Starting cutting speed in m/min and sfm, feed in mm/rev and ipr, the carbide grade class and the setup by operation for EN AC-46000. The numbers are the published N10 Aluminium alloys (cast) sub-group starting band; the designations are on the cross-reference page.

Hardness is the range published for the whole N10 Aluminium alloys (cast) sub-group on our material guide; the delivery condition of your EN AC-46000 may sit anywhere inside it or outside it.
At least one designation of this material is a nearest commonly-cited counterpart, not a same-composition equivalent. The machining values below belong to the sub-group, so confirm the actual alloy and delivery condition on the material certificate.
| Condition | Vc m/min | Vc sfm | Feed mm/rev | Feed ipr |
|---|---|---|---|---|
| N10 Aluminium alloys (cast), 75–130 HB | 200–800 | 655–2625 | 0.05–0.30 | .002–.012 |
Sub-group starting values for carbide inserts, from N10 Aluminium alloys (cast). They describe the whole sub-group and are not tuned to EN AC-46000. sfm and ipr are converted from the metric values (1 m/min = 3.281 sfm, 25.4 mm = 1 in). The published band is per sub-group, not per operation; the table below gives the setup by operation. Convert Vc to spindle speed with the speeds & feeds calculator, and see the speeds & feeds guide for the ISO N group range.
| Operation | Geometry | Coating family | Coolant | First check |
|---|---|---|---|---|
| Roughing | Sharp, high positive rake, polished flute; good chip evacuation | PCD for high-silicon alloys and long runs; polished uncoated or DLC carbide otherwise | Coolant or MQL | Abrasive silicon wear: move to PCD for life |
| Finishing | Sharp, high positive rake, polished flute | PCD or polished uncoated / DLC carbide | Coolant or MQL | Built-up edge or smear: raise feed, flush chips |
| Interrupted cut | Sharp positive edge, open chipbreaker | PCD or polished carbide | Coolant or MQL | Chip evacuation in cavities |
| Low rigidity / thin wall | Keen positive edge, polished flute | Polished uncoated or DLC carbide | Coolant or MQL | Poor finish at high RPM: raise feed per tooth, not just speed |
Setup rows are the selection table of the N10 Aluminium alloys (cast) guide. They carry no speeds, so they do not change the starting band above.
PCD for high-silicon cast alloys (A356, ADC12) and long runs; polished uncoated or DLC carbide for low-silicon or short runs.
The P, M, K, N, S or H number inside a grade range describes what the grade is built for, not the workpiece sub-group number, and the two scales must not be matched to each other. We name no single grade here: none of our published sources ties a named grade to this alloy. Pick by ISO class, then compare what the makers publish on the ISO N grade list and in the grade chart.
EN AC-46000 (AlSi9Cu3(Fe)), US A380 (nearest), JIS ADC10 (nearest). The full table, with the nearest-match flags, is on the EN AC-46000 / A380 cross-reference page.
The high-volume die-casting alloy: silicon makes it abrasive, so PCD or sharp uncoated carbide earns its keep. Cast skin and porosity decide the first pass.

The published starting band for the N10 Aluminium alloys (cast) sub-group is 200–800 m/min (655–2625 sfm) at 0.05–0.30 mm/rev (.002–.012 ipr). It is a starting band for the whole sub-group, not a value tuned to EN AC-46000, so confirm on a sample part and adjust for condition, tool and rigidity.
PCD for high-silicon cast alloys (A356, ADC12) and long runs; polished uncoated or DLC carbide for low-silicon or short runs. Pick the grade by ISO class rather than by brand name, then confirm the exact grade for your condition. We name no single grade here because none of our published sources ties a named grade to this alloy.
EN AC-46000 (AlSi9Cu3(Fe)) (no Werkstoffnummer listed); US: A380 (nearest); JIS: ADC10 (nearest). At least one pairing is nearest-by-properties, not a drop-in equivalent: the material certificate decides.
The advisor compares what the makers publish for your material and operation and shows the source behind each answer, or tells you it could not verify.
