Copper alloys are used in jewllery.
- brazing metal for zirconium and zirconium alloys- copper alloys for welding electrodes- element in neutron sources- reflector in nuclear reactors- windows of X-ray tubes
the green patina of copper is desirable

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
The use of beryllium, is used as missiles, and rockets. Windows for X-ray tubes, brazing material for zirconium alloys, beryllium bronzes, beryllium alloys for welding, nuclear applications as reflector, beryllium-copper alloys for Transformers, Ra-Be source of neutrons, alloys for aviation industry, alloys for missiles, alloy for watches components, etc. Beryllium oxide: electric insulator but thermal conductor, ceramics for high temperatures, nuclear applications as neutrons reflector, etc.
Copper (as a metal or alloys) is safe.
