Correct Answer

A. Al + Mg

About Magnalium

This alloy is known for its lightweight and strong properties, making it useful in various applications, including aerospace and automotive industries.

Other Alloy Compositions

• Al + Cu + Mg + Mn: This combination is typically used for different aluminum alloys, not magnalium.
• Al + Zn + Mg + Ni: This is another type of aluminum alloy, but not magnalium.
• Al + Cu: This is a common alloy but lacks magnesium, which is essential for magnalium.

In summary, magnalium is specifically defined by its aluminum and magnesium content.
