summary: 6063 is an aluminium alloy with magnesium and silicon as its main additions, and Alloys International calls it the architectural extrusion alloy. It extrudes into thin walls and intricate shapes and takes the smooth, uniform surface that anodising needs. Its strength is moderate, with a minimum T6 tensile strength of 195 to 215 MPa for the extruded forms in BS EN 755-2 as printed by AZoM, and its welding is rated excellent.
best_for: Architectural extrusions such as window and door frames, rails and trim that need a smooth anodised finish (Alloys International; AZoM).
weakest_at: 'Strength: Alloys International says 6061 is the higher-strength choice for structural parts, and no space-environment, cryogenic or galvanic data were found for 6063.'

gaps:
  - T1 and T83 values were not found. The sources opened print T4, T5 and T6 only. Wikipedia prints T1 values, but it is limited here to composition and history, and the Alcoa datasheet it cites returned 404.
  - The Alloys International T5 and T6 figures are approximate typical values in ksi, printed with a tilde. They are kept in ksi and are not matched to the MPa minima, because no source printed converted values.
  - The BS EN 755-2 minima and the physical values come from an AZoM article that says its data is indicative only. The standard, the ASTM B221 and B429 tables and any manufacturer datasheet with physical values were not opened.
  - No cryogenic strength or conductivity, vacuum outgassing (TML and CVCM), atomic-oxygen, thermal-vacuum or flight data for 6063 were found in the sources opened.
  - No galvanic, alkali, acid, marine or stress-corrosion data for 6063 were found. The corrosion entries are qualitative statements only.
  - Anodising is recorded only as qualitative statements (excellent, easily anodised). No anodic film thickness, sealing or colour data were found.
  - No figure for strength loss in the heat-affected zone after welding was found in a source opened for this profile.
  - 'Designations: AZoM also prints GS10, A-GS, HE19, AlMgSi0.5 and 3.32206 without naming their systems, or they conflict with other sources (3.32206 against 3.3206 from Alloys International; HE19 against HE9 in Wikipedia). They are not recorded. The AZoM list covers 6063 and 6063A together, so the ASTM, MIL, QQ and SAE rows should be checked against the standards.'
  - 'Critical minerals: the USGS 2025 list page returned 403 and was not read. The USGS silicon chapter says silicon was added in 2025. The 2025 status of aluminium and magnesium is not printed in the chapters read. The EU 2023 list prints bauxite, magnesium and silicon metal, but not aluminium.'
  - Hazards are element-level PubChem GHS data for aluminium, magnesium and silicon. No safety data sheet for 6063 was opened, and hazards from dust or fumes produced by machining or welding were not found.
  - Supply shares are calculated by Space Mushroom from USGS tables that print tonnages and world totals. The USGS recycling figures are for aluminium and magnesium in general, not for 6063 scrap.
  - Brinell hardness values printed by AZoM are not recorded, because hardness is not in the property list.
  - 'Not reached in this run: the Alcoa datasheet (404), MatWeb (403) and the USGS 2025 critical-mineral list page (403).'

  risk_groups:
    - title: For people
      lead: No safety data sheet for 6063 was opened. Element-level PubChem GHS data for aluminium, magnesium and silicon is in the hazards list.
      gap: Hazard classification of 6063 as supplied, and of dust or fumes from machining or welding, was not found.
      points:
        - label: What the sources cover
          line: The sources describe finish, corrosion, extrusion and welding behaviour, not health effects. Read the supplier's safety data sheet before cutting, grinding or welding.
    - title: If it fails
      lead: Failure routes that the sources name. None of them is a field-incident record.
      points:
        - label: Movement during machining
          line: Alloys International says thick plate can move when large volumes are removed, and recommends a stress-relieved temper to limit this.
        - label: Corrosion
          line: AZoM and Alloys International both describe good to high corrosion resistance. Neither names an environment that attacks 6063.
        - label: Welding
          line: The sources rate gas, arc and resistance welding as excellent (AZoM). No figure for strength loss near a weld was found in a source opened for this profile.
    - title: Handling and storage
      points:
        - label: Forming and machining
          line: Form in the annealed or freshly solution treated condition where the temper allows, then age to final strength. Cut heat-treatable alloys in the T temper.
        - label: Welding filler
          line: Use 5183 or 4043 filler generally, 4043 where maximum electrical conductivity is needed, and 5346 for strength and conductivity (AZoM).
  why: 6063 is an aluminium alloy with magnesium (0.45 to 0.9 wt%) and silicon (0.2 to 0.6 wt%) as its main additions (AZoM, Table 1). Alloys International calls it the architectural extrusion alloy. Compared with 6061 it has less silicon and magnesium, so it extrudes into thinner walls and more intricate shapes, and it gives the smooth, uniform surface that anodising needs. Its strength is moderate, which is rarely the deciding factor in window frames, rails, trim, heat sinks and enclosures.
  uses:
    - where: Window, door and curtain wall framing
      line: Alloys International lists window, door and curtain wall framing among its typical applications, and AZoM lists window frames and doors.
    - where: Architectural trim, railing and balustrading
      line: AZoM says balustrading rails and posts are normally T6 and formed elbows and bends are T4. T4 is also used for hydroformed chassis tube.
    - where: Heat sinks
      line: Alloys International lists heat sinks and enclosures, where strength is rarely the deciding factor.
  can_do:
    - label: Strength, T6
      line: Minimum tensile strength of T6 rod and bar up to 150 mm is 215 MPa, with a minimum proof stress of 170 MPa (BS EN 755-2 values printed by AZoM). Alloys International's typical T6 figures are about 35 ksi tensile and 31 ksi yield.
      value: 215 MPa minimum tensile; about 35 ksi typical
    - label: Strength, T4
      line: T4 extruded rod and bar up to 150 mm has a minimum tensile strength of 150 MPa and a minimum proof stress of 90 MPa (AZoM).
      value: 150 MPa minimum tensile
    - label: Ductility
      line: Minimum elongation A50 mm is 8% for T6 rod and bar up to 150 mm and 10% for T4 extruded rod and bar (AZoM).
    - label: Weight
      line: Density is 2700 kg/m3 (AZoM, Table 4).
    - label: Stiffness
      line: Modulus of elasticity is 69.5 GPa (AZoM, Table 4).
    - label: Heat conduction
      line: Thermal conductivity is 200 W/m.K (AZoM, Table 4).
    - label: Thermal expansion
      line: The linear thermal expansion coefficient is 23.5 x 10^-6 /K (AZoM, Table 4).
    - label: Anodising
      line: Alloys International calls the anodised finish excellent, and AZoM says 6063 can be easily anodised. No anodic film thickness or sealing data was found.
      value: Excellent (Alloys International)
    - label: Welding
      line: AZoM rates gas, arc and resistance welding as excellent, brazing as excellent and solderability as good. Alloys International says 5xxx and 6xxx alloys weld readily with 4043 or 5356 filler.
      value: Excellent (gas, arc, resistance)
    - label: Machining
      line: AZoM rates machinability and cold workability as average.
  compare: The sources give no strength-per-mass figures for 6063 against other alloys, so this profile does not rank it. Alloys International says 6061 is the higher-strength choice for structural parts. The USGS lists composites, magnesium, steel and titanium as substitutes for aluminium in ground transport, and composites, steel, vinyl and wood in construction.

  handling:
    - 'Machining: cut heat-treatable alloys in the T temper. For thick plate, use a stress-relieved temper to limit movement (Alloys International).'
    - 'Forming: form in the annealed or freshly solution treated condition where the temper allows, then age to final strength (Alloys International).'
    - 'Welding: use 5183 or 4043 filler generally, and 5346 for strength and conductivity (AZoM).'
    - 'Safety: no safety data sheet for 6063 was opened, so read the supplier''s data sheet before cutting or welding.'
  good_for:
    - Architectural extrusions, such as window and door frames, rails and trim, that need a smooth anodised finish (Alloys International; AZoM).
    - Heat sinks, where a thermal conductivity of 200 W/m.K spreads heat (AZoM, Table 4).
    - Welded assemblies, since gas, arc and resistance welding are all rated excellent (AZoM).
  watch_out:
    - Strength is moderate. Alloys International says 6061 is the higher-strength choice for structural parts.
    - The Alloys International strengths are approximate typical values in ksi and are not for design. The AZoM strengths are BS EN 755-2 minima.
    - T1 and T83 values were not found, so the file has no rows for them.
    - No galvanic, alkali or acid data, no space-environment data and no cryogenic values were found for 6063.
  verdict: '6063 is the architectural extrusion alloy: moderate strength, excellent weldability, a finish that anodises well, and good corrosion resistance in general use. The sources give no T1 or T83 values and no space-environment data.'
