- Fabrication flexibility: suitable for ship structures, marine components and customized plate fabrication.
Chemical Composition of 5086 Aluminum
5086 is an aluminum-magnesium alloy with manganese and chromium additions. Magnesium is the principal alloying element and contributes to strength and corrosion resistance. Actual chemical composition should be confirmed according to the applicable specification and material certificate.
| Element | Mg | Mn | Cr | Fe | Si | Cu | Zn | Al |
|---|---|---|---|---|---|---|---|---|
| 5086 | 3.5-4.5% | 0.20-0.70% | 0.05-0.25% | ≤0.50% | ≤0.40% | ≤0.10% | ≤0.25% | Balance |
Mechanical Properties of 5086-H116 Plate
Mechanical requirements for 5086-H116 plate vary with product thickness and the applicable specification. Tensile strength, yield strength and elongation should therefore be verified against the ordered thickness and ASTM B928/B928M requirements.
| Property | Supply Consideration |
|---|---|
| Tensile Strength | According to ASTM B928/B928M and ordered thickness |
| Yield Strength | According to H116 temper and thickness requirements |
| Elongation | Depends on thickness and applicable test requirements |
| Temper | H116 Marine Service Condition |
