What Are Some Lightweight Metals?

Are You Wondering What Some Of The Most Lightweight Metals Are?

Many people consistantly ask the question “What are some lightweight metals?” so we are here to provide you with an easily accesible list.

A List Of Lightweight Metals:

  • Aluminum
  • Aluminum Alloy
  • Magnesium
  • Magnesium Alloy
  • Titanium
  • Titanium Alloy
  • Beryllium

The low mass to volume ratio is what causes these metals to weigh less than other heavier metals.

Other metals such as copper, silver, gold, etc, have a higher mass to volume ratio. Therefore, when comparing two different metals with the same volume, one is heavier due to having more mass per volume.

For example.

A metal that weights 20 kg per 10 cubic centimeters is twice as massive as a metal that weighs 10kg per 10 cubic centimeter.


Q: At a metal recycling center, if you compare the weight of a full aluminum recycling bin to the weight of a full copper recycling bin, which one will weigh more?

A: Due to the fact that the aluminum is less dense and has a lower mass to volume ratio, the copper bin will weight much more than the aluminum bin if they are both filled up the same amount.
