ASTM B221 Grade 6063-T5 Aluminum Alloy Tube Overview
GNEE supplies ASTM B221 Grade 6063-T5 aluminum alloy round tubes, ASTM B221 Grade 6063-T6 aluminum round tubes, and custom aluminum profile tubes designed specifically for pneumatic cylinders and pneumatic equipment applications.
6063 aluminum alloy is widely recognized for its excellent extrusion performance, smooth surface finish, and outstanding corrosion resistance. Among its tempers, 6063-T5 aluminum is one of the most commonly used options for pneumatic cylinder tubes due to its balanced mechanical properties and superior anodizing performance.
ASTM B221 6063-T5 Aluminum Tube for Pneumatic Equipment Applications
The ASTM B221 6063-T5 aluminum alloy round tube offered by GNEE is manufactured using high-quality extrusion processes. After anodizing, the tube surface becomes smooth, dense, and visually appealing, eliminating the need for secondary painting or coating.
Key advantages include
Lightweight structure with high dimensional stability
Excellent resistance to corrosion and oxidation
Smooth anodized surface suitable for sealing systems
Ideal for pneumatic cylinders, portable devices, and air-pressure equipment
6063-T5 aluminum refers to 6063 alloy artificially aged after extrusion without solution heat treatment, making it especially suitable for precision pneumatic components.
Anodized 6063-T5 Aluminum Pneumatic Cylinder Tube Performance
ASTM B221 6063-T5 Anodized Aluminum Tube Benefits

ASTM B221 AA6063 Chemical Composition (Typical Limits)
| Element | Si | Fe | Cu | Mn | Mg | Cr | Zn | Ti | Others (each) | Others (total) | Al |
|---|---|---|---|---|---|---|---|---|---|---|---|
| AA6063 | 0.20–0.60 | ≤0.35 | ≤0.10 | ≤0.10 | 0.45–0.90 | ≤0.10 | ≤0.10 | ≤0.05 | ≤0.05 | ≤0.15 | Balance |
The optimized magnesium and silicon content allows 6063 alloy to form a stable Mg₂Si strengthening phase, providing good mechanical performance while maintaining excellent extrudability.

Which Is Stronger: 6063 or 6061 Aluminum?
Both 6063 and 6061 aluminum alloys offer excellent formability, machinability, and heat-treatability. However, 6061 aluminum provides slightly higher strength than 6063, especially in the T6 temper.
Which Is More Cost-Effective: 6063 or 6061?
For extruded components, 6063 aluminum is generally more economical, particularly when used in solid or thin-wall profiles. Its superior extrusion characteristics reduce manufacturing costs, making it a cost-effective choice for high-volume production.
Is 6063 Aluminum Corrosion-Resistant?
Yes. 6063 aluminum alloy offers excellent corrosion resistance, especially when anodized. It is also easy to weld, braze, and fabricate while maintaining moderate tensile strength and good machinability.
6063-T5 vs 6061-T6 Aluminum Applications
6063-T5 aluminum is widely used in architectural and decorative applications due to its smooth surface, excellent anodizing response, and aesthetic appeal.
6061-T6 aluminum is preferred for structural and load-bearing applications where higher strength and durability are required.
Can 6063 Aluminum Be Forged?
6063 aluminum, alloyed with magnesium and silicon, has good mechanical properties and is suitable for forging and heat-treatment processes. Like 6061 aluminum, it supports the production of complex shapes with smooth surfaces, making it ideal for anodized and visible components.
For applications requiring higher mechanical strength, alloys such as 6061 or 6082 aluminum are more commonly selected.
