FAQs

What Is The Minimum Order Quantity For 6061 Aluminum Rectangular Tubing? Do You Support Small Batches?

Chalco maintains stock of 6061-T6 tubing; standard MOQ for stocked sizes is 200 kg, with fast prototyping support for smaller samples. Custom products typically require a 1-ton MOQ, but we can flexibly accommodate trial runs and small-to-medium batch orders.

What Is The Typical Price Of 6061 Aluminum Rectangular Tubing?

Pricing for 6061 aluminum rectangular tubing varies by size, wall thickness, temper, and order quantity. Typical range is $2.5–$12.5/ft. Chalco offers tailored quotes—please submit your specifications for a rapid price estimate.

Is The Structural Strength Of 6061 Rectangular Tubing Sufficient To Replace Steel?

In T6 temper, 6061 rectangular tubing achieves tensile strength ≥ 290 MPa and yield strength ≥ 240 MPa, making it suitable for load-bearing frames and equipment supports. With proper wall thickness and design support, it can serve as a lightweight alternative to carbon steel in transportation, construction, and equipment manufacturing.

Is 6061 Rectangular Tubing Suitable For Humid Or Corrosive Environments?

Yes. 6061 has a natural oxide layer that resists atmospheric, moisture, and mild chemical corrosion. For salt spray or marine conditions, we recommend anodizing or powder coating, or consider using 5083 alloy for enhanced corrosion resistance.

What Advantages Does 6061 Have Over 6063 Rectangular Tubing?

Compared to 6063, 6061 offers higher strength and greater structural rigidity, making it ideal for load-bearing and mechanical applications. 6063 Rectangular Tubing is better suited for decorative, lightweight structures with stringent surface-finish requirements. For projects involving CNC machining, welding, or structural support, 6061 is the preferred choice.

Does 6061 Rectangular Tubing Support Surface Treatments Like Anodizing Or Electrophoresis?

Yes. Chalco provides anodizing (up to 50 μm), black electrophoretic coating, powder coating, and other finishes to enhance corrosion resistance and aesthetic appeal, meeting demands in architecture, marine, and high-end equipment applications.

Can You Custom-Size 6061 Rectangular Tubing According To My Drawings?

Absolutely. With over 1, 000 die sets covering most profiles, Chalco can produce standard sizes immediately. For non-standard dimensions, special wall thicknesses, or unique profiles, we offer quick die-making and sample runs with 15–20 working day turnaround.
