What does H18 mean in 3004 Aluminum?

In the context of 3004 aluminum, the temper designation "H18" indicates the alloy's specific heat treatment process and resulting mechanical properties.

3004-H18 aluminum is 3004 aluminum in H18 condition. This is the strongest temper usually produced by strain hardening action alone.

3004 H18 aluminum plate also belongs to the aluminum-manganese alloy series. It has higher strength, excellent formability and good corrosion resistance than 3003, and it requires parts with higher strength than 3003 alloy.

For 3004 aluminum, the H18 temper indicates that the material has been strain-hardened and subjected to a controlled annealing process. Here's what H18 means for 3004 aluminum:

• Strain hardening (H): The "H" in H18 stands for strain hardening, which involves the plastic deformation of aluminum alloys to increase their strength. For 3004 aluminum, the material is usually cold-worked by processes such as rolling or drawing to induce strain hardening.
• High Strength (18): The number "18" after the H indicates high strain hardening and high strength. H18 tempering significantly increases the mechanical strength of 3004 aluminum alloy.

3004 H18 aluminum plates are mainly used in chemical product production and storage devices, thin plate processing components, building materials, building baffles, cable ducts, sewers, various lighting components, beverage cans, corrugated plates, building materials, colored aluminum plates, and lamp heads.

Mechanical properties: Tensile strength σb (MPa): 150～285 Elongation δ10 (%): 1～16 Annealing temperature: 415℃

Properties of 3004 H18 Aluminum Plate

• Reaction with Acids: Aluminum reacts with strong acids, such as hydrochloric acid (HCl) or sulfuric acid (H2SO4), resulting in the production of hydrogen gas and the dissolution of the aluminum surface. However, in practical applications, 3004 aluminum is often coated or treated to protect it from such reactions.
• Reaction with Alkalis: Aluminum is generally resistant to alkalis, including sodium hydroxide (NaOH), at room temperature. However, prolonged exposure to strong alkalis can lead to aluminum corrosion.
• Oxidation Resistance: Aluminum alloys like 3004 are highly resistant to oxidation at normal temperatures, thanks to the formation of a naturally occurring oxide layer on their surfaces.
• Interactions with Other Metals: In contact with certain dissimilar metals (e.g., copper or steel), aluminum can experience galvanic corrosion due to differences in electrode potential. Proper insulation or coatings may be necessary to prevent galvanic corrosion in specific applications.
• Flammability: Aluminum and its alloys are non-combustible and do not support combustion. This property makes them suitable for applications where fire resistance is important.
• Chemical Stability: Aluminum alloys, including 3004, are chemically stable in many environments, making them suitable for a wide range of industrial applications.
• High Tensile Strength: The H18 temper can significantly increase the tensile strength compared to softer tempers.
• Increased hardness: H18 aluminum has a higher hardness, making it more resistant to deformation and wear.
• Reduced ductility: While the H18 temper increases strength, it may slightly reduce the ductility and formability of the alloy compared to soft tempers.
• Formability: 3004 H18 aluminum retains a reasonable level of formability, but it may require more force or specialized forming techniques than softer tempers.
• Corrosion Resistance: H18 tempering does not significantly affect the inherent corrosion resistance of 3004 aluminum.

The specific mechanical properties of 3004 H18 Aluminum, such as tensile strength, yield strength, elongation, and hardness, may vary depending on the manufacturing process and specific requirements. For accurate information on the mechanical properties of 3004 H18 Aluminum, it is recommended to consult the manufacturer or supplier.

3004 h18 Aluminum Plate vs 3004 h19 Aluminum Plate

Temper Condition

H18 and H19 refer to different heat treatment conditions of aluminum sheets.

• 3004 H18: H18 indicates a high degree of strain hardening and subsequent annealing. The material is strain-hardened and then subjected to a controlled annealing process.
• 3004 H19: H19 also represents a high degree of strain hardening, but is not subjected to the same annealing process as H18. It is mainly achieved by cold working to achieve the required hardness and strength.

Strength

Tempering conditions affect the strength of the aluminum sheet.

• 3004 H18: The H18 temper provides high strength due to a combination of strain hardening and annealing. Compared with H19, it has higher tensile strength and yield strength.
• 3004 H19: The H19 temper also provides good strength, but may be slightly lower compared to H18 due to the lack of an annealing process.

Ductility and Formability

Tempering conditions affect the ductility and formability of aluminum sheets.

• 3004 H18: Due to the strain hardening and annealing process, the ductility of the H18 temper may be slightly reduced compared to H19. However, it still retains good formability for various applications.
• 3004 H19: H19 tempers generally provide higher ductility and formability than H18. It is easier to bend and form for applications requiring complex shapes or tight bends.

Application

H18 and H19 aluminum sheets have their respective applications based on their mechanical properties and formability.

• 3004 H18: The H18 plate is commonly used in applications requiring high strength and moderate formability, such as automotive body panels, building components, and heat exchangers.
