Magnesium Oxide: Benefits, Side Effects, Dosage, and

Magnesium oxide is acquired by burning magnesium with pure oxygen, but this method is quite costly. The cheaper method is to expose oxygen to magnesium salts using underground deposits, seawater, or salt beds. With this method, the source of the magnesium salt determines the quality of the magnesium oxide that is produced.

Ultralight Magnesium – American Carbon Company

Magnesium is one of the fastest growing specified structural metals. The reasons are simple. Magnesium is 30% lighter than aluminum and has nearly identical strength to weight ratio. Couple that with the advances in alloying that have developed over the years and there are very few disadvantages to using magnesium.
