What would be the hardest element except for carbon(diamonds)? i am suggesting titanium, tungsten carbide, forged steel or 7075 aluminium or any other variety of a element or alloy. also what would be the lightest metal(titanium?)? Please share what you know.

It's not an element, but the hardest plastic is UHMW-PE (ultra-high-molecular-weight poly-etheylyine or something like that...) and it's used in aggressive inline skating parts because it's durable and slides really fast...

not like that's what you were wanting to know though...

first off.. diamonds are minerals.

so if we are talking minerals, second to diamonds corundum (aluminum oxide) would be about the second harders (a 9 on Moh's scale of hardness, whereas diamonds are 10).

elements are a completely different story, but it seems as though you aren't talking strictly elements.

as far as lightest metal (element-wise, and also the lightest solid), Lithium wins.
