7020 SAWED CAST ALLOY

7020 Sawed Cast Alloy

Aluminum alloy 7000 with a high percentage of zinc (5,00-6,00) and magnesium (0,7-1,2). The plates are obtained by belt sawing huge blocks of cast alloy.
It has good mechanics characteristics and can be easily wrought by means of machine tools. The shape stability is good as well.

Applications:
Peculiar constructions where both good shape stability and mechanical characteristics are required, like transport elements, tooling, injection molds and plastic molding.
