① Ngokwefomu elikhona ngokwemvelo

Ithusi lemvelo;

I-Copper oxide;

I-Copper sulfide.

② Ngokwenqubo yokukhiqiza

I-Copper concentrate - i-ore enokuqukethwe kwethusi okuphezulu okukhethiwe ngaphambi kokuncibilika.

I-copper engahluziwe --- umkhiqizo we-copper concentrate ngemva kokwelashwa, enethusi elingu-95-98%.

Ithusi elihlanzekile - ithusi eliqukethe ngaphezu kwama-99% ngemuva kokucwenga umlilo noma i-electrolysis.I-99-99.9% yethusi ehlanzekile ingatholakala ngokuncibilikisa umlilo futhi ingatholakala nge-electrolysis.

③ Ngokusho kokwakheka kwe-alloy main

Ithusi -- ingxubevange ye-zinc yethusi

Ithusi - i-copper tin alloy, njll. (ngaphandle kwe-nickel ye-zinc, ama-alloys anezinye izakhi abizwa ngokuthi i-bronze)

Ingxubevange ye-nickel yethusi yethusi yethusi

④Ngokwefomu lomkhiqizo:

Ipayipi lethusi, induku yethusi, ucingo lwethusi, ipuleti lethusi, umugqa wethusi, umugqa wethusi, ucwecwe lwethusi, njll.
