FAQ
Most enquiries reduce to a small set of recurring technical questions.
01 What is 6061 aluminum tube?
6061 (EN AW-6061 / AlMg1SiCu) is a magnesium-silicon-copper 6xxx aluminum alloy supplied as drawn seamless tube (ASTM B210) or extruded tube (ASTM B221). In the T6 temper it offers a balanced combination of strength, weldability, machinability and corrosion resistance.
02 What shapes of 6061 tube are available?
Round is the standard shape. Square and rectangular tube are available on request. Outside diameters typically range from 6 mm to 250 mm for drawn seamless tube, with larger sizes available as extruded tube.
03 What is the difference between drawn seamless and extruded tube?
Drawn seamless tube (ASTM B210) is produced by cold drawing a pierced billet, giving tighter dimensional tolerance and a smoother surface finish. Extruded tube (ASTM B221) is produced by hot extrusion through a die and is typically used for larger sizes and thicker walls where tight tolerance is less critical.
04 Is 6061 tube suitable for welded fabrication?
Yes. 6061 tube is weldable using appropriate filler alloys (e.g. 4043 / 5356) and procedures. For pressure or fluid handling service where applicable, the relevant design code and qualification procedure must be followed.
05 Is 6061 tube suitable for heat exchanger service?
6061 is used for industrial heat exchanger and condenser tubing where its combination of thermal conductivity, mechanical strength and corrosion resistance is suitable for the service conditions. The specific application, medium and design code must be evaluated by the project engineer.
