Can the body eliminate aluminum?

Approximately 95% of an aluminum load becomes bound to transferrin and albumin intravascularly and is then eliminated renally. In healthy subjects, only 0.3% of orally administered aluminum is absorbed via the gastrointestinal (GI) tract, and the kidneys effectively eliminate aluminum from the human body.

Good heat and electrical conductor.

What are the importance of Aluminium why it is popular?

Aluminium is a widely popular metal due to the vast variety of uses that this malleable metal can be used for. Particularly its high strength and low weight, and it is corrosion resistant as the grey oxide-layer provides protection. The corrosion resistance can be further reinforced if hard-anodised.

Why is Aluminium used in aircraft?

Aluminum is ideal for aircraft manufacture because it’s lightweight and strong. Aluminum is roughly a third the weight of steel, allowing an aircraft to carry more weight and or become more fuel efficient. Furthermore, aluminum’s high resistance to corrosion ensures the safety of the aircraft and its passengers.
