Aerospace Aluminium Sheet

L16 Aerospace Aluminium Sheet

Aerospace aluminium sheet grade L16/L17 has high corrosion resistance with slightly higher strength than 1050A.

High Thermal Conductivity

The alloy also boasts high thermal conductivity and reflectivity although this is not relatively as high as 1050. The alloy has a 99% minimum requirement for aluminium content and yet is still classed as a non-heat-treatable commercially pure aluminium. Alloy L16 is temper designation H14 or H24; Alloy L17 is 'O' temper.


L16 / L17 aluminium sheet has high thermal conductivity and very good weldability. The alloy is easily joined and has high anodising capability. The material offers very good resistance to atmospheric corrosion.

Typical Applications

Commercial applications for this engineering material include:

  • General fabrication
  • Aerospace components
  • Processing equipment (chemical, pharmaceutical)
  • Sheet metal work
  • Boiler fabrication
  • Industrial pressure vessels (food sector)
  • Kitchenware

We stock L16 / L17 in sheet and strip.
