Properties of Magnesium Alloy

Mechanical properties of magnesium alloys including AZ31B sheet and plate and ZK60A wrought magnesium

Where is Magnesium used?

  • Aerospace, defense and satellite applications where weight reduction is critical
  • Electronic components where shock absorbing qualities are crucial
  • Automotive/Motor sports applications where weight reduction and strength are required
  • Mechanical vibration shakers for test fixtures

Why Magnesium?

  • Magnesium is the lightest industrial metal in the world
  • One third lighter than aluminum
  • Magnesium is as strong as aluminum
  • Magnesium is shock absorbing and dampens vibrations
  • Magnesium is very machinable
  • We supply AZ31, AZ61, AZ80, and ZK60 alloys in a range of tempers and product forms to meet ASTM B107 and AMS specifications.
