Mg(pellets & pieces)

Magnesium is a grey-white, alkaline earth metal with a melting point of 649°C, a density of 1.74 g/cc, and a vapor pressure of 10-4 Torr at 327°C. It is extremely flammable, especially in powder form, and fires are difficult to extinguish. Magnesium is also an essential element to life. Magnesium is responsible for regulating nerve function, blood pressure, and the levels of nutrients in the human body. It is extensively used in the production of aircraft, engine casings, laptops, cell phones, and cameras. Magnesium and its alloys are evaporated under vacuum for the development of magnetic storage media, optical storage media, and semiconductors.
