Aluminum and zinc die casting both support custom metal components, but they solve different problems. Buyers should compare size, weight, detail, surface finish and assembly requirements before choosing.
A larger housing may benefit from aluminum weight savings, while a small connector or threaded fitting may benefit from zinc alloy detail and surface quality.
| Decision point | Aluminum die casting | Zinc die casting | Buyer action |
|---|---|---|---|
| Best fit | larger housings, brackets, heat sinks and machinery parts | small precision parts, connectors, caps and hardware | choose by function, not only material price |
| Manufacturing risk | thin fins, thick bosses and porosity need DFM review | threads and plating thickness need control | review surface treatment and assembly features |
| Cost driver | tooling, machining and finishing drive total cost | small part complexity and surface treatment drive cost | compare total process scope |
| Inspection focus | flatness, holes, coating and casting defects | threads, burrs, plating and small features | define final inspection after finishing |
Huabo usually reviews aluminum and zinc projects separately because mold design, trimming, machining and finishing risks are different.
A zinc part may look more expensive by weight but save machining on small detailed parts. An aluminum part may reduce weight but need more machining on functional surfaces.
Provide part size, weight target, threads, surface finish, mating components and annual quantity.
Related reference: custom zinc alloy die casting parts, zinc die casting service and electrical appliance die casting parts.
Zinc is heavier, but it can cast fine details and small features with less secondary machining. Aluminum is lighter, but thin ribs, large flat faces and heat paths need more DFM attention. A fair cost comparison should include mold complexity, trimming, CNC machining, surface treatment and inspection, not only raw material cost per kilogram.
| Part feature | Often favors | Reason |
|---|---|---|
| Small threaded connector | Zinc die casting | Detail and surface quality can reduce machining. |
| Large heat-dissipating cover | Aluminum die casting | Weight and thermal function matter more. |
| Decorative visible hardware | Zinc die casting | Plating and fine surface detail are common requirements. |
Send the same drawing and surface standard to both material routes if you are comparing them. Otherwise one supplier may quote a raw casting while another includes machining, plating and inspection, making the comparison misleading.
