China's leading 6063 Aluminum Rod factory primarily supplies rods with diameters ranging from φ5mm to 200mm, with limited stock of larger diameter rods. Standard length is 6 meters, but custom lengths and cut-to-size options are available. Dimensional tolerances are flexible, suitable for extrusion molding requirements.
6063 aluminum rods belong to the 6000 series aluminum-magnesium-silicon alloy, a heat-treatable wrought aluminum alloy. It is one of the most widely used aluminum materials in construction, decoration, and light structural applications, often referred to in the industry as a construction-specific aluminum alloy. The mainstream is the T5 temper (air-cooled aging after extrusion, offering the best cost-performance ratio and highest production volume), followed by the T6 temper (slightly stronger than T5). H112 and O tempers are also commonly available. There are no complex stress-relieving tempers.
What is the difference between 6063 and 6061 aluminum rods?
Comparison Dimensions
6063 Aluminum Rod
6061 Aluminum Rod
Product Positioning
Architectural decoration, light extrusion alloy
General-purpose structural and machining-specific alloy
Alloy Composition
Low magnesium and silicon content, few strengthening elements
Higher magnesium and silicon content, more balanced strengthening element ratio
Overall Strength
Low content, unable to withstand large loads
Medium to high content, stronger mechanical properties
Extrusion/Forming Performance
Excellent plasticity, easy to extrude and bend, suitable for complex cross-sections
Moderate plasticity, slightly more difficult to extrude, not suitable for large deformations
Machining Performance
Soft material, prone to tool sticking during cutting, average surface finish
Excellent machinability, less prone to tool sticking, suitable for precision machining
Surface Treatment Effect
Top-notch anodizing, electrophoresis, and spraying effects, uniform and bright color, strong decorative properties
Surface treatment is possible, but the anodized color is darker, and the decorative texture is weaker
Common Supply Status
Mainly T5, some T6
Main grades: T6, T4, T651, wider range of working conditions
Corrosion Resistance
Good, slightly better than 6061, suitable for general outdoor use
Good performance, suitable for general outdoor and humid environments
Applicable Load Capacity
Only for light loads, low stress, and non-load-bearing parts
Medium load, structural load-bearing components
Mainstream Specifications
Mainly small diameter rods and various extruded profiles
Full range of round and square bars available, ample stock of large-diameter bars
Market Price
Slightly lower price for the same specifications
Slightly higher price for the same specifications
Aluminum rod manufacturers recommend: For aesthetics, extrusion, and light loads → choose 6063; for strength, machining, and load-bearing capacity → choose 6061.
