Product Description

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 Manufactured by high-precision slitting equipment, the thickness tolerance is controlled within ±0.02mm and width tolerance within ±0.1mm, ensuring consistency in batch processing.
  • Excellent Processability It can be easily subjected to bending, stamping, welding, and surface treatment (anodizing, powder coating), adapting to diverse manufacturing needs.
  • Lightweight & High Strength With a density of 2.7g/cm³, it is lighter than steel while providing sufficient strength (especially heat-treatable 6000 series), reducing product weight.
  • Strong Corrosion Resistance The natural oxide film on the surface and alloying elements (magnesium, manganese) enhance corrosion resistance, suitable for indoor and outdoor applications.
  • Cost-Effective The slitting process has high material utilization rate, and the stable performance reduces post-processing costs, making it ideal for mass production.
Major Application Fields
  • Electronics Industry Used as heat sink strips for LED lights, conductor strips for transformers, and battery connecting strips, leveraging its good thermal and electrical conductivity.
  • Construction Industry Applied in architectural decorative strips, door and window frames, and ceiling edge strips, benefiting from its corrosion resistance and aesthetic appeal after surface treatment.
  • Automotive Industry Utilized for automotive trim strips, heat shield strips, and structural reinforcement strips, contributing to vehicle lightweighting and corrosion resistance.
  • Packaging Industry Used as can body strips, bottle cap sealing strips, and packaging box edge strips, due to its formability and food safety (for food packaging).
  • Industrial Hardware Manufactured into fastener strips, spring strips, and tool parts, relying on its balanced strength and ductility.
Quality Control & Storage
  • Quality Indicators Dimensional accuracy (tested by calipers and width gauges), surface quality (no scratches, burrs, or oxidation), and mechanical properties (batch sampling for tensile and elongation tests).
  • Storage Guidelines Store in a dry, well-ventilated warehouse to prevent oxidation; place on flat supports to avoid bending; separate different alloys and tempers to prevent confusion; cover with dustproof cloth to avoid contamination.

Frequently Asked Questions (FAQ)
Q
What is the difference between 1000 series and 6000 series aluminum strips?
The 1000 series (pure aluminum) offers high electrical conductivity and excellent corrosion resistance but lower strength, making it ideal for heat sinks and electrical conductors. The 6000 series (Al-Mg-Si alloy) is heat-treatable and provides significantly higher strength after aging treatment, making it suitable for automotive structural parts and architectural profiles where both strength and corrosion resistance are required.
Q
What thickness and width tolerances can be achieved for aluminum strips?
Aluminum strips manufactured with high-precision slitting equipment achieve a thickness tolerance of ±0.02mm and a width tolerance of ±0.1mm. These tight tolerances ensure dimensional consistency across large production batches, which is critical for automated assembly and precision manufacturing processes.
Q
Which aluminum strip alloy is best suited for marine or outdoor environments?
The 5000 series (Al-Mg alloy), particularly 5052, is best suited for marine and outdoor environments. Its magnesium content (1.0% – 5.0%) provides excellent corrosion resistance against saltwater and moisture. It is widely used in marine components, structural brackets, and pressure vessel parts where long-term environmental exposure is expected.
Q
What surface treatments can be applied to aluminum strips?
Aluminum strips support a wide range of surface treatments including anodizing, powder coating, painting, and brushing. Anodizing enhances corrosion resistance and surface hardness while providing an attractive finish. Powder coating offers additional color options and durability. These treatments make aluminum strips suitable for architectural, decorative, and industrial applications.
Q
How should aluminum strips be stored to prevent quality degradation?
Aluminum strips should be stored in a dry, well-ventilated warehouse away from moisture and corrosive substances to prevent oxidation. They should be placed on flat supports to avoid bending or deformation. Different alloy series and tempers must be stored separately and clearly labeled to prevent mixing. Covering with dustproof cloth or packaging material helps protect the surface from contamination and scratches.
Q
What processing temper should I choose for complex stamping and forming operations?
For complex stamping, bending, and forming operations, the O State (Annealed) temper is recommended. Annealed aluminum strips have the highest ductility and the lowest hardness, allowing them to be formed into intricate shapes without cracking. If moderate strength is also needed alongside formability, the H14 (Semi-Hard) temper provides a balanced combination suitable for general structural parts and packaging applications.
