Aluminum Alloy, Die Castings 8.5Si - 3.5Cu (A390.0-F0 (See AS 1990) As Cast
This specification covers an aluminum alloy in the form of die castings. These castings have been used typically for components of intricate shape, but not having thin sections, but usage is not limited to such applications. This alloy has good casting characteristics by cold-chamber die casting and fair resistance to corrosion.
