- Lightest structural metal (~1.8 g/cm³)
- Excellent machinability
- High strength-to-weight
- Damping capacity
Machining AZ91D Magnesium with CNC Sinker EDM
When EDM machining AZ91D Magnesium, machinability is excellent (fastest of structural metals); fire-safe chip handling required. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for AZ91D Magnesium mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Sinker EDM AZ91D Magnesium
| Feature | Standard | Precision |
|---|---|---|
| Profile dimension | ±0.010 mm | ±0.002 mm |
| Internal corner radius | 0.15 mm | 0.05 mm |
| Taper control over 50 mm | 0.02 mm | 0.005 mm |
| Surface finish (skim passes) | Ra 0.8 µm | Ra 0.2 µm |
| Recast layer | 10 µm | 2 µm (fine skim) |
| Start-hole diameter | 1.0 mm | 0.25 mm |
| Workpiece hardness | no limit (conductive) | no limit (conductive) |
Standard is what a normal quotation assumes. Precision is available on nominated features and is priced separately, because it needs extra setups, in-process gauging and CMM verification. Call out only the features that need it — blanket-tightening a drawing is the single most common reason a quote comes back expensive.
Secondary Operations & Finishing
Most AZ91D Magnesium parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
Why AZ91D Magnesium?
Customers select AZ91D Magnesium for CNC Sinker EDM because it is ultralight with excellent machinability. We handle grade verification and any required heat treatment or finishing.
CNC Sinker EDM Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
Design Tips for CNC Sinker EDM AZ91D Magnesium
Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened AZ91D Magnesium that cannot be milled; allowing a small corner radius where possible speeds the cut. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Sinker EDM Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the AZ91D Magnesium part, producing fine, controlled surface textures and sharp internal corners impossible to mill.
Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.
Applications of CNC Sinker EDM AZ91D Magnesium
AZ91D Magnesium parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

What We Need to Quote CNC Sinker EDM AZ91D Magnesium
- GeometrySTEP or IGES for the 3D model, plus a PDF drawing if you have tolerance callouts. A dimensioned sketch is enough to start.
- MaterialThe exact AZ91D Magnesium grade and condition — temper, heat-treat state or hardness. If you are not sure, tell us the function and we will suggest one.
- QuantityPrototype count and the expected annual volume. Both change how the part is made and therefore what it costs.
- TolerancesWhich features are critical. Everything else runs to our standard tolerance, which is what keeps the price sensible.
- FinishSurface treatment, cosmetic requirements, and any faces that must be masked.
- DocumentsWhether you need a material certificate, dimensional report, FAIR or PPAP with the shipment.
Missing something from the list is not a problem — send what you have. We will come back with the specific questions rather than a generic form.

Request a QuoteFrequently Asked Questions
What material thickness or size range suits CNC Sinker EDM AZ91D Magnesium?
We machine AZ91D Magnesium across a broad size range; share your part envelope for confirmation.
Does CNC Sinker EDM AZ91D Magnesium require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
Can you EDM-machine hardened AZ91D Magnesium?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult AZ91D Magnesium can be machined to fine detail and tight tolerance without distortion.
What is the typical lead time and minimum order for CNC Sinker EDM AZ91D Magnesium?
CNC Sinker EDM prototypes for AZ91D Magnesium can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
