Cold-rolled patterned aluminum alloy
Cold-rolled patterned aluminum alloy
Product Overview
Cold-rolled patterned aluminum alloy is an aluminum material with periodic patterns embossed on the surface through cold rolling.
Product Details
1. Material Definition and Process Principles
Cold-rolled patterned aluminum alloy is produced byCold rolling processAluminum alloy with periodic patterns embossed on the surface. The core process involves cold rolling aluminum alloy substrates (such as 1060, 3003, 5005 alloys), forming raised and recessed patterns via die rolling, followed by annealing and surface treatments (e.g., anodizing, powder coating). Pattern types include diamond, stripe, wave, and grid textures, typically with a depth of0.1–1.5mmWidth and spacing are customized per requirement.
2. Core Production Process
Cold-rolled forming (1)
Temperature ControlRolling temperature is below the recrystallization temperature (approximately 250–400°C), and the pattern is formed through multi-pass rolling with a reduction of 5–30%.
Mold Design: Uses high-precision patterned rolls to ensure consistent pattern dimensions (tolerance ±0.05mm).
AnnealingLow-temperature annealing (150–200°C) after rolling to relieve work hardening and restore material ductility.
Surface treatment (2)(Optional Process)
AnodizingGenerates a dense oxide layer (thickness 3–15μm) to enhance corrosion resistance and appearance.
Spray Decoration: Apply spray polyurethane, fluorocarbon coatings, etc., to enhance color options and weather resistance.
Electroplating Process: Plate with metals such as copper or nickel to achieve conductivity or a special texture.

4. Pattern Types and Machining Advantages
Pattern Type | Features | Typical Use Cases |
|---|---|---|
Diamond pattern | Most common pattern: regular arrangement for enhanced 3D visual effect. | Building curtain walls, elevator interiors, and furniture panels |
stripes | Parallel lines, minimalist style. Customizable spacing and angle. | Automotive interior trim, home appliance panels, and packaging boxes |
Wavy pattern | Continuous wavy texture for a soft, non-slip feel | Floor decking, sports equipment, and ship decks |
grid pattern | Precision grid mesh with high-density texture for enhanced durability | Industrial Equipment Guards and Tool Handles |
Processing Advantages：
No plating required: Natural matte surface reduces maintenance costs.
Composite Process: Combines with anodizing and powder coating for integrated multi-functionality (e.g., antimicrobial coatings).
Lightweight: Compared with pattern-embossing dies, the cold rolling process achieves a material utilization rate of over 95%.
