Compare all 4 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
As fabricated | Standard supply condition for A360 die castings — use for thin-wall pressure-tight housings needing strength above ADC12. | 165 | 317 | 3.5 | 75 HB | 29 % IACS |
Stress relieved | Standard condition for printed AlSi10Mg parts that must hold tight tolerances after machining — lower stress, more ductility. | 215 | 345 | 8 | 95 HB | 31 % IACS |
Solution heat treated and artificially aged | Choose for printed or gravity-cast AlSi10Mg needing isotropic, stable properties; not applied to gas-porous high-pressure die castings (blistering risk). | 235 | 335 | 8 | 100 HB | 35 % IACS |
As built (as printed) | Pick for printed AlSi10Mg parts used straight off the machine — highest strength but high residual stress and anisotropy. | 255 | 430 | 5 | 114 HB | 26 % IACS |
What is A360?
A360 (A360.0, AlSi10Mg) is a low-iron Al-10Si-Mg die-casting alloy with high die-fill fluidity and pressure tightness, and higher strength and corrosion resistance than common ADC12-type alloys. The magnesium gives usable as-cast strength and better polishing and pre-anodize preparation, and the same composition is one of the most widely used aluminium alloys for laser powder bed fusion (L-PBF). Limits are low elongation, porosity in high-pressure die castings that restricts fusion welding and solution heat treatment, abrasive silicon that shortens tool life, and a dark grey anodic film. A380 is the lower-cost die-casting alternative. A360 has a density of 2.63 g/cm³ (0.095 lb/in³), lighter than 95% of aluminum grades. It melts at 557°C (1,035 °F). A360 has a yield strength of 165 MPa (23.9 ksi) and a tensile strength of 317 MPa (46 ksi) — weaker than 58% of aluminum grades. Elongation at break is 3.5% and the elastic modulus is 71 GPa (10.3 Msi).

Working with A360
Is A360 easy to machine?
Machines freely with sharp positive-rake tools and flood coolant, but 9–10 % Si is abrasive — use PCD or polished carbide and expect built-up edge with soft alloy chips.
Can A360 be welded?
TIG/MIG with 4043 or 4047 filler works on printed or low-porosity parts; high-pressure die castings often blister or crack from trapped gas, so favour mechanical joining or adhesive.
Can A360 be formed, bent or molded?
Excellent die-casting fluidity and hot-tear resistance for 1–3 mm walls; keep die temperature and vacuum control tight to limit porosity, and avoid post-cast solution treatment on HPDC parts.
Manufacturability
The process limits FabDigit applies to A360. Every A360 part is priced by an engineer; design inside these and the quote comes back without a redesign loop.

What surface finishes work on A360?
Takes chromate/chrome-free conversion coatings, powder coat and paint well; anodizing gives a dark grey film, so use hardcoat only where wear matters and shot-blast or vibratory finish for cosmetics.

A360 — frequently asked
What is A360 used for?
A360 is typically used for cellphone and electronics housings, cookware, L-PBF printed brackets and manifolds, pressure-tight pump and valve housings, automotive covers and brackets and lighting and heat-sink bodies. In short: pressure die cast Al-Si-Mg.
What is the yield strength of A360?
A360 has a typical yield strength of 165 MPa (23.9 ksi) and a tensile strength of 317 MPa (46 ksi) — weaker than 58% of aluminum grades. Strength varies by condition: see the 4 listed tempers.
Is A360 easy to machine?
Reasonably — machinability is rated good (55/100, worse than 59% of aluminum grades). Machines freely with sharp positive-rake tools and flood coolant, but 9–10 % Si is abrasive — use PCD or polished carbide and expect built-up edge with soft alloy chips.

With care — weldability is rated fair (40/100). TIG/MIG with 4043 or 4047 filler works on printed or low-porosity parts; high-pressure die castings often blister or crack from trapped gas, so favour mechanical joining or adhesive.
