Core Properties of 3003 & 3105 H24 1mm Thick Painted White Aluminum Coils
3003 and 3105 aluminum alloys in H24 temper, combined with 1mm thickness and white painted coating, offer a unique set of properties tailored to practical industrial and commercial needs. While sharing foundational advantages, each alloy has distinct characteristics to suit specific applications. Here are their key properties, amplified by the H24 temper and white paint coating:
1. 3003 H24 1mm Thick Painted White Aluminum Coil
Balanced Strength & Formability (H24 Temper Advantage): The H24 temper (partially cold-worked and stabilized) gives 3003 excellent tensile strength (140-160 MPa) and yield strength (110-130 MPa), while retaining good formability. The 1mm thickness enhances rigidity without compromising the ability to bend, stamp, or roll into custom shapes-ideal for applications requiring both structural stability and design flexibility.
Superior Corrosion Resistance with White Coating: 3003 naturally resists atmospheric corrosion, fresh water, and mild industrial pollutants. The high-quality white paint coating (available in polyester or PVDF) adds a robust barrier against moisture, UV radiation, and chemical exposure, making it suitable for indoor and outdoor applications in temperate and humid climates.
Clean Aesthetics & Versatile White Finish: The bright white paint finish delivers a clean, modern look that complements various architectural and product designs. It provides excellent color retention (resists fading under UV light) and is easy to clean-perfect for applications where appearance and hygiene are critical, such as healthcare facilities or food processing areas.
Cost-Effective & Lightweight: 3003 is an economical 3xxx series alloy, and the 1mm thickness balances performance with material efficiency. With a density of 2.73 g/cm³, it's lightweight, reducing transportation and installation costs compared to heavier materials like steel.
2. 3105 H24 1mm Thick Painted White Aluminum Coil
Enhanced Strength & Durability (H24 Temper): 3105 in H24 temper offers higher tensile strength (150-170 MPa) and yield strength (120-140 MPa) than 3003, thanks to its optimized alloy composition. The 1mm thickness further boosts structural stability, making it suitable for applications requiring greater load-bearing capacity, such as architectural panels and heavy-duty HVAC components.
Excellent Corrosion Resistance for Harsh Environments: 3105 exhibits superior corrosion resistance compared to 3003, particularly against salt spray and industrial fumes. When combined with the white paint coating, it provides exceptional protection in coastal areas, industrial zones, and other aggressive environments-ensuring long-term durability with minimal maintenance.
Consistent White Coating Performance: The white paint adheres exceptionally well to 3105's smooth surface, delivering a uniform finish with no visible defects. The coating's resistance to chipping, scratching, and fading ensures the coil retains its clean, professional appearance even in high-traffic or harsh conditions.
Excellent Weldability & Joinability: 3105 maintains good weldability using standard MIG/TIG welding techniques, and the 1mm thickness allows for easy joining with other materials. This makes it ideal for assembled components where structural integrity and aesthetic consistency (white finish) are both critical.
3. Advantages of H24 Temper & 1mm Thickness
H24 Temper Benefits: The partially hardened H24 temper strikes a perfect balance between strength and ductility. Unlike fully hardened tempers (e.g., H18), it retains enough formability for bending and stamping, while offering higher strength than annealed (O) temper-ideal for 1mm thick coils that need to support loads without deformation.
1mm Thickness Advantages: The 1mm thickness is a versatile choice for many applications: thin enough for easy processing (cutting, forming) yet thick enough to provide reliable rigidity. It's lightweight but robust, reducing material waste and transportation costs while ensuring long-term structural stability.
4. Advantages of White Painted Coating
Aesthetic Versatility: White is a timeless, neutral color that complements any design style-from modern architecture to consumer goods. It brightens spaces and creates a clean, professional look that appeals to both commercial and residential clients.
UV & Weather Resistance: Our white paint (polyester or PVDF) is formulated to resist UV fading, chalking, and peeling, ensuring the finish retains its color and integrity even after years of outdoor exposure.
Easy Maintenance: The smooth painted surface is resistant to dirt, stains, and mold. It can be easily cleaned with mild detergent and water, reducing maintenance costs and ensuring a consistently clean appearance.
Additional Corrosion Protection: The paint acts as a barrier between the aluminum substrate and the environment, preventing oxidation and corrosion. This extends the lifespan of the coil, especially in harsh or humid conditions.

Processing & Fabrication Tips for 3003 & 3105 H24 1mm Thick Painted White Aluminum Coil
To maximize the performance and aesthetic quality of your end products, here are practical processing tips tailored to 3003 and 3105 H24 1mm thick painted white aluminum coils:
1. Coil Handling & Storage
Handle coils with soft slings or coil hooks to avoid edge damage and surface scratches-critical for the painted finish, as even minor scratches are visible. Avoid touching the painted surface with bare hands to prevent oil transfer and staining.
Store coils in a dry, clean, covered warehouse away from moisture, dust, and corrosive substances. Keep coils vertically on dedicated racks to prevent deformation. Avoid direct sunlight to prevent premature fading of the white paint.
If storing for extended periods (over 3 months), wrap the coils in moisture-resistant film to protect the painted surface from dust and humidity. Retain the original packaging until fabrication to minimize contamination.
2. Cutting & Slitting
Use precision slitting equipment with sharp, carbide-tipped blades to ensure clean, burr-free edges. Ensure the slitting equipment is clean and free of debris to avoid scratching the painted surface.
Adjust slitting speed and pressure to match the 1mm thickness-avoid excessive pressure that could damage the paint coating. For post-cutting processing, deburr edges gently to prevent paint chipping during forming.
3. Forming & Bending
Both 3003 and 3105 in H24 temper offer good formability. For 1mm thick coils, use moderate forming pressure for bending, stamping, and roll forming. Follow the recommended minimum bend radius (3x material thickness) to avoid cracking or peeling the paint coating.
Avoid overworking the material during forming-H24 temper has limited ductility compared to annealed temper. For complex shapes, consider pre-heating the coil to 80-120°C to improve formability and reduce paint damage.
4. Welding & Joining
Welding: Use MIG/TIG welding with matching filler metals (ER3003 for 3003 alloy, ER3105 for 3105 alloy). Before welding, remove the paint coating from the weld area (using grinding or chemical stripping) to ensure proper weld penetration. After welding, touch up the weld area with matching white paint to maintain corrosion resistance and aesthetic consistency.
Mechanical Joining: For non-welded joints, use rivets, screws, or adhesives compatible with aluminum and painted surfaces. Ensure fasteners are made of aluminum or stainless steel to avoid galvanic corrosion. Pre-drill holes carefully to prevent paint chipping around the hole edges.
5. Surface Maintenance
Clean the painted surface regularly with a soft cloth and mild detergent (avoid abrasive cleaners or tools) to remove dust, stains, and fingerprints. For stubborn stains, use a non-abrasive aluminum cleaner specifically formulated for painted surfaces.
Avoid exposure to harsh chemicals (acids, alkalis) that can damage the paint coating. If accidental exposure occurs, rinse the surface immediately with clean water and dry thoroughly.
