A380 Aluminium Alloys: Properties, Applications and Advantages

A380 aluminum alloy

Aluminum alloy type A380 is the most common specialized aluminum alloy because it combines the characteristics of easy casting, easy machining, and good heat transfer. It is highly resistant to shifting, pressure, and high-temperature splitting. It is used in various products, including motor equipment chassis, engine mounts, gearboxes, furniture, generators, and hand tools, and can be used in almost any industry.

A380 Aluminum Alloy Advantages

Lightweight: Aluminum enables lighter parts to be produced, making it suitable for lighter components with good strength.

Good machinability: A380 alloy has excellent machinability and is, therefore, suitable for different surface finishing types. For example, anodizing, shot peening, powder coating, etc.

Excellent resistance to thermal cracking: Aluminum A380 has excellent resistance to thermal cracking and can be heat treated.

High corrosion resistance: A380 alloy parts have excellent corrosion resistance. Components are less likely to be damaged by corrosion, so the service life is extended.

Good dimensional accuracy and dimensional stability: Aluminum A380 alloy has excellent dimensional stability, does not deform and has very good pressure sealing.
