3004-H19 Aluminum

3004-H19 is a high-strength aluminum alloy, belonging to the aluminum-manganese series (3000 series), containing manganese (Mn) and magnesium (Mg). In the H19 condition, it undergoes strain hardening to achieve higher strength. This makes 3004-H19 have superior mechanical properties compared to other heat-treated conditions of 3004 alloy (such as H18, H16, etc.), making it especially suitable for applications requiring higher strength.

3004-H19 Aluminum Chemical Composition

The primary alloying elements of 3004 aluminum are manganese (Mn) and magnesium (Mg), giving it excellent corrosion resistance and high strength. Its typical chemical composition is as follows:

Aluminum (Al): Main component, approximately 97.4%-99.0%.
Manganese (Mn): 1.0%-1.5%.
Magnesium (Mg): 0.3%-1.2%.
Copper (Cu): 0.05%-0.20%.
Silicon (Si): Less than 0.6%.
Iron (Fe): Less than 0.7%.

3004-H19 Aluminum Alloy Properties

Strength: In the H19 condition, 3004 aluminum alloy undergoes strength hardening treatment, giving it very high strength, at least 10 MPa (or 1.5 ksi) higher than in the H18 condition. This makes it more advantageous than other conventional 3004 alloys (such as H18, H16, etc.), especially in applications requiring higher strength.
Corrosion Resistance: 3004 aluminum alloy exhibits excellent corrosion resistance, especially in atmospheric and seawater environments. Due to the addition of manganese and magnesium, it has strong resistance to moisture, salt spray, and chemical environments.
Formability: 3004-H19 alloy has high strength due to cold processing (stretching), making it suitable for deep drawing, stretching, and other processing methods. However, due to its hardened properties, its ductility is relatively low, which is not as good as soft aluminum alloys. Therefore, in some applications requiring high ductility, proper control of operating conditions is needed.
Weldability: Although 3004 aluminum alloy has certain weldability (particularly suitable for gas shielded welding and spot welding), due to the higher strength in the H19 condition, welding should be controlled to prevent performance degradation in the heat-affected zone and to avoid welding heat cracks.

3004-H19 Aluminum Compared to Other Conditions

Differences Between 3004-H18 and 3004-H19

3004-H19 has higher strength than 3004-H18, making it suitable for higher load applications, but its ductility is lower.

Compared to the H19 condition, 3004-H18 has better ductility, making it more suitable for forming processes that require higher plasticity, such as deep drawing, but its strength is lower.

Applicability of the H19 condition: 3004-H19 is suitable for applications that require higher strength but have relatively low demands for ductility. For structural components or containers that need high strength and corrosion resistance, the H19 condition is an ideal choice.

3004-H19 Aluminum Processing and Heat Treatment

Processing: 3004-H19 aluminum alloy is suitable for forming processes such as stretching and deep drawing, but due to its higher hardness, it requires higher pressure or processing speeds. Additionally, lubricants or special tools may be needed during processing to reduce surface damage.
Heat Treatment: 3004 aluminum alloy is mainly hardened through cold working to achieve different tempers, such as H19. Due to the high strength of this alloy, further heat treatment is usually not needed to enhance hardness, but annealing can be used to adjust its properties.
