Material-Cast Aluminum Alloy-A380

A380 is one of the most commonly specified aluminum 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
Aluminum has the ability to create lighter parts with more surface finishing options than other die cast alloys. Aluminum can also withstand the highest operating temperatures of all the die cast alloys. Moreover, cast aluminum is versatile, corrosion resistant; it retains high dimensional stability with thin walls, and can be used in almost any industry.




Comparison of Casting Processes

Casting Process Advantages Limitations
