Aluminium Profile
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 |
