Frequently Asked Questions (FAQ)
-
What is the difference between 7075-T6 and 6061-T6 aluminum tube?
7075-T6 has significantly higher strength (tensile strength ~570 MPa vs 260 MPa for 6061) but lower corrosion resistance and weldability. It is ideal for high-stress applications where weight is critical. -
Can you cut the tube to custom lengths?
Yes, we can provide custom lengths according to your requirements. Please specify your desired length when ordering. -
What surface treatments are available?
Standard mill finish is offered. Optional treatments include anodizing (clear or colored), powder coating, and painting, available upon request. -
Is this tube suitable for welding?
7075-T6 is not recommended for general welding as it can suffer from heat-affected zone cracking. For welded assemblies, we suggest considering 6061-T6 or other weldable alloys. However, special techniques like friction stir welding may be used with caution. -
What is the minimum order quantity (MOQ)?
Our MOQ for 7075-T6 tubes is typically 100 kg for standard sizes, but smaller quantities may be arranged for sample orders. Please contact us for details. -
Do you provide a certificate of compliance or material test report?
Yes, we can provide a certificate of compliance and a mill test report (MTR) for each batch, confirming the chemical composition and mechanical properties. -
How is the tube packaged for shipment?
We use strong waterproof wrapping, with wooden pallets or crates for large orders. Each tube is protected with foam or corrugated board to prevent scratches and damage during transit. -
What is the typical lead time for a 6-meter length order?
Lead time is typically 7–15 days after order confirmation, depending on quantity and current production schedule. We strive to meet urgent requests when possible.
