3003 aluminum sheet is a common aluminum-manganese alloy material. Below is a detailed introduction to its chemical composition, mechanical properties, and application fields:
I. Chemical Composition
Main component: Primarily aluminum (Al), with the balance being aluminum.
Alloying elements:
Manganese (Mn): Usually 1.0%～1.5%, a key element for improving the alloy's strength and corrosion resistance.
Silicon (Si): Approximately 0.6%.
Copper (Cu): 0.05%～0.2%.
Iron (Fe): Not exceeding 0.7%.
Zinc (Zn): Approximately 0.10%.
Other impurity elements: Each individual impurity content ≤0.05%, total impurity content ≤0.15%.
II. Mechanical Properties
Tensile strength: In annealed state, the tensile strength is usually 120MPa～180MPa, with specific values slightly fluctuating due to differences in production processes and compositions.
Yield strength: The proof yield strength (σ0.2) is generally ≥85MPa. The yield strength increases in the half cold-worked hardened state, and further increases after cold-worked hardening while ductility decreases.
Elongation: Higher in annealed state, generally 15%～35%. The elongation is acceptable in the half cold-worked hardened state, and significantly decreases after cold-worked hardening.
Hardness: Hardness can be improved through cold working or appropriate heat treatment, but the effect of heat treatment strengthening is limited. Strength and hardness are mainly enhanced through cold-worked hardening.
III. Application Fields
New Energy Vehicle Field: Used for manufacturing battery cases, battery covers, automotive water-cooled plates and other components. Its good thermal conductivity, corrosion resistance, and formability ensure battery safety and heat dissipation performance.
Solar Photovoltaic and Wind Power Generation Fields: Applied in manufacturing solar photovoltaic panel frames, wind turbine blades, etc. With high strength, corrosion resistance, and thermal conductivity, it adapts to harsh outdoor environments.
Energy Storage Field: Used for energy storage battery enclosures, structural parts, etc. It meets the requirements of lightweight, high strength, corrosion resistance, and heat dissipation, in line with the concept of green environmental protection.
Construction Field: Utilized for building curtain walls, door and window frames, decorative strips, etc. It has good corrosion resistance and an attractive appearance, suitable for humid or corrosive environments.
Electronic and Electrical Field: Used for electronic device casings, radiators, circuit board brackets, etc., balancing electrical conductivity, corrosion resistance, and processability.
Chemical and Food Industry: Applied in chemical equipment, storage tanks, pipelines, food processing equipment, etc. Its corrosion resistance allows it to adapt to corrosive media such as acids, alkalis, and salts.
Transportation Field: Used for automotive body components, rail vehicle doors and windows, ship materials, etc., achieving lightweight design while ensuring structural strength.
Aerospace Field: Utilized for aircraft skins, skeletons, and other structural parts, meeting the requirements of high strength, corrosion resistance, and lightweight.
Daily Necessities Field: Used for manufacturing kitchenware, tableware, aluminum lunch boxes, honeycomb cores, etc., leveraging its good formability and corrosion resistance.
