Umcu wobhedu
Intshayelelo yeMveliso
Iphepha leBrass elisekwe kwi-electrolytic copper, zinc kunye nezinto ezilandelelanayo njengezinto zalo eziluhlaza, ngokusebenzisa i-ingot, i-hot rolling, i-cold rolling, unyango lobushushu, ukucoca umphezulu, ukusika, ukugqiba, kunye nokupakisha. Izinto zisebenza ngendlela yokusebenza, i-plasticity, iipropati zoomatshini, ukumelana nokugqwala, ukusebenza kunye ne-tin elungileyo. Isetyenziswe kakhulu kumashishini ombane, eemoto, onxibelelwano, kwi-hardware, ekuhombiseni nakwamanye amashishini.
