Product Name: 6061 T6 Aluminum Extruded Tube
Alloy: 6061
Temper: T6
Production Method: Extruded
Shape: Round Tube
Material: Aluminum
6061 aluminum combines many of the advantageous qualities of aluminum and is one of the most affordable and versatile heat-treatable alloys. It delivers reliable mechanical performance and strong corrosion resistance and can be processed using most standard fabrication methods.
In the annealed state, it offers excellent workability. When in the T4 temper, it can handle relatively demanding forming operations. Full T6 performance is achieved through artificial aging.
When selecting the right aluminum alloy for an extrusion project, choosing the proper grade is essential.
Aluminum alloy 6061 is a heat-treatable, durable alloy known for its excellent formability, weldability, machinability, and strength. 6061-T6 aluminum is the most widely used temper of this alloy. Produced through heat treatment and pre-stretching, 6061-T6 provides reliable performance. Although its strength does not match that of the 2XXX or 7075 series, its magnesium-silicon composition offers excellent processing characteristics. It features superior weldability, good electroplating properties, strong corrosion resistance, high toughness, and stable dimensional performance with no deformation after machining. The material is also easy to polish, paint, and anodize.
For extrusion projects where extremely high strength or premium surface appearance is not required, 6061 aluminum is generally the most practical and widely accepted option. This medium-to-high-strength alloy provides excellent machinability, weldability, and formability. Whether for small extrusion profiles or large structural components, 6061 remains one of the most common choices. Thanks to its strength and corrosion-resistant properties, 6061 aluminum-often called a structural alloy-is ideal for load-bearing applications. From compact LED lighting housings to large railway components, 6061 aluminum sees extensive use across many manufacturing sectors. GNEE supplies high-quality 6061 alloy products for such applications.
