Dimensions of aluminum tubes and round hollow profiles are traditionally measured by their Outer Diameter (OD). Both small and medium diameters are in high demand across furniture manufacturing, advertising structures, commercial construction, and other industrial sectors.

• Small Diameter Aluminum Tubes (up to 20 mm):
  Frequently utilized for lightweight assemblies such as tent frameworks, small framing units, or decorative accents. Popular sizes include: 10 mm x 1 mm; 12 mm x 2 mm; 15 mm x 2 mm.
• Medium Diameter Aluminum Tubes (20 mm – 50 mm):
  A highly versatile range, widely favored for manufacturing furniture, fencing, handrails, and other structures requiring a perfect balance between mechanical strength and low weight. Popular sizes include: 20 mm x 1.5 mm; 20 mm x 2 mm; 32 mm x 1 mm; 40 mm x 2 mm; 50 mm x 2 mm.
• Large Diameter Aluminum Tubes (above 50 mm):
  Applied in heavy-duty or industrial structural configurations, such as construction framing, ventilation ducting systems, or load-bearing upright supports. Popular sizes include: 60 mm x 3 mm; 80 mm; 100 mm.

When selecting an aluminum profile or tube, the wall thickness is a critical metric alongside the outer diameter:

• Thin-Walled Tubes (1–2 mm): Lighter in weight and optimized for applications where minimizing mass is critical.
• Thick-Walled Profiles (3 mm and above): Provide significantly higher structural integrity and load-bearing capacity.

Core Alloy Grades for Round Aluminum Tubes

The following alloy grades have gained the widest recognition and are suitable for manufacturing round tubes with any required wall thickness:

Aluminum Tube Grade AD31T (International Equivalent: 6063 / 6060)

This is the absolute most popular alloy grade for extruded aluminum tubes on the Ukrainian metal market.

• Key Characteristics: Outstanding extrudability (enabling the production of precision hollow shapes), exceptional atmospheric corrosion resistance, excellent response to anodizing, and flawless weldability.
• Fields of Application: Ideally suited for architectural and decorative purposes, window framing, high-end furniture manufacturing, and lightweight structural assemblies where extreme mechanical strength is not a primary requirement.

Aluminum Tube Grade 6061 (International Equivalent: AV / AD33)

This is a medium-to-high strength structural alloy.

• Key Characteristics: Enhanced mechanical strength (higher than 6063), excellent weldability, and superior corrosion resistance, including reliable performance in marine environments.
• Fields of Application: Widely utilized in industrial process piping, hydraulic fluid systems, as well as structural framing components for bicycles, motorsport, and the automotive sector.

Aluminum Tube Grade D16T (International Equivalent: 2024)

This is a high-strength duralumin alloy precisely engineered with copper additions.

• Key Characteristics: Outstanding ultimate tensile strength and exceptional fatigue resistance. However, it is more susceptible to atmospheric corrosion compared to the 6xxx-series alloys and exhibits challenging weldability profiles.
• Fields of Application: Extensively applied in aircraft manufacturing, aerospace engineering, and other critical structural assemblies where peak strength-to-weight ratios are vital.
