Product Forms and Descriptions
3003 Sheet & Plate
GNEE 3003 aluminum sheets and plates are among the most commonly used product forms. They are available in a wide range of thicknesses, from ultra-thin foil gauges to medium-thickness plates measuring several millimeters. With excellent formability, moderate strength, and outstanding corrosion resistance, these products are widely applied in roofing systems, wall cladding, cookware, decorative panels, and industrial enclosures. 3003 aluminum sheet is easy to cut, stamp, bend, and weld, making it ideal for lightweight structural applications that require both durability and flexibility.
3003 Aluminum Foil
GNEE 3003 aluminum foil offers superior ductility and flexibility, making it widely used in packaging, insulation, and interior decorative applications. Its strong resistance to moisture and oxidation, combined with good surface printability, makes it an excellent choice for food, pharmaceutical, and cosmetic packaging. Embossed or color-coated 3003 foil is also used in decorative panels, providing both visual appeal and protective performance.

3003 Extruded Profiles
GNEE 3003 aluminum extrusions include angles, channels, tubes, and other custom profiles. This alloy provides good extrudability and ductility, allowing the production of complex cross-sectional shapes. These profiles are commonly used in building structures, decorative frames, machinery supports, and furniture components. Their lightweight nature and strong corrosion resistance make them suitable for long-term use in both indoor and outdoor environments.
3003 Aluminum Tubes & Ducting
GNEE 3003 aluminum tubes and ducting are available in round, rectangular, oval, and spiral-wound configurations. They are widely used in HVAC systems, ventilation equipment, automotive piping, and lightweight structural engineering. With excellent formability, low weight, and strong corrosion resistance, 3003 aluminum tubes improve airflow efficiency and extend service life, making them essential materials in energy-efficient buildings and industrial piping systems.

GNEE 3003 Aluminum Tempers
GNEE 3003 aluminum is supplied in a range of tempers, from fully annealed to work-hardened conditions, to meet different requirements for strength and formability.
O (Annealed)
The O temper is fully annealed, offering maximum softness, ductility, and formability. It is ideal for deep drawing, bending, and complex forming processes, such as cookware, roofing panels, and decorative components. While its strength is relatively low, it provides excellent processing flexibility.
H14 (Half-Hard)
3003 aluminum in the H14 temper is produced through work hardening and offers higher strength than the O temper while maintaining good formability. It is commonly used in architectural panels, ceilings, louvers, and automotive body components where moderate strength and reliable processing performance are required.
H24 (Cold Worked and Partially Annealed)
The H24 temper is achieved through cold working followed by partial annealing. It provides a balanced combination of strength and ductility, with mechanical properties between O and H14 tempers. This makes it well suited for gutters, downspouts, packaging containers, and heat exchanger components that require both formability and structural stability.
