Aluminium sheet AA3105 H14 with PVC

Product Details

What Is AA3105 H14 Aluminium Sheet?

AA3105 is an aluminum-manganese alloy, with manganese as the primary alloying element, designed to deliver enhanced corrosion resistance and ductility compared to pure aluminum grades. The H14 temper designation refers to a strain-hardened (work-hardened) condition, achieving a balanced state of softness and rigidity—easy to form yet structurally stable, with no additional heat treatment required.

This alloy complies with international standards including ASTM B209, EN 485, and GB/T 3880, making it a universal choice for indoor and outdoor applications that demand long-term durability and consistent performance.

What Is AA3105 H14 Aluminium Sheet with PVC Coating?

AA3105 H14 aluminium sheet with PVC features a removable, transparent protective polyvinyl chloride film laminated to one or both surfaces of the bare sheet during production. The PVC coating acts as a temporary protective barrier, safeguarding the sheet’s surface from scratches, scuffs, dust, moisture, and mechanical damage during transportation, storage, handling, and processing.

The PVC film is easy to peel off after installation, fabrication, or surface finishing, leaving the underlying aluminum sheet with a pristine, unblemished finish.

Core Differences: Bare AA3105 H14 vs. PVC-Coated AA3105 H14

Comparison Item	Bare AA3105 H14 Aluminium Sheet	AA3105 H14 Aluminium Sheet with PVC
Surface Protection	No protective layer; surface vulnerable to scratches, stains, and handling damage	Temporary PVC barrier; full surface protection against damage and contamination
Surface Finish	Natural mill finish or customizable (anodized, painted, polished)	Retains original mill finish perfectly; zero surface defects post-peeling
Cost	Lower upfront cost, no additional coating expense	Slightly higher cost due to PVC lamination, but reduces rework and waste
Handling & Transport	Requires careful packaging to avoid damage; high risk of surface flaws	Durable protection; safe for rough handling and long-distance shipping
Processing Suitability	Ideal for structural, non-visible components; acceptable for low-surface-requirement parts	Perfect for visible panels, decorative parts, and precision fabrication where flawless finish is mandatory
Post-Processing	Ready for direct cutting, bending, welding, or finishing	Peel off PVC before welding, painting, or anodizing; no residue left on surface

Key Properties of AA3105 H14 Aluminium Sheet (Both Variants)

1. Corrosion Resistance

Outstanding natural corrosion resistance, far superior to 1XXX pure aluminum grades. Performs reliably in humid, coastal, and mildly corrosive environments, ideal for outdoor and marine auxiliary applications.

2. Formability & Workability

Excellent ductility under H14 temper; easy to bend, fold, stamp, roll, and deep-draw without cracking. Supports complex fabrication processes for various component shapes.

3. Weldability

Exceptional welding performance via MIG, TIG, and resistance welding. Welded joints maintain high integrity and corrosion resistance, with minimal risk of defects.

4. Strength & Durability

Moderate mechanical strength, lightweight structure, and long service life. Resists deformation under daily load-bearing conditions, suitable for long-term use.

5. Surface Treatability

Compatible with a wide range of finishing processes: anodizing, powder coating, painting, and polishing. Adheres well to coatings for enhanced aesthetics and protection.

How to Choose: Bare or PVC-Coated AA3105 H14?

Choose Bare AA3105 H14 If:

Your project involves non-visible, structural components where surface appearance is not a priority.
You need to minimize upfront material costs and have strict budget constraints.
The sheet will undergo immediate welding, coating, or secondary finishing that obscures the base surface.
Handling and storage conditions are controlled, with low risk of surface damage.

Choose AA3105 H14 with PVC If:

The sheet is for visible, decorative, or high-end applications that demand a perfect, scratch-free surface.
You need to transport the material long distances or store it for extended periods.
Fabrication involves multiple handling steps that could damage unprotected surfaces.
You want to reduce rework costs caused by surface defects and ensure a high-quality finished product.

Quality & Standard Compliance

Our AA3105 H14 aluminium sheet (both bare and PVC-coated) meets strict international standards:

ASTM B209 (standard specification for aluminium alloy sheet and plate)
EN 485 (aluminium and aluminium alloys sheet for general engineering)
GB/T 3880 (Chinese national standard for aluminium alloy sheets)
PVC film meets food-grade and environmental protection requirements, residue-free after peeling

Conclusion

AA3105 H14 aluminium sheet is a versatile, cost-effective solution for diverse industrial and architectural needs. The choice between bare and PVC-coated variants boils down to surface finish requirements, handling conditions, and project quality standards.

Opt for bare sheet for cost-sensitive, non-visible applications, and select the PVC-coated version for visible, high-quality projects that require flawless surface protection.
