This is usually found in really cheap products and looks and sounds metallic (rings a bit when dropped) , but I’m not sure if it is one.

The pictured cross section shows the greyish metal (the gold is just paint).

The cross section feels coarse and has tiny glittering specks. It also looks a bit porous (tiny air bubbles seem to be present in this alloy)

It’s also pretty weak - a pencil like object made from this stuff can easily be snapped in two with your bare hands.

Thanks!
