Need Help Identifying Items Found Near Sebastian Florida

[GG84]

These items were found mid beach in dense black sand following the winter storm that produced strong southern waves. Between Sebastian and Vero Beach Florida. Need help identifying. Thanks.

To me, and I'm no expert, the finds look like melted aluminum and possibly other metals. Possibly from beach campfires and or burning boats.

I understand that some precious metal dealers have a device called an XRF that can analyze metals. Looking at your pics with scales their weight rules out lighter metals IMO.
