China Aluminium Strip Suppliers - High-Quality Factory Direct Aluminum Band for Electronics, Construction, and Automotive
Classification by Alloy Series
Aluminum Strip is classified based on alloy series, processing temper, and application scenarios, each with distinct characteristics to meet specific usage requirements. The key classifications are summarized in the table below:
| Classification Criterion | Category | Key Features | Typical Applications |
| Alloy Series | 1000 Series (Pure Aluminum Strip) | Aluminum ≥99.0%, high conductivity, good corrosion resistance | Heat sinks, electrical conductors, food packaging edges |
| 3000 Series (Al-Mn Alloy Strip) | Manganese 1.0%-1.5%, balanced strength and formability | Cookware edges, decorative strips, automotive trim | |
| 5000 Series (Al-Mg Alloy Strip) | Magnesium 1.0%-5.0%, high strength, excellent corrosion resistance | Marine components, structural brackets, pressure vessel parts | |
| 6000 Series (Al-Mg-Si Alloy Strip) | Heat-treatable, high strength after aging | Automotive structural parts, architectural profiles, hardware | |
| Processing Temper | O State (Annealed) | High ductility, easy to bend and stamp | Complex forming parts, decorative components |
| H14 State (Semi-Hard) | Moderate strength and ductility | General structural parts, packaging clips | |
| T6 State (Heat-Treated) | High strength, good rigidity | Automotive load-bearing parts, industrial brackets |
Key Specifications & Mechanical Properties
Aluminum Strip has strict dimensional control to ensure processing accuracy, and its mechanical properties vary with alloy and temper. Typical specifications and performance data are shown below:
| Alloy & Temper | Thickness Range (mm) | Width Range (mm) | Tensile Strength (MPa) | Elongation (%) |
| 1060-O | 0.1-6.0 | 5-200 | 75-105 | ≥25 |
| 3003-H14 | 0.2-8.0 | 10-300 | 130-180 | ≥5 |
| 5052-H32 | 0.3-10.0 | 15-400 | 170-210 | ≥10 |
| 6061-T6 | 0.5-12.0 | 20-500 | 310-380 | ≥8 |
Core Advantages
Precise Dimensions
Thickness tolerance within ±0.02mm and width tolerance within ±0.1mm, ensuring consistency.
Excellent Processability
Easily subjected to bending, stamping, welding, and various surface treatments.
Lightweight & High Strength
Density of 2.7g/cm³, lighter than steel while providing sufficient structural rigidity.
Strong Corrosion Resistance
Natural oxide film and alloying elements enhance durability in indoor and outdoor environments.
Cost-Effective
High material utilization rate and stable performance reduce total post-processing costs.
Major Application Fields
- Electronics Industry: Heat sink strips for LED lights, conductor strips for transformers, and battery connecting strips.
- Construction Industry: Architectural decorative strips, door and window frames, and ceiling edge strips.
- Automotive Industry: Trim strips, heat shield strips, and structural reinforcement strips for vehicle lightweighting.
- Packaging Industry: Can body strips, bottle cap sealing strips, and packaging box edge strips (Food Safe).
- Industrial Hardware: Fastener strips, spring strips, and tool parts.
Quality Control & Storage
Quality Indicators: Dimensional accuracy (tested by calipers and width gauges), surface quality (no scratches, burrs, or oxidation), and mechanical properties (tensile and elongation tests).
Storage Guidelines: Store in a dry, well-ventilated warehouse; place on flat supports to avoid bending; separate different alloys/tempers; cover with dustproof cloth.
