Aluminium Alloy A380

Aluminium Die Casting Alloy

A380 is one of the most commonly specified Aluminium alloys with a number of significant benefits:

  • It offers the best combination of casting, mechanical, and thermal properties
  • It exhibits excellent fluidity, pressure tightness, and resistance to hot cracking
  • It is used for a wide variety of products including chassis for electronic equipment, engine brackets, gearbox cases, household furniture, power, and hand tools

Advantages of Aluminium Die Casting

Aluminium has the ability to create lighter parts with more surface finishing options than other die cast alloys. Aluminium can also withstand the highest operating temperatures of all the die cast alloys. Moreover, cast Aluminium is versatile, corrosion resistant; it retains high dimensional stability with thin walls, and can be used in almost any industry.
