metals have a hardness waffle. It depends on what materials are inside to a metal compound. I use aluminium 7075 that has the biggest hardness of all aluminium alloys. When I say middle steel I mean that steel is a very hard metal but people want to make even harder metals for other use, so they make steel alloys or they "paint" the steel to make it very hard or they put inside carbon and other materials.
Hardness is meassured in brinel (if I remember well) that is a scale of hardness. I dont know the hardness of the steel that has low carbon in it but this aluminium alloy is harder than than some kind of steel-carbon alloys
I also cant give you an everyday example because I dont know from witch kind of steel some things are made. But if an aluminium alloy can be harder than any kind of steel then this is a very big fact!
I searched a lot to find what I want for GG, I want to have always the best as you know
