Magnesium Die Casting

About Magnesium Die Casting

Magnesium alloys die casting is a quite popular metal die casting manufacturing process in the manufacturing industry. Even though magnesium die casting is done in different methods, but its goal is to produce high strengths and light weight casting parts. Normally magnesium alloy combines with other metals  like aluminum, zinc , copper, etc. It’s widely used in automotive, lighting, home appliances, and other consumer products.

  • The best strength and stiffness of any commonly used structural metal.
  • The lightest of all structural metals
  • Excellent dimensional stability as well as high impact and dent resistance.
  • God conductivity, electrical, and thermal property
  • Cost-effective compared with many engineering materials
  • Good environmental corrosion resistance
  • Consistent and predictable shrink rates mean minimal distortion or casting stress
  • Good finishing characteristics

Magnesium Die Casting  VS. Plastic Injection Molding

  • Much stronger and greater wear resistance than plastic parts.
  • Superior stiffness as plastic often requires significant reinforcing.
  • Greater impact resistance and energy absorbing capacity.
  • Superior thin-walled near net shape casting of larger parts.
  • Higher temperature applications than plastic parts.
  • More stable in dimensional control.

Magnesium Die Casting  VS. Steel

  • 70% lighter than steel.
  • Complicated thin-walled near net shape casting that would be impossible to achieve using steel.
  • Consolidation of individual components into a single die cast magnesium part, which improves rigidity while reducing welding costs and assembly time associated with steel.
  • Tooling costs are significantly reduced due to consolidation of multiple parts into a single part.
  • More stable in dimensional control.

Magnesium Die Casting  VS. Aluminum Die Casting

  • 30% lighter than aluminum.
  • Similar or greater mechanical properties.
  • Lower working temperatures extend die life and reduce energy consumption during production.
  • Machining is faster and easier and machining tools last significantly longer.
  • Superior thin-walled near net shape casting of larger, more complex parts so there are fewer components and less assembly required.
  • Better surface appearance than aluminum die casting parts.
