Compare all 5 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
F | Low-volume or large sand castings; slow cooling coarsens the structure so strength is the lowest of the three routes. | 95 | 150 | 1 | 60 HB | 22 % IACS |
F | Pick for gravity die (permanent mould) castings where wall sections are thicker and pressure tightness matters more than peak strength. | 110 | 200 | 1 | 80 HB | 23 % IACS |
F-DDefaultThis page F | Default condition: thin-wall high-pressure die castings used as cast, no heat treatment. | 155 | 270 | 1.5 | 85 HB | 24 % IACS |
Cooled from hot working and artificially aged | Use when dimensional stability after machining or a modest yield gain is needed without risking blistering of gas-porous die castings. | 190 | 275 | 1 | 95 HB | 25 % IACS |
Solution heat treated and artificially aged | Only for low-gas castings (vacuum/high-integrity HPDC, squeeze or gravity cast) where maximum strength and hardness are required; conventional die castings blister. | 240 | 300 | 1 | 110 HB | 28 % IACS |

Working with EN AC-46000 F-D
Is EN AC-46000 easy to machine?
Machines freely with sharp PCD or uncoated carbide tooling at high speed; the eutectic and primary Si are abrasive, so PCD is standard for high volumes, and porosity can be exposed in machined sealing faces.
Can EN AC-46000 be welded?
Essentially not fusion weldable as a die casting — entrapped gas causes blowholes and the Cu content promotes hot cracking; use mechanical joining, adhesive bonding, self-pierce riveting or friction stir/laser only on high-integrity vacuum castings.
Can EN AC-46000 be formed, bent or molded?
Outstanding HPDC alloy: fluid at 660–700 °C melt / 200–240 °C die, tolerates 1 % Fe to resist die soldering, wall sections down to ~1.5 mm, and takes high recycled charge.
What surface finishes work on EN AC-46000?
Best finished by chromate-free conversion coating plus e-coat/powder paint; decorative anodizing is poor (dark grey), electroless nickel or zinc-based plating is used for wear/EMI, and shot blasting or vibratory finishing evens the as-cast skin.

EN AC-46000 F-D — frequently asked
What is EN AC-46000 F-D used for?
EN AC-46000 F-D is typically used for engine blocks, transmission cases, housings and automotive brackets. In short: most common HPDC alloy; tolerates recycled, high-Fe charge; not fusion weldable as-cast.
What is the yield strength of EN AC-46000 F-D?
EN AC-46000 F-D has a typical yield strength of 155 MPa (22.5 ksi) and a tensile strength of 270 MPa (39.2 ksi) — weaker than 63% of aluminum grades. Strength varies by condition: see the 5 listed tempers.
Is EN AC-46000 F-D easy to machine?
Reasonably — machinability is rated good (68/100, better than 67% of aluminum grades). Machines freely with sharp PCD or uncoated carbide tooling at high speed; the eutectic and primary Si are abrasive, so PCD is standard for high volumes, and porosity can be exposed in machined sealing faces.
Can EN AC-46000 F-D be welded?
Not readily — weldability is rated poor (25/100). Essentially not fusion weldable as a die casting — entrapped gas causes blowholes and the Cu content promotes hot cracking; use mechanical joining, adhesive bonding, self-pierce riveting or friction stir/laser only on high-integrity vacuum castings.
What surface finishes work on EN AC-46000 F-D?
Best finished by chromate-free conversion coating plus e-coat/powder paint; decorative anodizing is poor (dark grey), electroless nickel or zinc-based plating is used for wear/EMI, and shot blasting or vibratory finishing evens the as-cast skin.
Can EN AC-46000 F-D be formed, bent or molded?
Outstanding HPDC alloy: fluid at 660–700 °C melt / 200–240 °C die, tolerates 1 % Fe to resist die soldering, wall sections down to ~1.5 mm, and takes high recycled charge.
What is the maximum service temperature of EN AC-46000 F-D?
EN AC-46000 F-D is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between EN AC-46000 F-D and EN AC-46000-T6?
F-D is the default condition — default condition: thin-wall high-pressure die castings used as cast, no heat treatment. T6: only for low-gas castings (vacuum/high-integrity HPDC, squeeze or gravity cast) where maximum strength and hardness are required; conventional die castings blister. Yield strength is 155 MPa in F-D versus 240 MPa in T6.
