Aluminium Bars
Product Overview
R V Metal Corporation supplies aluminium bars in a wide range of grades and tempers for engineering, fabrication, marine, aerospace, and general industrial use. Our aluminium bar stock is available as round bars, square bars, flat bars, and hex bars in mill finish or with processing options such as precision cutting, peeling/turning, and surface finishing as per requirement. Common alloys include 1xxx (commercially pure), 2xxx (high strength), 5xxx (marine), 6xxx (structural/extrusion), and 7xxx (aerospace-grade strength), selected based on corrosion resistance, machinability, weldability, and strength targets. We support cut-to-length supply, batch traceability, and mill test certificates for consistent quality across domestic and export projects.
