Sharaxaada Alaabta
Xadhkaha iska caabbinta ee la dahaadhay ayaa si balaadhan loogu isticmaalay iska caabiyeyaasha caadiga ah, baabuurta
Qaybaha, iska caabiyeyaasha dabaysha, iwm. iyadoo la adeegsanayo habka dahaarka ee ugu habboon codsiyadan, iyadoo si buuxda looga faa'iidaysanayo sifooyinka gaarka ah ee dahaadhka dhaldhalaalka.
Intaa waxa dheer, waxaanu samayn doonaa dahaarka dhaldhalaalka ee siligga birta ah ee qaaliga ah sida qalinka iyo siliga platinum marka la dalbado. Fadlan ka faa'iidayso wax-soo-saarkan-dalbashada.
Nooca Silig Aloy Bare
Daawaha aan samayn karno ee la dahaadhay waa Copper-nickel alloy silig, silig Constantan, silig Manganin. Kama Wire, NiCr Alloy silig, FeCrAl Alloy silig iwm silig daawaha

Sharaxaada naxaasta:
Copperwaa curiye kiimiko ah oo sumad lehCu(laga soo bilaabo Laatiinka:koobabka) iyo lambarka atomikada 29. Waa bir jilicsan, la boodboodi karo, iyo ductile leh kulayl iyo koronto aad u sarreeya. Oogada cusub ee naxaasta saafiga ah ee dusha sare ah ayaa leh midab casaan-orange ah. Copper waxaa loo isticmaalaa sida kirishbooyada kulaylka iyo korontada, sida qalab dhismo, iyo sida qayb ka mid ah Alloys biraha kala duwan, sida lacag isteerin ah oo loo isticmaalo dahabka, cupronickel loo isticmaalo samaynta qalabka badda iyo qadaadiic ah, iyo joogto ah loo isticmaalo in lagu miisaameeyo iyo thermocouples. cabbirka heerkulka.
Copper waa mid ka mid ah biraha yar ee ku dhici kara dabeecadda qaab macdan ah oo toos ah oo la isticmaali karo ( biraha asalka ah). Tani waxay keentay isticmaalka bini'aadamka oo aad u horeyay dhowr gobol, laga bilaabo c. 8000 BC. Kumanaan sano ka dib, waxay ahayd birihii ugu horreeyay ee laga dhalaaliyo macdanta sulfide, c. 5000 BC, birta ugu horeysay ee lagu tuuro qaab caaryar ah, c. 4000 BC iyo birta ugu horeysay ee si ula kac ah loogu dahaadhay bir kale, tiin, si loo abuuro naxaas, . 3500 BC.
Iskudhisyada sida caadiga ah loola kulmo waa cusbada naxaasta (II), kuwaas oo inta badan siiya midabyo buluug ama cagaar ah macdanta sida azurite, malachite, iyo turquoise, waxaana si ballaaran iyo taariikh ahaan loo isticmaali jiray midab ahaan.
Copper loo isticmaalo dhismayaasha, sida caadiga ah saqafka, oxidizes si ay u sameeyaan verdigris cagaaran (ama patina). Copper waxaa mararka qaarkood loo isticmaalaa farshaxanka qurxinta, labadaba qaabka birta aasaasiga ah iyo isku dhafka sida midabada. Iskudhisyada Copper waxaa loo isticmaalaa sida wakiilada bakteeriyada, fungicides, iyo ilaalinta alwaaxyada.
Copper waxay lama huraan u tahay dhammaan noolaha noolaha sida raadraaca macdanta cuntada sababtoo ah waa qayb muhiim ah oo ka mid ah ensaymes neefsiga kakan ee cytochrome c oxidase. Molluscs iyo crustaceans, naxaasku waa qayb ka mid ah midabka dhiigga ee hemocyanin, oo lagu beddelo haemoglobin-ka-kashan ee birta ee kalluunka iyo laf dhabarta kale. Bini'aadamka, naxaasta ayaa inta badan laga helaa beerka, muruqa, iyo lafaha. Jirka qaangaarka ah wuxuu ka kooban yahay inta u dhaxaysa 1.4 iyo 2.1 mg oo naxaas ah kiilooga miisaanka jidhka.
