Aluminium Alloy Selection for Pressure Die Casting
Metalcraft Industries supports aluminium alloy selection for pressure die casting requirements, helping customers choose suitable material grades based on application, strength, corrosion resistance, machinability, finish, and production needs.
Choosing the Right Aluminium Alloy for Your Component
Aluminium alloy selection plays an important role in the performance, manufacturability, corrosion resistance, machinability, and finish of a die-cast component. Metalcraft Industries works with commonly used aluminium die casting alloys and supports customers in selecting a suitable alloy based on actual production and application requirements.
The best alloy depends on factors such as component geometry, end use, required strength, pressure tightness, corrosion conditions, finishing needs, and downstream machining. This selection is often reviewed during the die design and development phase.
Our role is not just to supply material — it is to help align alloy choice with the real manufacturing and application needs of the component for successful high pressure die casting production. Explore our full range of capabilities.
What Our Alloy Support Includes
Alloy Guidance Based on Application
We help review alloy suitability based on the component's end use, mechanical needs, corrosion conditions, and finishing requirements.
Support for Common Die Casting Alloys
We work with established aluminium die casting grades used across industrial, electrical, automotive, lighting, and general engineering applications.
Material Traceability Support
Where required, alloy selection can be supported with material documentation and traceability from approved sources.
Alloy Selection Linked to Production Feasibility
We consider not only the application, but also manufacturability, die casting suitability, machining needs, and repeat production requirements.
Aluminium Alloys We Commonly Work With
The alloys below are commonly used for aluminium pressure die casting. Final suitability depends on the specific component requirement, application, machining needs, and finish expectations.
| Alloy | Standard | Typical Characteristics | Typical Uses |
|---|---|---|---|
| ADC12 | JIS H5302 | Good castability, good fluidity, good machinability, widely used for general die-cast components. | Housings, covers, brackets, enclosures, and general engineering components. |
| A380 | ASTM B85 | Good combination of strength, castability, corrosion resistance, and thermal performance. | Electrical enclosures, lighting parts, heat-related components, industrial housings, and general aluminium die-cast parts. |
| LM6 | BS 1490 | High corrosion resistance, good ductility, good pressure tightness, suitable for applications needing corrosion performance. | Pump-related components, valve-related parts, marine or exposed-use applications, and corrosion-sensitive components. |
| LM24 | BS 1490 | Good pressure tightness, good strength, strong casting performance, suitable for many engineering applications. | Housings, industrial parts, pressure-sensitive castings, and repeatable custom components. |
Other alloys may be reviewed based on customer specifications, application requirements, and production feasibility.
How the Right Alloy Is Selected
Choosing the right aluminium alloy usually depends on a combination of application, performance, and manufacturing factors.
No single alloy is "best" for every requirement. The right choice depends on what the component needs to do and how it needs to be manufactured.
When to Ask for Alloy Selection Support
Buyers should ideally ask for alloy guidance when:
What to Share for Alloy Recommendation
To recommend a suitable aluminium alloy, our team may review the following information.
If all details are not yet available, we can still provide preliminary guidance based on the information currently known.
Why Alloy Choice Matters to Manufacturing
Alloy selection does not only affect the final performance of the component — it also affects casting behavior, machining response, finish quality, and repeat production stability. Choosing the right alloy helps align the component's design intent with practical manufacturing outcomes.
Alloy Selection Linked to Die Casting, Tooling, and Production
At Metalcraft Industries, alloy selection is linked to the broader manufacturing process. Our team reviews alloy choice in relation to die casting suitability, tooling approach, machining needs, and the long-term production requirements of the component.
This helps customers get material advice that is practical, production-oriented, and aligned with actual manufacturing conditions.
Frequently Asked Questions
Which aluminium alloys does Metalcraft commonly work with?
Metalcraft commonly works with aluminium die casting alloys such as ADC12, A380, LM6, and LM24, depending on component requirements and application needs.
Can Metalcraft help recommend the right alloy for a component?
Yes. We can review the component application, performance needs, machining requirements, and finish expectations to suggest a practical alloy option.
Is alloy selection important before tooling and production?
Yes. Alloy choice can affect castability, machining, corrosion resistance, pressure tightness, finish, and overall production suitability.
What information is needed to review alloy suitability?
Ideally, buyers should share the drawing, application, performance expectations, exposure conditions, machining needs, and finish requirements.
Can other alloys be discussed if the requirement is outside the standard range?
Yes. Other alloys can be reviewed depending on customer specifications, application requirements, and production feasibility.
