Aluminium Foils
Product Overview
Aluminium Foils supplied by R V Metal Corporation are manufactured from high-purity aluminium and aluminium alloys, offering excellent barrier properties, formability, corrosion resistance, and thermal conductivity. These foils are available in a wide range of thicknesses, tempers, and surface finishes to suit industrial, packaging, pharmaceutical, HVAC, electrical, insulation, and food-grade applications. Depending on the grade and temper, aluminium foils provide superior resistance to moisture, light, gases, and contaminants while maintaining lightweight characteristics and ease of fabrication. R V Metal Corporation offers aluminium foils in soft (O), half-hard (H12/H14), and hard tempers, with options for plain, laminated, coated, or embossed finishes, supplied in coils or cut-to-size formats with full material traceability and compliance to international standards.
