A Guide to 5251 CNC Machined Parts: Properties, Applications and Design Considerations

What is 5251?Aluminium Machined Enclosure Lid

Aluminium 5251 is a medium strength magnesium manganese alloy best known for its good ductility and formability.

It has high corrosion resistance, and as a result is commonly used in marine environments.

5251 is traditionally recognised as a general sheet metal working grade. It is not heat treatable to higher strength.

Main Attributes of 5251:

  • Good surface finish & aesthetic properties
  • High corrosion resistance
  • Very good weldability
  • Good anodising properties
  • Good mechanical properties
  • Medium strength
  • High fatigue strength
  • Low density
