There are several main types of aluminum profiles

1. Classification by material
Pure aluminum profile
Main ingredients: Aluminum content is as high as 99% or more.
Features: Soft texture and good ductility, but relatively low strength.
Application: Mainly used in occasions with low requirements for strength, such as decorative components.
Alloy aluminum profiles
Main composition: Aluminum is an alloy with other metal elements (such as copper, magnesium, zinc, silicon, etc.).
Features: According to the different alloying elements, it has different strength, hardness, corrosion resistance and other characteristics.
Application: Widely used in construction, aerospace, transportation, machinery manufacturing and other fields.

2. Classification by structure
Solid aluminium profiles
Features: The cross-section is solid, with high strength and stiffness.
Application: It is used in occasions that need to bear large loads, such as building components, mechanical equipment frames, etc.
Hollow aluminium profiles
Features: The cross-section is hollow, the weight is light, and it has good heat and sound insulation performance.
Application: Used in doors and windows, curtain walls, pipes and other occasions.
Semi-hollow aluminium profiles
Features: The cross-section is partially solid and partially hollow, which combines the advantages of solid aluminum profile and hollow aluminum profile.
Application: Used in places that require certain strength and lightweight requirements, such as automobile bodies, aerospace vehicles, etc.

3. Classification by use
Architectural aluminium profiles
It is mainly used for building doors and windows, curtain walls, railings, etc.
Features: Good corrosion resistance, fire performance and aesthetics.
Industrial aluminium profiles
It is mainly used for mechanical equipment, automation equipment, assembly lines, etc.
Features: It has high strength and rigidity, easy to process and assemble.
Decorative aluminium profiles
Mainly used for interior decoration, furniture, lamps, etc.
Features: It has rich colors and textures, and has a good decorative effect.
Special aluminium profiles
Such as aerospace aluminum profiles, high-speed train aluminum profiles, etc.
Features: Extremely high strength and lightweighting requirements, often requiring custom production for specific needs.
