Aluminum 3003 Small Diameter Tubing

Aluminum 3003 Small Diameter Tubing

Enhanced Strength with Excellent Workability — from International Tube

At International Tube, we manufacture high-quality Aluminum 3003 small diameter tubing (UNS A93003), a manganese-alloyed aluminum known for its increased strength, superior corrosion resistance, and excellent formability. As a non-heat-treatable alloy, Aluminum 3003 offers reliable mechanical performance while maintaining the lightweight benefits aluminum is known for, making it ideal for a wide range of industrial and commercial applications.

With the addition of approximately 1.2% manganese, Aluminum 3003 is significantly stronger than commercially pure 1100 aluminum, yet it remains highly workable and weldable. It performs well in cold-working and bending processes and offers solid resistance to atmospheric and chemical corrosion, particularly in marine and industrial environments.

Aluminum 3003 Tubing Features & Applications

Aluminum 3003 tubing from International Tube is a dependable choice for applications where lightweight strength and corrosion resistance are required without sacrificing workability. Common applications include:

• HVAC and refrigeration systems

• Architectural and structural tubing

• Roofing and siding drain systems

• Food and beverage processing equipment

• Automotive fuel and transmission lines

• Storage tanks and piping

• Chemical handling and utility lines

Our small-diameter Aluminum 3003 tubing is manufactured using high-quality strip stock, plug drawn in coil form, and annealed as required to meet specific temper and performance needs. Tubing is available in both straight lengths and continuous coil form, ideal for flexible integration into manufacturing and assembly operations.

When your application calls for a balance of formability, corrosion resistance, and enhanced strength, trust International Tube to deliver Aluminum 3003 tubing with consistent quality and precision.
