Milled plate Milled Alcast EN AW 7021

Milled Alcast is a cast and subsequently milled alloy 7021 T6 with a controlled 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 and highly appreciated for the production of precision mechanical components that require considerable mechanical properties, as well as a high degree of formal stability.

The main characteristic that distinguishes this alloy from rolled products is its high degree of dimensional stability.

TECHNICAL CHARACTERISTICS

Weldability:

TIG/DC: good for repairs
Wire: AA 5183

Surface treatments

Hard anodisation: good
Suitability for polishing: optimal

Workability
Milled Alcast is easy to work and allows for high-speed processing thanks to its exceptional formal stability, the absence of any undesired crystalline structures, and its fine and compact microstructure.

Resistance to corrosion

Normal atmospheres: good
