Aluminum 2018
Aluminum 2018 is a high-strength, heat-treatable aluminum alloy primarily alloyed with copper and magnesium. It is designed for applications requiring superior mechanical strength, good fatigue resistance, and reliable performance under load.
This alloy is most commonly used in aerospace and structural applications where strength is critical. While Aluminum 2018 offers excellent mechanical properties, it has lower corrosion resistance compared to some general-purpose aluminum alloys and is typically used in controlled environments or with protective finishes.
Aluminum 2018 is commonly supplied in bar, rod, plate, and sheet forms and can be provided to meet applicable aerospace and industry specifications.
Aluminum 2018 FAQ
What is Aluminum 2018 used for?
