AZ91 Magnesium Alloy EDM Machining
We review AZ91 Magnesium Alloy for EDM machining based on your drawing and project requirements.
EDM Parameter Summary
| Parameter | Reference Range / Value |
|---|---|
| Material | AZ91 Magnesium Alloy |
| Typical Tolerance (Wire EDM) | ±0.005 – 0.025 mm |
| Typical Surface Finish | Ra 0.1 – 3.2 μm |
| Recast Layer Risk | High |
| Post-Process Recommendation | Polishing, lapping, chemical cleaning, passivation, stress relief or recast-layer removal for critical surfaces |
EDM Feasibility Notes
We review EDM feasibility for AZ91 Magnesium Alloy using the drawing geometry, conductive material condition, tolerance, surface finish, quantity and inspection requirements.
Material Behavior in EDM
We review AZ91 Magnesium Alloy according to material grade, conductivity, heat treatment condition, feature geometry, tolerance, surface finish and inspection requirements before confirming the EDM route.
Process Capability Facts
The selected EDM process suitability depends on drawing access, feature geometry, material conductivity, electrode or wire path, flushing conditions and the required inspection method.
Tolerance and Surface Finish Expectations
Typical tolerance and surface finish depend on material, thickness, feature geometry, flushing, finishing passes, machine setup and inspection method. Final values must be confirmed from the drawing.
Thickness and Geometry Review Notes
Review part thickness, feature depth, inside radii, cutting access and geometry stability before confirming the EDM route for AZ91 Magnesium Alloy.
Surface Integrity and Recast Layer Review
EDM can create a recast or white layer and other thermal surface effects. Critical surfaces should identify post-processing and inspection requirements on the drawing.
Inspection and Drawing Requirements
Please include material grade, drawing revision, critical dimensions, datums, tolerance, surface finish, quantity and any inspection report requirements. We confirm the inspection method according to the drawing before quotation. Please also include destination country, end-use information and any compliance requirements when additional review may be needed.
Sample Before Batch Production
Sample approval is recommended before batch production when tolerance, surface integrity, material response, geometry or documentation requirements must be confirmed.
Drawing Requirement Checklist
Send us your drawing, material grade, quantity, destination country and application notes so our team can confirm machining feasibility.
- drawing, material spec, destination, end use, certificate requirement, quantity, tolerance, surface integrity requirement
- Compliance/risk acknowledgement must be shown before submission.
- Drawing is strongly recommended for any quotation; required for tight tolerance, micro feature, cavity, export/compliance or batch production review.
Additional Project Review
Some materials, applications, or destination countries may require additional review before quotation. Send us your drawing, material grade, quantity, destination country, and application notes so our team can confirm machining feasibility.
