Magnesium Metals & Alloys

Magnesium is a chemical element with symbol Mg and atomic number 12

It is the 8th most abundant element found in the crust of Earth

Magnesium is the LIGHTEST STRUCTURAL METAL. To makeup for the added weight and volumes, many manufacturers are turning towards light commercial alloys of Magnesium.

Magnesium metals and alloys are going to be the game changers in the Aerospace Industry, Defence Industries, Manufacturing of Drones, Robotics, Light Metal Parts

Magnesium Metals Alloys: are made with Aluminium from 3 to 13%, Manganese 0.1 to 0.4%, Zinc 0.5 to 3%. These alloys are used for Cast & Forged components

  • AZ63 & AZ92 are used for Sand Casting
  • AZ91 is used in Die Casting
  • AZ92 for Mold Casting
  • AZ61 & AZ80 is used for Forging
  • AZ31, AZ61, AZ91, AZ80 are used for making finish products
