6061 T6 Aluminium Sheet Description
Certified ASTM B209 6061 Aluminum Plate
GNEE Aluminum is a premier manufacturer and large-scale supplier of 6061-T6 Aluminum Sheet and Plate. As one of the most versatile heat-treatable alloys, our 6061 aluminum provides a superior blend of high strength, excellent corrosion resistance, and exceptional weldability. We specialize in 6061-T651 stress-relieved plates, ensuring zero deformation during high-speed CNC machining.
Why Professionals Choose GNEE 6061 Aluminum
Zero-Deformation Machining
Our 6061-T651 plates undergo a controlled stretching process after heat treatment. This eliminates residual internal stresses, meaning the plate stays perfectly flat even after heavy CNC milling or deep pocketing.
Superior Surface Quality
GNEE 6061 aluminum sheets are free from pits, scratches, and oxidation. For precision components, we offer fine-milled surfaces with high-precision flatness control (within 0.5mm/m).
Excellent Weldability & Corrosion Resistance
6061 is highly weldable using TIG or MIG techniques and offers excellent resistance to atmospheric corrosion and seawater, making it the "gold standard" for structural and marine components.
Diverse Applications of 6061 Aluminum Sheet
- Precision Machining: Jigs, fixtures, base plates, and CNC machined components for automated equipment.
- Transportation: Truck frames, trailer components, and automotive structural parts.
- Marine & Aerospace: Ship decks, bulkheads, and light aircraft fuselage structures.
- Industrial Structures: Walkways, platforms, and heavy-duty structural assemblies.

FAQ: Technical Guide for 6061 Aluminum Sheet
Q1: What is the difference between 6061-T6 and 6061-T651?
A: T6 is standard heat-treated. T651 is T6 state plus a 1.5%–3% stretching process to remove internal stress. T651 is essential if you are doing extensive CNC machining to prevent the material from "walking" or warping.
Q2: Does 6061 aluminum have good corrosion resistance?
A: Yes, 6061 has very good resistance to atmospheric corrosion. While not as high as 5083 in pure seawater, it is widely used in marine environments when structural strength is also required.
Q3: Can 6061 aluminum be anodized?
A: Absolutely. 6061-T6 is excellent for anodizing. It accepts clear, black, and color anodizing very well, providing a uniform and durable finish.
