6065 aluminiumlegering

What Is 6065 Aluminum Alloy?

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.

Mechanische eigenschappen per hardingsgraad

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.

Temper	Treksterkte (MPa)	Opbrengststerkte (MPa)	Elongation (%, min)
O	~120	~70	~18
T6	260 – 310	~240	10 – 11

Shear strength for T6 is around 190 MPa.

Gids voor het kiezen van de juiste temperatuur

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.

Belangrijkste kenmerken

Balanced Strength & Machinability

6065 offers a useful strength level while the bismuth addition keeps chips manageable during machining.

Corrosiebestendigheid

As a 6000-series alloy it resists corrosion well in normal atmospheric and industrial environments.

Vormbaarheid en lasbaarheid

In the O temper the alloy forms readily; it welds with standard methods, with some local softening in the heat-affected zone.

Toepassingen

• Marine and engine-adjacent structures
• Aircraft and vehicle components
• Building frameworks and supports
• Truck bodies and rail cars
• Structural and industrial fabrications

Opmerkingen over bewerking en oppervlakteafwerking

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.

Kwaliteitsdocumenten en inspectie

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.

Why Choose Linsy for 6063 Aluminum

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.

6065 Aluminum FAQ

What tempers are available for 6065?

We commonly supply O and T6 across sheet, tube, bar, and wire.

How does 6065 compare with 6061?

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.

Is 6065 suitable for marine use?

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.

Veelgestelde vragen over bestellingen in het algemeen

Wat is de gebruikelijke levertijd?

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.

Do you provide an MTC with each order?

Yes. A Mill Test Certificate is issued for every shipment, reporting chemical composition and mechanical properties for the supplied heat.

Can sizes and tempers be customized?

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.

Which surface finishes are available?

Common options include mill finish, anodizing, and polishing. Specific finishes should be confirmed against your application and tolerance needs.

Which certifications does Linsy hold?

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.
