Which symbol represents the element Copper?

Explanation:
Copper’s symbol is Cu, drawn from its Latin name cuprum. The capitalization matters: a capital C followed by a lowercase u. The other symbols come from different elements—Fe is iron, Mn is manganese, and Ni is nickel—so Cu is the one that correctly represents copper. This symbol usage helps you quickly identify base metals and filler materials in welding applications and ensures you’re aligning with the right material properties.
