Short answer: Choose magnesium when mass, specific strength, and damping matter more than absolute corrosion robustness and piece-price; choose алюминий when you need broader process windows, familiar supply chains, and typically lower melt-handling risk. Many programs stay aluminum; magnesium wins when the weight budget is real.
MINDWELL die-casts both (also zinc), with magnesium as a focus, in-house molds, and HPDC capacity up to 1600T (LK).

Process
Both alloys are commonly produced by high-pressure die casting. Differences show up in melt handling, die thermal design, and secondary finishing—not in “whether HPDC exists.”
MINDWELL path: DFM → in-house tooling → HPDC → FANUC CNC as needed → outsourced surface treatment / painting (baking finish) per RFQ.
Material
| Factor | Magnesium (typical HPDC view) | Aluminum (typical HPDC view) |
|---|---|---|
| Density | Lower → better for weight targets | Higher than Mg; still “light metal” |
| Specific strength | Often attractive for brackets/housings | Strong all-rounder |
| Corrosion | Needs design + finish attention | Generally more forgiving as-cast / coated |
| Process familiarity | Narrower supplier base | Very common |
| MINDWELL | Focus alloy family; AZ91D, AM50A, AM60B (final grade per drawing) | Fully in scope; grades per RFQ |
Commonly offered magnesium alloys: AZ91D, AM50A, AM60B (final grade confirmed per drawing / RFQ). Aluminum grades, mold steel, and coating specs remain per RFQ—not published as a stock catalog on this page.
Приложения
- Lean Mg: handheld housings, mobility brackets, weight-critical covers.
- Lean Al: structural housings, heat-sink class parts, high-volume covers.
- Wrong pattern: copying an Al wall scheme 1:1 into Mg without DFM.

Why MINDWELL
- Decision framework first—sales pitch second.
- Honest: we cast both; Mg is focus, not the only answer.
- Same tooling + press context for either path.
FAQ
Q: Is magnesium always lighter in the final assembly?
A: Usually lower density helps, but thick walls, inserts, and coatings can erase the gain—DFM required.
Q: Is magnesium always more expensive?
A: Piece and tooling economics vary with volume and yield; quote both paths when weight is a KPI.
Q: Can one mold run both alloys?
A: Rarely practical without major rework—plan alloy early.
Q: Do you cast Mg in Xiamen?
A: Yes — magnesium-alloys.
Q: Lead time?
A: Lead time quoted after DFM; we do not publish fixed week counts.
