Description

DIN 3.4384, derived from Aluminum 7075, provides excellent toughness for a broad variety of applications. This alloy offers several metalworking options that include machining, forming, and heat treating. For machining, DIN 3.4384 functions best in the annealed condition and should be used with oil-based lubricants. It is also most easily formed in the annealed condition, as its hardened state results in spring-back. This alloy is typically available in flat rolled products, and it is widely used for applications that require high strength, including planes and other aerospace assemblies.
