Isampula 375 zegolide

Gold sisinyithi kuphela ehlabathini, ukuba zintle eqaqambileyo emthubi ecocekileyo ngaphandle kudla. zegolide zemvelo ukukhazimla elungileyo, nto leyo ngcono kakhulu ipolishi. Ngokuqhelekileyo, igolide afunyenwe zingaxhatshazwa iidipozithi zendalo, okanye bapase nezokukhupha ezinye iintsimbi ezivela ores. igolide Native yendalo ngokufanayo nyulu, kuba iqulathe njengoko ubumdaka eziphambili ubhedu, isiliva, kwakunye eyongezelelweyo udibana nezinye izinto ezininzi. Ngoko ke, ngenjongo zokwenza nyulu ngegolide layo phantsi unyango ezizodwa (yokucokisa) kwimigodi yegolide.

igolide esulungekisiweyo sele udibanise 99,99% ngohlobo bars, ucingo, ngefoyile, strip kunye nezinye ukutya lula. Kule fomu ngayo ithambe kakhulu kwaye ductile otyhidiweyo, umzekelo ukusuka yegram enye kwicingo metal ibe elingatsalanga isiqingatha ubude neekhilomitha ezintathu. Ishishini jewelry ekuveliseni yomhombiso yegolide sele asetyenziswe aluminium ezahlukeneyo. Zonke ezi aluminiyamu kuba umxholo othile zegolide, yaye ngako oko abelwe lesampula. Umxholo lisezantsi metal kuwe 375 isampuli yegolide.

Aluminiyamu yale isampuli iqanjwa% 37,5 kuphela ngegolide ecocekileyo, ezinye macandelo yobhedu nezesilivere. maxa wambi imboni Iingcali izacholo bayibiza igolide-yobhedu nesilivere ingxubevange. Ngokutsho kwimilinganiselo Russian 5 iintlobo aluminium ukuba uyasetyenziswa apho 375 sample igolide. Zonke ezi aluminiyamu yaphela apha emoyeni okukufutshane, ngoko olu phawu umda kakhulu isicelo sabo. Lonke uluhlu imibala ezi aluminiyamu isusela ukusuka mthubi ukuya obomvu, kodwa amaninzi ngexesha elinye becala ingxubevange 585 ekuthiwa-"samovar" ngegolide ebomvu. Aluminiyamu ukuba umbala epinki, zezona ixesha elide kakhulu yaye nzima, abasabela kakuhle ukuba yokudla.

Nangona oku iisampulu igolide ephantsi, lisetyenziswa kwishishini jewelry. Ngokuqhelekileyo, ezi aluminium zisetyenziswa ekwenziweni amakhonkco yomtshato. Kwi-Russian Federation kukho isampuli akukho aluminium ezikumgangatho ophantsi, kodwa kumazwe aseYurophu kusetyenziswa iisampuli zegolide 333, nto leyo nayo kusetyenziswa ukwenza izacholo, nezidanga. aluminiyamu Gold ezaqanjwa ezahlukeneyo ezisetyenziswa kushishino jewelry, njengoko xa kongezwa imibala eyahlukileyo kuyenzeka ukufumana aluminium ezahlukeneyo inkosi: ebomvu, ezipinki, eluhlaza okanye kumhlophe, kwakunye noluhlu elikhulu imibala ephakathi.

Amaxesha amaninzi ekuveliseni izacholo kusetyenziswa aluminiyamu, ebandakanya amacandelo amaninzi. Ukuba isampuli igolide 375 ifunyenwe ikakhulu ngenxa ukongeza sobhedu nesilivere ingxubevange, zesampulu ezishiyekileyo njengoko ezihlangene nazo zisetyenziswa palladium, platinum, izinc, isiqalelo esithambileyo esimhlophe ne-nickel. Icandelo ngalinye ingxubevange uyakwazi ukulobola iipropati ezahlukeneyo. Silver yenza ductile ingxubevange yegolide ngakumbi oluthambileyo ngokukhanya. Ukongeza sobhedu kwandisa yobulukhuni ingxubevange, kodwa ukuxhathisa yayo umhlwa xa isihla ngokuhla. Kwakhona, i intsila onjalo ufumana nombala obomvu oqaqambileyo.

Ukudibanisa isiqalelo esithambileyo esimhlophe, yenza ingxubevange fusible kwaye isoloko isetyenziswa igolide-solder. Inika iimpawu ezifanayo, nezinki, ukongeza, yena lula ingxubevange, nto leyo eyenza kube lula ukuyisebenzisa kuyo ekwenziweni ngegolide emhlophe. Ezi izinyithi eninzi ezifana platinum kunye palladium-igolide aluminium ukunikeza plasticity, luthambe kwaye yenze lula kakhulu kubo. Ukongeza, ukuba babanike ukuxhathisa eliphezulu umhlwa. Noko ke, igolide 375 nesampula lukhutshwe ngokongeza lwezi methali. Iinkalo eziphambili zezi igolide, nesilivere nobhedu ngenxa yakhe.
