A student compares the composition of two different magnesium alloys to see how their properties differ.
| Element | Percentage of element in magnesium alloy with low tensile strength (%) | Percentage of element in magnesium alloy with high tensile strength (%) |
|---|---|---|
| Magnesium | 98.7 | 90.2 |
| Zinc | 1.0 | 0.8 |
| Aluminium | 0.0 | 8.5 |
| Manganese | 0.3 | 0.5 |
Using the table, state which metal is added to magnesium to increase its tensile strength.
