“Magnesium protection gas requires a multi-channel mixer used in supplying other protection gases that vary in terms of optimal concentration and flow depending on production process (dissolution, casting & refrigeration).
A shielding gas mixer applied to a die casting process where magnesium melt is injected into a mold in a closed crucible fills only the empty space of the crucible with the protection gas, but a shielding gas mixer for board production needs to keep supplying ambient gas to prevent contact with oxygen even in a closed crucible and a casting process (open process).

Properties of magnesium

Magnesium, 12Mg
Chemical Symbol, Origin
Originated from Magnesia, a provincial city in Thessaly in the east of Greece where magnesium ore was mined
Distribution
It is the world’s 8th commonest element (9th in the universe) that accounts for 2 percent of the weight of the Earth’s crust and exists within 60 kinds of minerals. One liter of seawater contains 1.29g of Mg2+ (12% of Na+).
Standard atomic weight	24.305
Detector	Humphry Davy (1808)
Status (Room temperature, 1 Atmosphere)	Silver white solid matter
Density (20°C, 1 Atmosphere)	1.738g/cm3
Melting point (1 Atmosphere)	650°C
Boiling point (1 Atmosphere)	1.090°C
Main isotopes	24Mg (78.99%), 25Mg (10.00%), 26Mg (11.01%)

Main uses
It is an essential element in many enzymes and chlorophyll and used in manufacturing light-weight alloys applied to automobiles, aircraft, and electronics as well as sacrificial anodes, fireworks and firebombs. Compounds are used as refractories, food additives, laxatives and antacids for various purposes.
