| O Temper (Annealed) | Fully annealed, exhibits maximum ductility and softness, suitable for deep drawing and forming processes. |
| H12 | Partially hardened temper, relatively hard but with poor formability. |
| H14 | Moderately hardened temper, with moderate strength and good formability, the most widely used temper. |
| H16 | A harder, cold-worked temper, with higher strength and average formability. |
| H18 | Highly hardened temper, with higher strength but reduced formability. |
| H22 and H24 | Rehardened to varying degrees, suitable for applications requiring higher strength. |
3003 aluminum sheets are widely used across various industries due to their excellent corrosion resistance, good formability, and moderate strength. Some of the most common applications include:
Architectural and Construction: Used for roofing, siding, gutters, and decorative panels because of its durability and resistance to weathering.
Transportation: Employed in manufacturing truck and trailer bodies, marine components, and vehicle parts due to its lightweight and corrosion resistance.
Household Appliances: Commonly used for making refrigerator panels, air conditioner housings, and other appliance exteriors.
Food and Chemical Processing Equipment: Suitable for storage tanks, piping, and chemical containers thanks to its non-toxic nature and corrosion resistance.
Industrial Applications: Used in electronic equipment enclosures, signage, and general fabrication where moderate strength and formability are required.
Overall, 3003 aluminum sheet is valued for versatility, making it ideal for applications that require good corrosion resistance combined with easy fabrication and moderate mechanical strength.
3003 aluminum sheet is known for its balanced combination of properties that make it a versatile material for many applications. Key characteristics include:
Good Corrosion Resistance: It resists oxidation and corrosion in most atmospheric environments, making it suitable for outdoor and marine use.
Moderate Strength: Though not heat-treatable, its strength can be enhanced through cold working, providing better durability than pure aluminum.
Excellent Formability: It can be easily bent, shaped, and drawn, which is ideal for manufacturing processes like rolling, stamping, and bending.
Good Weldability: It can be welded easily using common techniques without compromising structural integrity.
Non-Heat-Treatable Alloy: Strengthening is achieved by work hardening rather than heat treatment.
Good Thermal and Electrical Conductivity: Though not as high as pure aluminum, it still offers decent conductivity.
Wide Range of Surface Finishes: Available in mill finish, anodized, painted, or embossed surfaces, allowing flexibility in appearance and protection.
These characteristics make 3003 aluminum sheet suitable for architectural, transportation, appliance, and industrial uses where moderate strength and excellent corrosion resistance are required.
