Aluminium Ingots
Product Overview
Aluminium ingots are the primary raw material used for casting, remelting, alloying, and downstream manufacturing across automotive, electrical, construction, engineering, and foundry industries. R V Metal Corporation supplies both primary aluminium ingots produced from virgin aluminium and secondary aluminium ingots manufactured through controlled recycling processes, ensuring consistent chemical composition, clean metallurgy, and reliable performance. Our aluminium ingots are available in commercial purity and alloyed grades suitable for pressure die casting, gravity casting, extrusion billet production, rolling, and general foundry applications. Depending on grade selection, aluminium ingots offer excellent castability, good corrosion resistance, high thermal and electrical conductivity, and a favourable strength-to-weight ratio. All supplies are sourced from approved producers and are supported with material test certificates, heat traceability, and packing suitable for domestic and export requirements.
