If you need a versatile and highly workable aluminum material for your next project, GNEE 3003 H14 aluminum is an excellent option. Thanks to its outstanding corrosion resistance and reliable workability, this temper is widely used in food and chemical processing equipment, heat exchangers, storage tanks, and roofing applications.
Aluminum alloys in the 3000 series are primarily alloyed with manganese, and 3003 aluminum follows this same principle. The combination of aluminum and manganese produces a moderate-strength alloy that delivers excellent corrosion resistance along with good forming and fabrication performance. These balanced characteristics make 3003 aluminum one of the most commonly used aluminum alloys in the industry.
The H14 temper indicates that 3003 aluminum has been strain-hardened to increase strength, followed by partial annealing to reduce internal stress and minimize the risk of cracking. Compared with H12, H14 provides higher strength but slightly reduced formability, while remaining more formable and less rigid than H18.

Chemical Composition
GNEE 3003 H14 aluminum consists mainly of aluminum, with several alloying elements that contribute to its performance. The principal elements typically include:
Aluminum (Al): 96.7%–99%
Manganese (Mn): 1.0%–1.5%
Copper (Cu): 0.05% – 0.20%
Pure aluminum is valued for its high strength-to-weight ratio and excellent corrosion resistance. The addition of manganese further enhances these properties, while copper contributes additional strength.
Mechanical Properties
Selecting the right material requires careful consideration of mechanical properties, as they directly affect performance and suitability for specific applications. Typical mechanical properties of GNEE 3003 H14 aluminum include:
Density: 2.73 g/cm³
Tensile Strength: 130–180 MPa
Yield Strength: 115 MPa
Elongation: 10–12%
Hardness: 40 HB (Brinell)
Modulus of Elasticity: 70 GPa
Melting Point: 643–654°C
The combination of low density and good elasticity makes 3003 H14 aluminum ideal for fabricated components where weight reduction is important. Its favorable elongation, together with moderate tensile and yield strength, provides dependable structural performance.
Physical Properties
The most notable physical characteristics of GNEE 3003 H14 aluminum include excellent formability, strong resistance to corrosion, and a high strength-to-weight ratio. This lightweight alloy performs well in chemically aggressive or outdoor environments and can be easily bent, drawn, or shaped to meet a wide range of design requirements.
