Milled plate
Precisal Cast 50
EN AW 5083

Precisal Cast 50 is a cast and subsequently milled product with a minimal planarity tolerance and a thickness tolerance with a resolution of a tenth of a degree.

In order to ensure maximum protection, both faces are protected with 2-sided 100 micron laser PVC film. Used for the production of precision mechanical components that require high-formal stability.

The main characteristic that distinguishes this alloy from rolled products is its high degree of dimensional stability both during and after processing.
