Magnesium Die casting
Magnesium Die casting, Magnesium was one of the main aerospace construction metals. Due to perceived hazards with magnesium parts in the event of fire.The application of magnesium die casting in the commercial aerospace industry was generally restricted to engine related components. Currently the use of magnesium alloys in aerospace is increasing. The development and testing of new magnesium alloys continues.The European Community runs three R&D. magnesium projects in the Aerospace priority of Six Framework Program. where recently has magnesium been used in Magnesium Die casting by die casting companies.
Magnesium is flammable burning at a temperature of approximately 2500 K. The auto ignition temperature of magnesium is approximately 744 K in air. The extremely high temperature at which magnesium burns makes it a handy tool. Other related uses include flashlight photography, flares, pyrotechnics, fireworks sparklers, and incendiary bombs.
Magnesium Die casting metal and its alloys are explosive hazards. They are highly flammable in their pure form when molten or in powder or in ribbon form. Burning or molten magnesium metal reacts violently with water. When working with powdered magnesium, safety glasses with welding eye protection are employed.because the bright white light produced by burning magnesium contains ultraviolet light that can permanently damage the retinas of the eyes.

What is Magnesium?
The lightest structural material (1.8g/cm3), magnesium is the 8th most abundant element in the earth’s crust. It occurs naturally in Dolomite, Magnesite, Carnallite and Chloride (sea water).
Where is it found?
Magnesium is produced from sea water, brines and magnesium-bearing minerals which offer unlimited reserves.
How much magnesium is produced?
350,000 metric tons in 1990; 2005 estimated at 500,000 metric tons.
What are the major benefits of magnesium?
Lightest of all structural materials
75% lighter than steel
33% lighter than aluminum
High impact resistance
High strength to weight ratio
Can be cast to net shape
Excellent dimensional stability/repeatability
Abundant material supply
Hot-Chamber Die Casting
Chicago White Metal uses hot-chamber die casting to produce die cast magnesium parts. In this process, the metal injection components are submerged in a reservoir of molten magnesium. A hydraulically-powered piston forces the magnesium into the die, taking advantage of magnesium’s excellent flow characteristics to accurately produce complex shapes.
