DIN 3.32206 Aluminium Bar- WNr 3.32206 Rods & Round Bars

Product Description

The designation DIN 3.32206 (more accurately standardized as Werkstoffnummer WNr 3.3206 or variations tracking the global EN AW-6063 matrix) represents the premium structural-architectural magnesium-silicon aluminum alloy.

When searching or procuring under the precise WNr 3.32206 / 3.3206 nomenclature for bars, rods, and round profiles, the material is bound tightly to European EN 755 (extruded) or EN 754 (cold-drawn) manufacturing delivery rules.

1. International Standard Mapping

This specification maps directly onto the globally recognized architectural extrusion family:

• Numerical Code: EN AW-6063

• WNr (Werkstoffnummer): 3.3206 / 3.32206

• Traditional DIN 1725-1 Baseline: AlMgSi0.5 (or AlMg0.7Si depending on regional silicon tolerances)

• AISI/SAE (US): 6063

• UK (BS): HE9

2. Chemical Composition Parameters

The alloy relies on an tightly balanced magnesium-to-silicon ratio to generate the $Mg_2Si$ precipitates required for heat-treatment hardening while minimizing excess elements that might compromise surface polishing or anodizing quality.

3. Mechanical Property Benchmarks (Bars & Rods)

The mechanical capabilities of a WNr 3.32206 bar or rod are entirely dependent on its delivery temper. The most frequent commercial profiles for machining and structural trim are T5 and T6.

4. Processing & Manufacturing Attributes

• Extrudability & Surface Polish: The defining feature of WNr 3.32206 is its excellent performance through extrusion dies. It yields complex round, hollow, or customized geometric profiles with virtually zero surface scoring. It accepts decorative, architectural, and hard-coat anodizing beautifully.

• Machinability: While it can be machined readily, it is softer and more ductile than structural 6082 (AlSi1MgMn) or copper-heavy 2011/2024 variants. To avoid long, continuous ribbon chips ("bird-nesting") on a lathe, high cutting speeds paired with sharp, polished carbide tools specifically ground for aluminum are highly recommended.

• Cold Work Formability: In the soft O (annealed) or T4 conditions, the rod stock exhibits outstanding cold malleability, allowing it to be bent or hydroformed into intricate chassis elements or consumer product curves without localized fracturing.

5. Typical Engineering Deployments

• Architectural Components: Complex door frameworks, premium window extrusion systems, handrails, and shop fittings.

• Electrical Utilities: Heavy-duty conduits, electrical busbars, and heat-sink blocks due to its high thermal and electrical conductivity.

• Fluid Systems: Irrigation tubing, pneumatic cylinders, and lightweight hydraulic lines.
