Facts

Interesting Facts

Aluminum’s abundance percentage is more as it is found in more than 260 minerals.

Pure Aluminum always reacts with oxygen rapidly.

It is a good conductor of heat and electricity and used in transmission lines.

It is found in copper ores and from the crust of the earth.

It is the most malleable and ductile metal.

Gold alloys are used in Dentistry as fillings, crowning, clips, etc. It is also used as an artificial limb joints.
