3105 Painted Aluminum Sheet Features
a. Durability: Provides a Strong, Wear-Resistant Coating
The 3105 painted aluminum sheet features a durable coating that effectively resists external environmental factors, enhancing the sheet's wear resistance. This coating is typically made from high-quality polyester or fluorocarbon materials, ensuring a stable appearance under various climatic conditions and providing long-term protection. The coating not only increases surface hardness but also prevents oxidation and UV damage, extending its service life. Whether in high temperatures, humid, or harsh climates, the 3105 painted aluminum sheet maintains stable performance.
b. Flexibility: Enhances Sheet Flexibility, Making It Suitable for Various Forming and Manufacturing Processes
The 3105 painted aluminum sheet exhibits excellent flexibility, making it highly adaptable to different manufacturing processes. Unlike other coated aluminum sheets, the coating on 3105 does not affect the sheet's ductility and workability, allowing for easy bending, stamping, and stretching. Whether used in construction, automotive manufacturing, or the production of various light industrial products, this flexibility allows the 3105 painted aluminum sheet to meet a wide range of shape requirements, ensuring its suitability for different application scenarios.
c. Corrosion Resistance: Exceptional Corrosion Resistance that Extends the Sheet's Service Life
The 3105 painted aluminum sheet boasts outstanding corrosion resistance, making it particularly suitable for use in damp or salt-laden environments. The coating provides an extra layer of protection, effectively resisting acid rain, sea breeze, and other corrosive substances. Even in high humidity or marine environments, the 3105 coated aluminum sheet maintains its structural and aesthetic integrity. Its corrosion resistance makes it widely used in building facades, transportation vehicles, and other outdoor facilities, reducing the need for maintenance and replacement.
d. Formability: High Formability, Easy to Process into Different Shapes and Structures
The 3105 painted aluminum sheet has high formability, allowing it to be easily transformed into various shapes and structures through common processing methods such as stretching, bending, and punching. Its excellent forming characteristics ensure that the aluminum sheet does not suffer from excessive deformation or cracking during processing, making it ideal for creating complex shapes or specific designs. This makes the 3105 painted aluminum sheet versatile for use in construction, home appliances, automotive, and other industries, easily combining with other materials for composite applications.
e. Weldability: Suitable for Most Manufacturing Technologies; However, Welding or Flame Cutting is Not Recommended Without Proper Protection Due to the Coating
The 3105 painted aluminum sheet is generally suitable for most manufacturing techniques, such as cold stamping and laser cutting. However, due to the presence of its surface coating, welding or flame cutting may damage the coating, reducing adhesion or causing surface damage. Therefore, when welding or flame cutting, it is recommended to take appropriate protective measures, such as removing the coating or using protective welding processes, to prevent damage to the coating. Without proper protection, welding may lead to undesirable heat-affected zones, affecting the overall structure and performance of the aluminum sheet.
Ensure proper protection during welding or flame cutting to avoid damage to the coating.

3105 Painted Aluminum Sheet Material Properties
3105 Painted Aluminum Sheet Base Material Properties
- Corrosion Resistance: 3105 is an Al-Mn series alloy, with 0.3% copper added. A stable oxide film forms on the surface, providing excellent corrosion resistance in atmospheric and humid conditions.
- Electrical Conductivity: With 98% aluminum content, 3105 has an electrical conductivity of approximately 41%, making it suitable for applications requiring conductivity or electromagnetic shielding.
- Workability: High plasticity in the annealed state, supports stamping, bending, and other cold working, allowing for complex shapes.
- Strength: Medium strength, suitable for light structures and low-load components, such as interior frames and decorative parts.
- Formability: High flexibility, suitable for bending, rolling, and deep drawing, especially in the annealed (O temper) or half-hard states.
- Weldability: Compatible with all commercial welding technologies, but electric arc welding is recommended for best results.
3105 Painted Aluminum Sheet Coating Process
- Surface Treatment: Supports fluorocarbon, polyester, and other coating sprays, enhancing weather resistance and aesthetics, suitable for long-term outdoor use.
- Protective Performance: The coating effectively blocks corrosive agents, extending the lifespan of the base material, making it suitable for harsh environments like chemical equipment and coastal buildings.
Pre-coating (coil coating) is a continuous automated process where aluminum coils are cleaned, chemically pre-treated, primed, then coated on one or both sides and finally cured in a furnace. The coating system typically includes:
- Primer Layer: Ensures adhesion and corrosion resistance.
- Topcoat Layer: Polyester (PE) or fluoropolymer (PVDF), providing UV resistance, wear resistance, and color stability.
- Back Coat Layer: A thinner coating on the back for enhanced corrosion protection.
The total coating thickness ranges from 18 µm to 28 µm, with a chromate conversion layer (about 5 – 8 µm) under the primer to enhance adhesion.
3105 Painted Aluminum Sheet Surface Treatment and Color
3105 painted sheet material is available in standard colors such as white, black, red, blue, yellow, and herringbone patterns, and offers custom RAL and special surface treatments. The painted surface is semi-gloss to smooth, with pencil hardness typically greater than 2H, good flexibility, and can be bent 1T/2T without cracking. Gloss level ranges from matte (10%) to high gloss (90%) according to the EN ISO-2813 standard.
3105 Painted Aluminum Sheet Physical and Mechanical Properties
In common H12 or H14 temper, the minimum tensile strength of 3105 painted sheets is 19ksi, yield strength is 15ksi, and elongation is between 1% and 3%, depending on thickness. The alloy density is approximately 2.70 g/cm³, with excellent conductivity (over 30% IACS) and weldability similar to pure aluminum. As a non-heat treatable alloy, its strength is obtained through cold working rather than solid solution treatment.
3105 Painted Aluminum Sheet Processing Performance and Formability
The painted sheet retains the high formability of the base alloy, suitable for bending, stamping, rolling, and deep drawing. It can be welded (with appropriate surface protection) and also cut by shearing, laser, or plasma cutting. However, when machining, it is recommended to use oil-based lubricants to avoid damaging the surface. The minimum bend radius depends on the temper and coating thickness, but generally allows for sharp bends in architectural profiles and complex shapes.
