The main element of 3105 aluminum closure sheet plate is Al-Mn. On the basis of 3003 aluminum alloy, some Cu and Mg are added to increase the mechanical properties of 3105 aluminum plate. This alloy has higher strength than 3003 alloy aluminum plate; Compared with 8011 aluminum closure sheet plate, the strength of 3105-H14/H16 aluminum closure sheet plate can withstand sufficient gas pressure. It is widely used to make screw caps for gas and liquid bottles such as soda drinks and carbonated wine.
Our factory controls material composition, rolling temperature and time, annealing temperatures to produce the best material to meet our customers’ performance needs. Flait Aluminum provides 3105 aluminum closure sheet plate for screw caps with good tensile properties, yield strength and corrosion resistance. The surface is free of oil stains, dents, inclusions, scratches, stains, oxide discoloration, breaks, corrosion, and rolling marks. Also, we can perform phosphate chromate treatment and DOS coating treatment on 3105 aluminum closure sheet plate for screw caps, and print different colors on the basis of our aluminum plates.
