6061 Aluminum Plate is made from one of the most versatile of all of the aluminum alloys. 6061 Aluminum Plate is the alloy of desire for all-reason packages. 6061 Aluminum Plate is an aluminum-silicon-magnesium alloy, reinforced by precipitation hardening. This alloy has medium strength, formability, weldability, machinability and corrosion resistance. 6061 Aluminum plate is used for tooling plate, architectural applications, transportation device, bridge railing additives, and is beneficial in welded structural application. We stock 6061 Aluminum Plate in thickness .250'' via 12'' thick in inventory available for fast transport.
Our 6061 plate has T651 temper, indicating it has been solution warmth treated followed by using a minimal stretching to reduce stresses inside the material. The material becomes then artificially aged to allow the alloying elements to precipitate out of the material, to give on the spot maximum strength.
Reading the text: “Immediate maximum strength” means maximum strength after ageing. The page title says T6, but the plate described is T651, which is T6 with a stress-relieving stretch.
6061-T651 Aluminum plate has a tensile strength range of 42-45 KSI, and conforms to AMS QQ-A-250/11, ASME SB209, and ASTM B209
6061-T6 Aluminium Plates: Purchasing Specification

How the Eighteen Aluminium Alloys Differ
The eighteen pages cover aluminium alloys from several families. The 1xxx, 3xxx and 5xxx alloys are non-heat-treatable and gain strength by cold work, while the 2xxx, 6xxx and 7xxx alloys are heat-treatable. The 5xxx magnesium alloys are the usual marine and welded-structure choice; the 2xxx and 7xxx alloys are the high-strength aerospace alloys.
| Alloy | Family and hardening | Typical use (from the pages) |
|---|---|---|
| 1050A | 1xxx pure aluminium (99.5%), non-heat-treatable | General sheet-metal work, packaging, heat transfer, kitchenware |
| 1350 | 1xxx electrical-grade aluminium (99.5% min), non-heat-treatable | Transformer and switchgear conductors |
| 2024 | 2xxx aluminium-copper, heat-treatable | Aircraft structure, precision fittings, truck wheels |

| 2219 | 2xxx aluminium-copper, heat-treatable | Space boosters, fuel tanks, high-temperature structures |
| 3003 | 3xxx aluminium-manganese, non-heat-treatable | Heat exchangers, catwalks, food and chemical equipment, roofing |
| 5052 | 5xxx aluminium-magnesium, non-heat-treatable | Fuel tanks, truck panels, small boat hulls, pressure vessels |
| 5083 | 5xxx aluminium-magnesium (4.0–4.9% Mg) | LNG ships, pressure vessels, storage tanks, welded structures |
| 5086 | 5xxx aluminium-magnesium (3.5–4.5% Mg) | Shipyard work, tank cars, patrol and work-boat hulls |
| 5154 | 5xxx aluminium-magnesium (3.1–3.9% Mg) | Wire, rivets and cold-heading applications |
| 5454 | 5xxx aluminium-magnesium (2.4–3.0% Mg) | Road transport, chemical plant, pressure vessels, marine and off-shore |
| 5456 | 5xxx aluminium-magnesium (about 5% Mg) | Welded structures, low-temperature service |
| 5754 | 5xxx aluminium-magnesium (2.6–3.6% Mg) | Treadplate, shipbuilding, vehicle bodies, food processing |
| 6061-T6 (this page) | 6xxx aluminium-magnesium-silicon, heat-treatable | Tooling plate, architectural, transport, welded structures |
| 7050 | 7xxx aluminium-zinc-magnesium-copper, heat-treatable | Aerospace fuselage frames and bulkheads |
