China Aluminum Profile Suppliers Factory - Customizable Extruded Shapes for Various Industries
Key Specifications (Table)
Aluminum profiles are categorized based on cross-sectional shape, processing method, alloy series, and application scenarios, which directly determine their performance and use cases. Detailed classifications are shown in the following table:
| Classification Criterion | Specific Types | Core Characteristics | Typical Applications |
|---|---|---|---|
| Cross-Section Shape | Solid Profiles (Rods, Bars, Flat Bars) | No hollow structure, high structural stability, uniform stress | Mechanical shafts, fasteners, machining blanks, decorative trims |
| Hollow Profiles (Tubes, Pipes) | Light weight, high strength-to-weight ratio, material-saving | Architectural handrails, heat exchangers, furniture frames, hydraulic pipelines | |
| Standard Shaped Profiles (Angle, Channel, T-Shape, U-Shape) | Standardized cross-sections, easy assembly, good load-bearing | Structural supports, frame connectors, shelf brackets, construction beams | |
| Custom Special-Shaped Profiles | Tailored cross-sections, integrated functions, high design flexibility | Automotive parts, curtain wall connectors, electronic enclosures, industrial equipment components | |
| Processing Method | Extruded Profiles | High production efficiency, diverse shapes (solid/hollow/special-shaped), cost-effective | Architectural frames, door/window profiles, consumer product shells |
| Drawn Profiles | High dimensional precision (tolerance ±0.01mm), smooth surface | Precision components, medical instruments, hydraulic tubes | |
| Rolled Profiles | Suitable for simple shapes, large batch production, uniform thickness | Flat bars, angle bars, wide plates for construction | |
| Alloy Series | 1xxx Series (Pure Aluminum) | High corrosion resistance, good conductivity/thermal conductivity, low strength | Heat sinks, decorative profiles, electrical conductors |
| 3xxx Series (Al-Mn Alloy) | Enhanced strength vs. pure aluminum, excellent weldability | Architectural handrails, food packaging frames, heat exchange profiles | |
| 5xxx Series (Al-Mg Alloy) | Superior corrosion resistance (marine-grade), good ductility | Marine structures, offshore pipelines, automotive body parts | |
| 6xxx Series (Al-Mg-Si Alloy) | Heat-treatable, high strength, excellent formability | Architectural frames, automotive components, structural supports | |
| 7xxx Series (Al-Zn-Mg-Cu Alloy) | Ultra-high strength, good fatigue resistance | Aerospace components, high-load structural parts, sports equipment | |
| Application Scenario | Architectural Profiles | Aesthetic appearance, corrosion resistance, easy installation | Door/window frames, curtain walls, handrails, ceiling grids |
| Industrial Profiles | High strength, good machinability, functional integration | Machinery frames, conveyor components, heat exchanger cores | |
| Transportation Profiles | Light weight, high strength, fatigue resistance | Automotive frames, railway interior trim, ship hull components, aerospace parts | |
| Consumer Product Profiles | Aesthetic design, formability, light weight | Furniture frames, sports equipment (bicycle frames), electronic device casings |

Frequently Asked Questions
How are aluminum profiles classified?
Aluminum profiles are primarily classified based on four criteria: cross-sectional shape (solid, hollow, standard, custom), processing method (extruded, drawn, rolled), alloy series (1xxx to 7xxx series), and application scenarios (architectural, industrial, transportation, consumer products).
Which aluminum alloy series is best for marine applications?
The 5xxx Series (Al-Mg Alloy) is best suited for marine applications. It offers superior corrosion resistance (marine-grade) and good ductility, making it ideal for marine structures and offshore pipelines.
What is the difference between extruded and drawn aluminum profiles?
Extruded profiles are highly cost-effective and efficient for producing diverse shapes. Drawn profiles, on the other hand, offer much higher dimensional precision (with tolerances down to ±0.01mm) and a smoother surface finish, making them suitable for precision components and medical instruments.
Why is the 6xxx series alloy commonly used in architectural frames?
The 6xxx Series (Al-Mg-Si Alloy) is heat-treatable, provides high strength, and exhibits excellent formability. These characteristics make it the standard choice for architectural frames, automotive components, and structural supports.
When should 7xxx series aluminum profiles be used?
7xxx Series (Al-Zn-Mg-Cu Alloy) profiles should be used when ultra-high strength and good fatigue resistance are required. They are typically applied in aerospace components, high-load structural parts, and heavy-duty sports equipment.
