How should buyers choose between A380 and ADC12 aluminum die casting?
Buyers should choose between A380 aluminum die casting and ADC12 or 383 aluminum die casting by comparing part geometry, castability, mechanical requirements, machining scope, surface finish, inspection needs, and production economics. The practical RFQ problem is to decide which aluminum die casting alloy supports the custom part's wall thickness, ribs, bosses, functional faces, cosmetic surfaces, and volume before tooling is quoted.
What is the practical difference between A380 and ADC12?
A380 and ADC12/383 are both common aluminum die casting alloys, but buyers usually review them for slightly different production priorities. A380 is often considered for balanced general-purpose die casting parts, while ADC12/383 is often reviewed when filling behavior and production practicality are important for complex geometry.
The alloy decision should not be made only from a material name. A housing, bracket, cover, heat sink base, or machined die cast component may require different emphasis on castability, strength, corrosion behavior, surface finish, machining, and inspection.
Decision Factor | A380 Aluminum Die Casting | ADC12/383 Aluminum Die Casting |
|---|---|---|
Common selection role | Balanced alloy for many housings, covers, brackets, and OEM components | Common alloy route for feature-rich and production-oriented die cast parts |
Geometry review | Useful when the part needs a broad balance of properties and manufacturability | Often reviewed when thin walls, ribs, and complex features drive fill behavior |
Machining planning | May be paired with CNC finishing for datums, bores, holes, and sealing faces | May also need CNC finishing when critical fit or threads are required |
Finish planning | Requires review of cosmetic surfaces, coating, and surface preparation | Requires review of cosmetic surfaces, coating, and surface preparation |
Buyer decision | Choose when balanced part requirements drive the material route | Choose when production filling behavior and geometry practicality are key priorities |
When should buyers consider A380 aluminum die casting?
Buyers should consider A380 aluminum die casting when the part needs a balanced material for general structural, housing, cover, bracket, frame, or industrial component applications. A380 is often a practical starting point when the design does not require a specialized corrosion, wear, or strength-driven alloy decision.
The buyer should still define the application, surface finish, machined features, and inspection requirements. A380 can support many common die cast parts, but the final cost and quality still depend on tooling design, wall thickness, gating, venting, CNC machining, finishing, and release inspection.

When should buyers consider ADC12 or 383 aluminum die casting?
Buyers should consider ADC12 or 383 aluminum die casting when the part has complex geometry, thin wall sections, ribs, bosses, detailed cavities, or production requirements where filling behavior matters. ADC12/383 is often discussed for OEM parts that need practical casting behavior in repeated production.
ADC12/383 is not a shortcut around design review. Buyers still need to provide wall thickness, draft, critical dimensions, visible surfaces, and post-processing requirements. If the part has tight-fit holes, threads, datums, sealing faces, or thermal contact surfaces, CNC machining and inspection may still be required.
How do geometry, machining, finishing, and inspection affect the choice?
Geometry, machining, finishing, and inspection can be more important than the alloy name alone. Thin walls and feature-rich geometry may influence castability. Machined bores, threaded holes, and flat datums may influence post-casting CNC scope. Painting, powder coating, anodizing when suitable, or conversion coating can influence surface preparation and inspection.
Buyers should identify which surfaces are as-cast, machined, coated, masked, visible, or functional. If the RFQ only asks for A380 or ADC12 without defining these features, Neway may not have enough information to quote the finished part accurately.
Buyer Requirement | Why It Affects A380 vs ADC12 Review | RFQ Detail to Provide |
|---|---|---|
Thin walls and ribs | Influence mold filling, shrinkage, and defect risk | 3D CAD, wall thickness, rib height, and feature priority |
Machined features | Influence CNC scope, tolerance, and inspection cost | Thread list, bores, datums, sealing faces, and CMM needs |
Surface finish | Influence surface preparation, masking, coating, and cosmetic acceptance | Finish type, visible zones, color, texture, and defect criteria |
Production volume | Influence tooling design, cavity planning, and cost assumptions | First order quantity, annual demand, and production life |
Inspection evidence | Influence release plan and quality documentation | Critical dimensions, sampling plan, test method, and report requirements |

What RFQ information helps Neway choose between A380 and ADC12?
Neway can help choose between A380 and ADC12/383 more accurately when the RFQ includes 3D CAD, 2D drawing, part application, annual volume, wall thickness, surface finish, machined features, critical dimensions, corrosion exposure, inspection method, and any buyer preference for A380 or ADC12.
The buyer should state the decision priority directly. If the priority is balanced part performance, A380 may be reviewed first. If the priority is complex geometry and filling practicality, ADC12/383 may be reviewed first. If the priority is corrosion, strength, wear, or another performance need, Neway may review additional aluminum die casting alloys.
