A7 Aluminum Ingots High Purity ≥99.7% Electrical Thermal Conductive for Industrial and Manufacturing Use

A7 aluminum ingots are high-purity primary aluminum ingots conforming to Russian standards, with an aluminum content ≥99.7%, strictly controlled impurities, and stable composition. They have a silvery-white metallic luster, are mostly trapezoidal/rectangular in shape, and weigh 20-25 kg per ingot for easy transport. They possess excellent electrical and thermal conductivity as well as machinability, and can be processed into various shapes through melting, extrusion, and other processes. They are widely used in aluminum alloy production, automotive parts, building curtain walls, electronic components, and food packaging.
