FAQs – Aluminium Pipes & Tubes

Pipe vs Tube	Pipes are typically specified by nominal bore/schedule; tubes are specified by exact OD & wall thickness for precision applications.
Seamless vs Welded	Seamless/drawn tubes are preferred for pressure/precision; welded tubes are typically used for non-critical and cost-sensitive applications.
Best Alloy for Heat Transfer	3003 is commonly used for heat exchangers and radiators due to good formability and thermal performance.
Best Alloy for Strength	6061 offers a strong balance of strength and weldability; 7075/7050 are very high strength but are generally less preferred for welding-critical joints.
Do You Offer Cut-to-Size?	Yes, cut-to-length, deburring/chamfering, and export packing can be provided as per order requirements.
