6061 Aluminum Sheets | T6 & T651 Plate Supplier – HXM Aluminum

6061-T6 is solution heat-treated and artificially aged, providing a tensile strength of 290 MPa. 6061-T651 undergoes the same heat treatment but includes a stretching process (1-3% permanent set) to relieve internal stresses. T651 is preferred for precision machined components because it maintains better dimensional stability during machining, reducing warpage and distortion.

HXM Aluminum supplies 6061 aluminum sheets from 0.5mm to 200mm thick. Sheets below 6mm are classified as “sheet,” while 6mm and above are classified as “plate.” Both are available in T6, T651, T4, and O temper conditions with widths up to 2500mm and custom cut lengths up to 12000mm. Standard stock sizes include 1000×2000mm, 1250×2500mm, and 1500×3000mm.

Yes, 6061 aluminum has excellent weldability using TIG, MIG, and resistance welding methods. For 6061-T6 sheets, welding typically reduces the strength in the heat-affected zone (HAZ) to near O-temper levels. 4043 or 5356 filler wire is recommended. Post-weld heat treatment can restore T6 properties in the weld zone if required.

Yes, 6061 aluminum sheet offers good resistance to marine atmospheres due to its magnesium-silicon composition. It is widely used for boat hulls, deck plates, and marine structural components. For prolonged immersion in seawater, 5083 or 5086 alloys may offer superior corrosion resistance, but 6061 provides an excellent balance of strength and corrosion resistance for most marine applications. Anodizing or powder coating further enhances marine durability.

In T6 temper, the minimum bend radius is approximately 3.0 times the sheet thickness (e.g., 6mm for a 2mm sheet). In O (annealed) temper, the minimum bend radius reduces to 1.0 times the thickness, allowing tight bends without cracking. T4 temper offers an intermediate bend radius of approximately 2.0 times the thickness. For complex forming operations, we recommend using O temper and subsequently heat-treating to T6.

Submit your requirements including: alloy and temper (e.g., 6061-T6), thickness, width, length, quantity, surface finish requirement, and delivery destination.

Our 6061 aluminum sheets comply with ASTM B209 (American), EN 573-3 (European), and GB/T 3880 (Chinese) standards. Each shipment includes a Mill Test Certificate (EN 10204 3.1) documenting chemical composition, mechanical properties, and dimensional tolerances.

Yes, 6061 aluminum has excellent anodizing response, producing a uniform protective oxide layer. HXM Aluminum offers clear anodizing, colored anodizing (bronze, black, gold, etc.), and hard anodizing services. Anodizing thickness typically ranges from 5 to 25 microns depending on the application requirements.

T4 is solution heat-treated and naturally aged — provides good formability with moderate strength (241 MPa UTS). Can be formed after solution treatment and then artificially aged to T6. 

T6 is solution heat-treated and artificially aged — offers maximum strength (290 MPa UTS), the most common temper for structural applications. 

T651 is stress-relieved by stretching (1-3% permanent set) after solution treatment — provides the same strength as T6 but with improved dimensional stability for precision machining.

Choose T4 for forming operations, T6 for general structural use, and T651 for CNC machined components.

Yes, we offer fully custom sizes — any thickness from 0.5mm to 200mm, any width from 500mm to 2500mm, and any length up to 12000mm. We also provide CNC laser cutting, milling, drilling, bending, and surface treatments. Custom packaging for export is available.
