Typical characteristics

Lightweight and High-Strength

With a density of 2.7 g/cm³, it weighs one-third that of steel. High strength is achieved through alloying.

High Corrosion Resistance

The naturally formed dense oxide film on the surface provides excellent resistance to atmospheric and chemical corrosion, and anodizing further enhances durability.

Easy Processing and Versatility

It offers excellent processing properties for extrusion, cutting, and forging, making it easy to form a variety of complex parts and amenable to a variety of surface treatments.

Thermal and Electrical Conductivity

It is an excellent conductor of heat and electricity, widely used in heat sinks and conductive components. Its weight conductivity surpasses that of copper.

Environmentally Friendly and No Low-Temperature Brittleness

It is 100% recyclable, with extremely low energy consumption for recycling. Performance improves in low-temperature environments without sacrificing performance, eliminating the risk of brittleness.

Applications

Structural Parts/Components/Parts Applications

Aluminum bars are used in aerospace applications for aircraft frames, engine components, and landing gear linkages. In industrial automation, aluminum flat bars are processed into robotic arms, joints, and precision instrument brackets, effectively improving movement efficiency. This is due to their strength-to-weight ratio and machinability.

Chassis/Radiator/Conductive Component Applications

In the transportation sector, aluminum bar is used to manufacture automotive chassis suspension components, control arms, and steering knuckles. Its thermal conductivity makes it an ideal heat sink material for CPU heat sinks, LED light bases, and power supply heat sinks. Highly conductive aluminum flat bars are also processed into components such as busbars and terminal blocks for electrical cabinets.

Building/Door/Window/Home Applications

In buildings, aluminum bar serves as load-bearing structures, such as curtain wall keels and sunroom frames. It is the core profile of doors and windows, providing structural support and ensuring sealing. In the home, aluminum bar is used to make furniture brackets, lighting structures, and decorative moldings, leveraging their weather resistance and diverse design options.

Common types

1. Classification by Alloy Series

Internationally, international grades (such as AA 6061) or Chinese grades (such as 6061) are commonly used. They are primarily categorized as follows:

(1) 1xxx Series: Pure aluminum rods, offering excellent conductivity, corrosion resistance, and workability, but lower strength. Typical grade: 1060, 1070.

(2) 2xxx Series: Aluminum-copper alloys, offering high hardness and strength, classified as aviation-grade duralumin, but with poor corrosion resistance. Typical grades: 2011, 2017, 2024.

(3) 6xxx Series: Aluminum-magnesium-silicon alloys, the most commonly used series. They offer excellent overall performance, with medium strength, good corrosion resistance, weldability, and ease of processing. Typical grades: 6061, 6063, 6082.

(4) 7xxx Series: Aluminum-zinc-magnesium alloys, ultra-high-strength alloys, typically used in applications requiring high strength, but with slightly lower stress corrosion resistance. Typical grade: 7075.

 

2. Classification by Shape

(1) Round Aluminum Bar: The most common type, used for manufacturing shafts, sleeves, bolts, etc.

(2) Square Aluminum Bar: Square cross-section.

(3) Hexagonal Aluminum Bar: Regular hexagonal cross-section, commonly used for manufacturing nuts, wrenches, etc.

(4) Flat Aluminum Bar: Rectangular cross-section, commonly used for framing, trim, and structural support.

 

3. Classification by Production Process and Bar Type

(1) Extruded Bar: Hot extrusion is used to form the bar, the most common manufacturing process.

(2) Rolled Bar: Rolled using a rolling mill.

(3) Temper:

• O Temper: Annealed. Annealing results in the material reaching its softest state, offering excellent workability and ease of bending and forming, but with the lowest strength.
• T4 Temper: Solution treated, naturally hardens at room temperature. Offers good formability and moderate strength.
• T5 Temper: Cooled from the high extrusion temperature and then artificially aged. Strength is higher than T4 Temper, with good dimensional stability and a reasonable surface quality.
• T6 Temper: Solution treated and fully artificially aged, achieving the highest strength. This is the most widely used and offers excellent overall performance.
• T651 Temper: Based on the T6 Temper, tensile stress relief treatment is applied to effectively reduce post-processing deformation, making it suitable for high-precision and precision machining.

Production Process

Alloy smelting and casting → Homogenization → Extrusion or hot rolling → Heat treatment → Finishing and testing → Finished aluminum bars

 

Melting and casting

Aluminum ingots are melted and mixed with alloying elements, then cast into cylindrical ingots.

Hot working & forming

The extrusion process is primarily used, where pressure is applied to a die to directly achieve the desired cross-sectional shape. Rolling is also used as a supplementary process.

Heat treatment & strengthening

Solution treatment and aging treatments significantly improve the strength, hardness, and other mechanical properties of the aluminum bars.

Finishing & testing

Fine processing, such as straightening, cutting, and surface treatment, is performed, and rigorous quality assurance is ensured.
