depending on the application and desired performance characteristics.
Core Material: The core material provides the bulk of the panel’s thickness and contributes to its rigidity and insulation properties. PE cores are common for general applications, while fire-retardant (FR) cores are mandated for many high-rise buildings and projects with stringent fire safety requirements.
Surface Coating: The outer surfaces of the aluminium sheets are typically coated with a protective finish, such as polyvinylidene fluoride (PVDF) or polyester paint. These coatings provide color, UV resistance, and protection against weathering and corrosion.
Adhesive Layer: A specialized adhesive is used to bond the aluminium sheets to the core material, ensuring a strong and durable connection.
