1. Transportation and Automotive

Trucks, Trailers, and Railway Vehicles: Used for structural components like chassis, frames, and containers due to their balance of strength, weldability, and corrosion resistance.

Ships and Marine Applications: Employed in shipbuilding for decks, railings, and lightweight structural parts.

Electric Vehicles (EVs): Ideal for battery enclosures and thermal management systems, leveraging their thermal conductivity and formability.

2. Construction and Architecture

Tower Building and Structural Frameworks: Extensively used in construction for towers, bridges, and modular building systems, offering flexibility and durability.

Industrial Workstations and Assembly Lines: Fabricated into workbenches, conveyor systems, and equipment frames due to their machinability and load-bearing capacity.

3. Machinery and Industrial Equipment

Machine Guards and Covers: Utilized for protective casings in machinery, benefiting from their corrosion resistance and ease of shaping.

Extrusion-Based Systems: Paired with specialized hardware (e.g., MISUMI’s insertion nuts and stoppers) for modular assembly in industrial automation.

4. Consumer Goods and Furniture

Furniture and Cabinetry: Used in high-end furniture, cabinets, and shelving due to its aesthetic finish and structural integrity.

Electronics and Heat Exchangers: Applied in electronic enclosures and heat sinks for efficient thermal management.

5. Aerospace and Defense

Aircraft Components: While less common than 2xxx or 7xxx series, 6xxx alloys are used in non-critical aircraft parts requiring moderate strength and corrosion resistance.

Key Properties Driving These Uses

Strength and Formability: Balances tensile strength (180–360 MPa) with excellent extrusion capabilities.

Corrosion Resistance: Enhanced by natural oxidation, suitable for outdoor and marine environments.

Weldability and Machinability: Facilitates complex fabrication processes without compromising structural integrity.

With the characteristics of medium strength, corrosion resistance and easy processing, 6-series aluminum has become the preferred material for industrial and civil fields. In the future, there is still wide application potential in new energy (such as battery components), environmental protection equipment (such as sewage treatment structures) and other fields.
