6061-T6 T651 Aluminum Round Bar Description
Stop Worrying About Warping During CNC Machining.
While standard 6061 aluminum is versatile, GNEE specializes in 6061-T651 Aluminum Bars. By applying a controlled stretching process (1.5%-3%) after heat treatment, we eliminate internal residual stress. This means our bars stay flat and true, even after heavy material removal.
Ideal for: Automated mechanical parts, SMT carriers, Precision jigs, and Aerospace fixtures.
Key Features of 6061-T6 6061-T651 Aluminum Round Bar
True 6061 T651 Temper (No Deformation):
Guaranteed stress relief. Perfect for manufacturing precision parts that require tight geometric tolerances. No warping after machining.
Precision Tolerance (h9 / h11):
Diameter tolerance is strictly controlled to ISO h9 or h11 standards. Ready for automatic bar feeders with no jamming.
Surface Finish:
Available in Mill Finish (smooth), Cold Drawn (bright), or Polished. Free from oil stains, dents, and heavy extrusion lines.
Internal Integrity:
100% Ultrasonic Testing (Class A) available upon request. No porosity, no cracks, no sand holes.

6061 and 6063 are the two most popular extrusion alloys. 6063 aluminum occupies the number one spot and 6061 occupies spot number two. As alloys in the 6000 series, they both have magnesium and silicon as their primary alloying elements. Thus, they have many similar properties. 6061 offers higher strength, however. As such, it is often used for more structural applications. 6063, on the other hand, is used for applications such as railing or trim, windows, and doors, due to its better appearance and corrosion resistance.
