Copper grades are divided into six families: coppers, dilute copper alloys, brasses, bronzes, copper-nickel alloys, and nickel-silver alloys. The grade depends on the composition.

the copper is oxidizing
Pure copper is actually quite useful for certain purposes, such as wiring, but alloys such as brass and bronze are stronger than copper.

i don't think they had the technology available to create alloys during the copper age

Copper (as a metal or alloys) is safe.
Iridium can form alloys with copper.
