MATERIAL
OVERVIEW
Characteristics:
Silvery, moderately hard alkaline-earth metal, readily
fabricated by all standard methods. Lightest of the
structural metals. Strong reducing agent. Electrical
conductivity similar to aluminum. Soluble in acids,
insoluble in water. Magnesium is the central element
of the chlorophyll molecule and is also an important
component of red blood corpuscles.
Hazards:
Combustible at 650 oC
(solid metal). Flammable, dangerous fire hazard
(powder, flakes, etc.). Use dry sand or talc to
extinguish.
