Magnesium (Mg) Metal

Magnesium (Mg) is a light, moderately hard, silvery-white metal that ignites easily in the air and burns with a bright light. It is strong, has good heat dissipation and dampening, and is easy to weld, forge, cast or machine. It can improve the mechanical, fabrication, and welding characteristics when used as an alloying agent since it has a low density and is the lightest structural metal (a third lighter than aluminum). It also has good electrical properties.
Magnesium turnings and chips are produced by milling commercial and high-purity magnesium, keeping size under control to obtain the desired specific surface and reactivity. They are silver-white. initially, but can turn to a dark gray if stored improperly.

Standard purity (99.8% Mg)
Ultra-high purity (99.98% Mg)

Typical Applications

Magnesium is used in products that benefit from being lightweight, such as car seats, luggage, laptops, cameras, and power tools. Its alloys have a variety of uses, including airplane and missile construction. It is used in the electronics industry to manufacture mobile phones, laptop and tablet computers, cameras, and other components. Magnesium is used in pyrotechnics, firework sparklers, flares, and flash photography. It is also used as a desulfurizer in the iron and steel industry.

Packaging Options

Mylar-aluminum bags, pails, fiber & steel drums, and bulk bins.
