6065 aluminum is a heat-treatable 6000-series alloy built on the magnesium-silicon base with bismuth added for improved machinability. It balances moderate strength, corrosion resistance, and good chip control during machining, which suits structural and industrial components. Linsy supplies 6065 in O and T6 tempers across sheet, tube, bar, and wire.

Dimensions can be customized. Share your required form, temper, and size and we will confirm feasibility and tolerance.
| Standard | Denominazione |
|---|---|
| 6–400 mm | 6065 / A96065 |

Typical composition of 6065 is listed below. Bismuth is added to support machining; exact limits should be confirmed against the ordered specification.
| Elemento | Composizione (wt%) |
|---|---|
| Si | 0.40 – 0.90 |
| Fe | 0.70 max |
| Cu | 0.15 – 0.40 |
| Mn | 0,15 max |
| Mg | 0.80 – 1.20 |
| Cr | 0,15 max |
| Zn | 0,25 max |
| Bi | 0.40 – 0.70 (typical) |
| Ti | 0,10 max |
| Altri (ciascuno) | 0,05 max |
| Altri (totale) | 0,15 max |
| Al | Resto |
Values below are typical reference ranges; actual results vary with section thickness and temper. T6 figures are taken from the supplied specification, while O values are typical annealed references to be confirmed.
| Temperamento | Resistenza alla trazione (MPa) | Resistenza allo snervamento (MPa) | Elongation (%, min) |
|---|---|---|---|
| O | ~120 | ~70 | ~18 |
| T6 | 260 – 310 | ~240 | 10 – 11 |
Shear strength for T6 is around 190 MPa.
O (annealed) gives maximum formability and is chosen where the part is bent or formed before any service load. T6 is the aged temper that delivers the strength and stability needed for structural and machined parts. Select T6 for load-bearing use and O where forming dominates.
6065 offers a useful strength level while the bismuth addition keeps chips manageable during machining.
As a 6000-series alloy it resists corrosion well in normal atmospheric and industrial environments.
In the O temper the alloy forms readily; it welds with standard methods, with some local softening in the heat-affected zone.
6065 machines with good chip control; use aluminum-appropriate tooling and speeds. Forming is best done in O temper before aging. Anodizing and polishing are supported — confirm finish and tolerance needs up front. Welding is straightforward but reduces local strength; design around the heat-affected zone when load matters.
Every 6063 square bar shipment leaves our Shenzhen plant with a Mill Test Certificate (MTC) that reports the actual chemical analysis and mechanical results for the heat. In-house checks cover dimensional tolerance, surface condition, and temper verification. Our production system is managed under ISO 9001, ISO 14001, and ISO 45001. Where a project requires it, third-party test reports (for example SGS) can be arranged on request.
Linsy is a Shenzhen-based aluminum supplier with more than 20 years of production experience across the 1000 to 8000 series. For 6063 we support both standard extruded profiles and made-to-order sections, with in-house cutting, CNC machining, and anodizing or polishing finishes. Common tempers and sizes are held for faster turnaround, while custom dimensions are produced to order. Each order ships with an MTC so procurement and quality teams can verify the material before it enters production.
For deeper background on this alloy, see our guide: 6065 Alluminio: Una guida essenziale per gli ingegneri. It covers temper selection, machining notes, and typical application examples useful when specifying material.
We commonly supply O and T6 across sheet, tube, bar, and wire.
Both are 6000-series Mg-Si alloys. 6065 includes bismuth for better machining and is often selected where machinability is a priority; 6061 is the broader general-purpose structural choice.
It offers good general corrosion resistance for many structural uses; for aggressive marine exposure, confirm the environment and any coating or alloy-substitution needs with our team.
Standard tempers and sizes are usually available within 10–60 days. Custom extrusion or machining lead times depend on section complexity and order volume — we confirm a date when the specification is fixed.
Yes. A Mill Test Certificate is issued for every shipment, reporting chemical composition and mechanical properties for the supplied heat.
Yes. We cut to length and produce custom cross-sections and tempers on request. Share your drawing or required dimensions and we will confirm feasibility.
Common options include mill finish, anodizing, and polishing. Specific finishes should be confirmed against your application and tolerance needs.
Our management system is certified to ISO 9001, ISO 14001, and ISO 45001. Third-party test reports such as SGS can be provided on request for specific orders.
