Material grade
6061
Grade of Aluminum. Grades are not interchangeable.
Aluminum 6061 is a heat-treatable Al-Mg-Si alloy used for machined housings, brackets, frames and general industrial parts. Buyers usually call out the temper as well as the grade, most often T6 for machined components. On Metraxio, 6061 is a grade under aluminum. Tempers such as T6 are not separate grade pages.
Grade overview
6061 is chosen when a part needs a practical balance of strength, corrosion resistance and machinability, and when the design can use a wrought product: plate, bar or extrusion. It is a common CNC milling and turning grade. It is also formed and welded in some tempers, with the understanding that welding changes the local temper. It is not a die-casting alloy. If the drawing says 6061 and the process is high-pressure die casting, the material and the process disagree and should be resolved in the project.
Metraxio does not publish tensile or yield numbers on this page. Those values depend on the product form, the temper and the standard named on the drawing. Ask for the standard and, when traceability matters, an EN 10204 Type 3.1 certificate or the equivalent you actually require.
Typical manufacturing routes
Typical routes are CNC milling, CNC turning and 5-axis machining from plate, bar or a cut extrusion. Sheet parts may be laser cut and bent. Anodizing is a frequent subsequent finish and is a separate surface-treatment capability. Die casting is a different aluminum family.
Machinability and process constraints
6061 in the T6 temper is widely machined and holds threads and pockets well when the tool and the workholding suit the feature. Thin walls and deep pockets still move. Extruded profiles can have grain and distortion that plate does not. State the product form. Do not treat a machined-from-plate tolerance as automatic for a bent sheet part.
Typical applications
Typical parts are machine brackets, manifolds, inspection fixtures, electronic housings, frames and general OEM hardware. Aerospace or pressure applications may need a different alloy or a named specification even when 6061 would machine easily. The application belongs in the project notes when it changes the certificate or the finish.
What to include in the manufacturing project
State 6061, the temper, the product form, the quantity, the drawing and the finish, including anodize type and color when appearance or corrosion protection matters. Identify critical dimensions. Link related grades only when they are genuine alternatives, such as 6082 for some structural parts or 7075 when higher strength is the reason for a change. A substitute is a buyer decision, not an assumption.
Buyer questions
Is 6061-T6 a different grade page?
No. T6 is a temper. Metraxio keeps 6061 as the grade and sends temper URLs to this page. Write the temper in the manufacturing project.
Can I substitute 6082?
Sometimes, for structural duties where 6082 is the local stock. It is a different alloy. Accept it only if your drawing or your customer allows the change.
Does this page mean 6061 is in stock?
No. It explains how to specify the grade. Availability is a sourcing question after the requirement exists.
Should I ask for mechanical properties?
Ask for the standard and the certificate that apply to your part. This page does not invent strength numbers, because they depend on form and temper.
