Introduction
Aluminium / aluminum 7000 series is considered as the highest strength series of aluminum alloys developed primarily for aircraft applications. It is vital to the aerospace industry because of its corrosion-resisting qualities, comparative ease of fabrication, and high strength/weight ratio. Zinc is the primary alloy of this series.
Aluminium / aluminum 7004 alloy is a wrought alloy. The following datasheet will provide more details about aluminium / aluminum 7004 alloy.
