L80 / L81 Aluminium SheetL80 / L81

Aluminium Sheet

Alloy L80/L81 is an aluminium sheet product which is recognised as a general sheet metal work grade.

The material offers high marine corrosion resistance with good weldability and very good cold formability. The alloy is also known for rapid work hardening so care needs to be taken in the forming process. L80/L81 is used in the manufacture of aircraft parts and structural marine applications among many others.

Key Features:

L80 / L81 aluminium sheet offers good ductility and formability and is readily weldable. With high resistance to marine corrosion and very good anodising properties, this aesthetically pleasing medium strength alloy benefits from rapid work hardening.
