A non-heat-treatable magnesium alloy referenced for marine sheet and plate. Exact temper, section and service requirements govern acceptance.
Selected indicative supplier facts; critical specification values require independent confirmation. Keep typical values, source minima and composition limits distinct. Reference records are not certificates or design allowables.

Reviewed temper examples: O, H111. These do not establish every possible alloy-form-temper supply combination.
Physical properties
Numerical physical properties are not verified for this record and remain withheld.
| Temper | Product form | Thickness / specimen condition | Tensile MPa | Yield MPa | Basis | Source ID |
|---|---|---|---|---|---|---|
| O / H111 | Sheet | 0.2–6.3 mm; BS EN 485-2:2008 cited by supplier | 275–350 | 125 | indicative-range | aalco5083 |
O / H111 / Sheet: Supplier cites historic EN edition; not an authorized standard table or certification; checked 2026-10-14.
Chemical composition
Composition coverage remains pending source review.
Fabrication and material selection
The supplier density field is malformed and remains withheld. Marine selection must consider the approved material specification and fabricated condition; the alloy name alone does not establish vessel qualification.
Applications and product forms
Confirm the end-use requirements against the supplied material and governing specification.
Standards and acceptance
Identify the governing product specification by the actual form and manufacturing route. A grade designation alone does not establish compliance or equivalence. Confirm the edition, required condition, inspection and dimensional limits through the supplier and an authorized specification.

Technical questions
Are typical values delivery limits?
No. A typical reference value describes the source condition; it is not a guaranteed minimum for a delivered lot.
Which temper and thickness should I compare?
Compare the same material form, temper, thickness/test condition, unit and value basis. Different conditions cannot be silently treated as interchangeable.
Technical sources and verification
Selected reference facts checked 14 October 2026. Source values apply to their stated material condition and are not certification of supplied stock.
