If I remember right the lifting eye was cad although mine is all worn off with my polishing. The alt brackets are aluminum I think, upper is welded with no trace of rust, the bottom was worn oval were the bolt goes through so I had a steel bush pressed in. The bracket seemed light and soft and lack of surface rust made me think aluminum/aluminum alloy.
