Custom Magnesium Forging Products
Forged Magnesium Blocks and Blanks
Forged stock for subsequent CNC machining, structural components, tooling, supports, and other applications that benefit from controlled material flow and improved integrity. Blanks can be supplied as-forged, saw-cut, heat-treated, or rough-machined.
Closed-Die Magnesium Forgings
Custom near-net-shape forgings for repeatable production. Closed-die forging can reduce material removal and create a part geometry closer to the final component, subject to draft, parting-line, material-flow, and tooling requirements.
Open-Die Magnesium Forgings
Open-die options for simple shapes, blocks, discs, rings, shafts, and low-volume or larger preforms. Final feasibility depends on alloy, dimensions, press capacity, and required mechanical properties.
Forged and CNC-Machined Parts
Forging followed by milling, turning, drilling, tapping, deburring, inspection, and surface finishing. This route is suitable when the final component requires precision mounting faces, bores, threads, sealing surfaces, or assembly interfaces.
Magnesium Alloys for Forging
The correct alloy should be selected from the part function, forging route, service temperature, strength and fatigue requirements, corrosion strategy, machining plan, and specification—not from alloy popularity alone.
| Alloy | Selection Direction | Typical Product Direction |
|---|---|---|
| AZ31B | Practical wrought alloy with good workability and machinability | General forgings, machined structural parts, brackets, and lightweight components |
| AZ61A | Balance of strength, workability, and availability | Industrial and structural forgings |
| AZ80A | Higher-strength wrought-alloy direction | Load-bearing and performance-oriented forgings |
| ZK60A | High specific strength and fatigue-performance direction | High-performance structural components |
| WE43 | Elevated-temperature and demanding performance direction | Aerospace, motorsport, and high-requirement components |
Important: Alloy availability, specification, temper, minimum order, and achievable properties must be confirmed for each project.
Open-Die vs. Closed-Die Magnesium Forging
| Factor | Open-Die Forging | Closed-Die Forging |
|---|---|---|
| Best suited for | Simple shapes, blanks, lower volumes, and larger preforms | Repeatable near-net-shape components and stable production designs |
| Tooling | Lower tooling complexity in many cases | Dedicated dies normally required |
| Geometry | Less complex | More detailed, subject to forging design rules |
| Machining | Usually requires more material removal | Can reduce post-forge material removal |
| Volume | Prototype and lower-volume directions | More attractive for repeat production |
Forging + CNC Machining from One Supply Chain
Most magnesium forgings still require machining of functional features. Miji can supply a forged blank or coordinate post-forge CNC machining according to the final drawing and inspection plan.
- CNC milling and turning
- Drilling, boring, reaming, and tapping
- Datum and mounting-surface machining
- Critical-hole and interface finishing
- Deburring, cleaning, and surface preparation
- Dimensional inspection and project-specific reports
For detailed machining information, see our magnesium alloy CNC machining capabilities.
From Drawing to Finished Magnesium Forging
- Drawing and application review: We review geometry, alloy, load direction, critical properties, quantity, specification, and delivery condition.
- Alloy and process selection: The proposed route is matched to the product form, service environment, forging method, heat treatment, and machining plan.
- DFM and feasibility review: Material flow, draft, parting line, radii, machining allowance, distortion risk, and inspection access are evaluated.
- Tooling and preform planning: Tooling scope and starting-stock geometry are defined when custom dies are required.
- Controlled-temperature forging: Material preparation, heating, deformation, and trimming are managed according to the approved route.
- Heat treatment and secondary processing: Heat treatment, shot blasting, straightening, or other required operations are completed as specified.
- CNC machining: Critical surfaces, holes, threads, and interfaces are machined to the drawing.
- Inspection and delivery: Required documents are reviewed before protective packaging and export delivery.

Frequently Asked Questions
Which magnesium alloys can be forged?
Common forging directions include AZ31B, AZ61A, AZ80A, ZK60A, and selected WE-series alloys. The suitable grade depends on part function, forging route, service temperature, required properties, specification, and availability.
Do magnesium forgings still require CNC machining?
Often, yes. Forging can create a strong preform or near-net shape, while CNC machining is normally used for precision holes, threads, mounting faces, sealing surfaces, datums, and final assembly interfaces.
Can you supply forged blanks instead of finished parts?
Yes, projects may be reviewed for as-forged, heat-treated, saw-cut, rough-machined, or fully machined delivery. The appropriate condition should be stated during quotation.
What information is required for a magnesium forging quote?
Please provide a STEP file and PDF drawing together with alloy, specification, dimensions, quantity, required properties, heat treatment, machining scope, inspection requirements, and delivery destination.
What inspection documents are available?
Available documents may include material certificates, dimensional reports, FAI, CMM reports, mechanical-property reports, and NDT records. The required inspection package must be confirmed before quotation.
How long does custom magnesium forging take?
Lead time depends on material availability, tooling, forging complexity, heat treatment, machining, inspection, and order quantity. Submit the drawing and target schedule for a project-specific estimate.
