Product Category: Billet
Series:
Nam Sung Aluminium supplies a comprehensive range of aluminium billet alloys, including 6063, 6061, 6005, 6463, and other grades, with diameters ranging from 3.5 inches to 8 inches. Designed to meet the diverse requirements of extrusion manufacturers, our billets are widely used in both architectural and industrial aluminium applications.
Supported by advanced manufacturing equipment, integrated production lines, and a rigorous quality management system, Nam Sung maintains an annual billet production capacity of approximately 35,000 metric tons, ensuring a stable and reliable supply for both domestic and international markets.
Nam Sung billets are manufactured in accordance with internationally recognized standards, including ASTM B221 and JIS H4100:2015. Strict control of alloy composition, mechanical properties, and surface quality ensures consistent performance and compliance with demanding technical requirements across modern construction and industrial sectors.
Produced from high-purity imported aluminium ingots and carefully selected alloying elements such as magnesium (Mg), silicon (Si), copper (Cu), titanium (Ti), and chromium (Cr), Nam Sung billets are engineered to achieve optimal strength, durability, and processing stability.
The melting and casting process is closely controlled within a temperature range of 660°C to 730°C. Multiple filtration and refining stages are applied to remove impurities before casting, resulting in homogeneous round billets with superior metallurgical quality.
Through stringent quality control at every stage of production, Nam Sung billets deliver high purity, excellent surface quality, and reliable extrusion performance, making them an ideal choice for manufacturers of architectural and industrial aluminium profiles.
Backed by more than a decade of manufacturing experience, Nam Sung Aluminium supplies high-quality aluminium billets in a wide range of sizes and alloy grades to support diverse extrusion and industrial applications.
