Mg – Magnesium is strong, rigid, fully recyclable, lighter than many types of plastics and has excellent shielding properties, making it an ideal alloy to save weight without sacrificing durability and safety.

Properties of the magnesium alloy:
  • The lightest of all structural metals
  • Excellent rigidity and excellent strength-to-weight ratio
  • Excellent EMI & RFI shielding properties
  • High conductivity, both electrically and thermally
  • Can withstand high operating temperatures
  • Inexpensive compared to many technical thermoplastics materials
  • High dimensional accuracy and stability
  • Exceptional opportunities for thinner wall thickness
  • Good surrounding corrosion resistance
  • Good finishing properties
  • Full recyclability

Magnesium is the ideal material when trying to save on weight because it has the lowest density of all structural metals. Lighter than even some types of plastics, magnesium has the advantage of greater strength and flexural rigidity along with inherent EMI/RFI shielding, high durability, thermal conductivity and full recyclability.

Injection Molding is a casting method where magnesium is simultaneously sheared and heated until it becomes dough-like in consistency, and then injected into a mold, creating a laminar flow front similar to that of plastic injection molding. The doughy consistency is created in a magnesium injection molding machine under a protective gas. The magnesium is heated to 560° to 600° C via a feed screw and external heating, and then pressed into the die. The duration of the injection process including dwell-pressure is about 0.03 seconds; the cycle time, depending on component size, is about 20 to 45 seconds. The laminar flow front created during the Injection Molding process ensures the production of components with more uniform material structure and lower porosity and/or cavity-free compared to die casting.

Magnesium is an important production material for components thanks to its low density, sufficient strength, available economic production, high recycling potential and high availability. It is currently used almost exclusively in the field of automotive technology, though on a comparatively small scale. Magnesium materials are essential in innovative vehicle concepts especially when it comes to lightweight construction.
Pioneering research and development work in recent years has heightened interest in this material group, leading to new ideas and impulses. Areas such as traffic engineering and general engineering, for example, could benefit greatly from magnesium’s potential.
