Aluminum
A356 Casting Alloy
A356 denotes an Al-Si-Mg casting alloy family; the reviewed Belmont product is A356.2 feedstock.
Identity / state reference
What distinguishes this material
A356.2 ingot properties and a completed A356.0 casting are different evidence objects.
- Designation in this reference
- A356 casting alloy
- Forms covered by the sources
- Foundry ingot reference
- Finished casting requires separate evidence
- States to distinguish or confirm
- T6 is a possible heat-treatment route
- not proved for a supplied casting
- Temperature and exposure
- No general service-temperature limit or temperature-independent strength is established by this page. Check the temperature and duration for the specific source table and application.

Property evidence for a stated condition
No condition-specific numerical table is reproduced here
The linked sources establish the identity and the stated product/state scope. Obtain the row for your actual form, section, treatment and test conditions before adopting strength, hardness or a thermal limit.
Resolve these conditions next
- Is the item ingot or a casting, what mould/process was used, and is its actual temper verified?
- Obtain the full material certificate, governing specification/edition, product dimensions and test direction before adopting a property value.
For machining, take the exact grade, supplied condition and measured hardness where applicable into the tool maker’s application data. A generic material-family speed is not a substitute for an operation and tool-specific recommendation.

Belmont Metals — A356.2 aluminum alloy
Producer ingot product A356.2, Al-Si-Mg identity and heat-treatment route; not finished A356.0 casting test data.
Belmont Metals — A356.2 aluminum alloy ↗Source identity, a named product example and a supplied-batch certificate are different evidence. Cross-standard similarity does not approve substitution.
Corrections from the previous article
- Remove the unqualified 275 MPa/70 HB T6 result and any inference that ingot chemistry guarantees finished casting strength.
- Remove the untraceable generic machining recommendation (200 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.
