C14500 los yog tellurium tooj liab muaj cov khoom zoo sib xws rau cov tooj liab tsis muaj hlau, tab sis nrog ntau dua machinability. Los ntawm kev ntxiv tellurium rau tooj liab alloy, qhov kev ua tau zoo ntawm C14500 tau raug txhim kho zoo. Tellurium tooj liab tseem paub txog nws cov hluav taws xob hluav taws xob siab.

Cov khoom siv hluav taws xob ntawm tooj liab C145 ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv lub zog siab xws li cov khoom siv tsheb lossis cov fasteners. Nws muaj lub zog tensile zoo heev (550-650 MPa) thiab lub zog tawm los (200-300 MPa). Nws elongation yog nyob ntawm 10-20%. Cov khoom no kuj muaj qhov zoo ductility, uas ua rau nws yooj yim rau kev tsim cov duab thaum machining lossis vuam.
Tsis tas li ntawd, nws cov machinability ua rau nws muaj txiaj ntsig zoo hauv kev tsim cov duab zoo nkauj lossis cov qauv tsim uas xav tau rau qhov nyuaj xws li lub zog lossis cov kabmob. Thaum kawg, nws cov weldability tso cai rau qhov yooj yim koom ua ke ntawm ntau qhov chaw rau hauv ib qho cohesive piece yam tsis tau poob ib qho kev ncaj ncees thaum lub sij hawm.
Raws li tau hais dhau los, Copper C145 muaj qhov zoo tshaj plaws corrosion kuj ua rau nws zoo tagnrho rau siv hauv marine thiab kev lag luam daim ntawv thov uas raug rau hnyav ib puag ncig tej yam kev mob. Nws tseem tuaj yeem siv rau hauv cov khoom siv hluav taws xob vim nws cov ntsiab lus tsis tshua muaj leej faj, uas ua kom cov hluav taws xob tsawg tsawg thaum ua cov khoom siv tam sim no.
Copper C145 muaj cov cua kub zoo ua rau nws tsim nyog siv rau hauv qhov chaw kub kub uas kub tshaj 650 degree (1200 degree F). Lub alloy tuaj yeem khaws nws cov duab ntawm qhov kub thiab txias yam tsis muaj deforming lossis ua nkig zoo li qee cov hlau yuav nyob rau ntawm qhov kub siab dua.
Nyob ntawm cov ntawv thov, cov khoom siv no tuaj yeem kho nrog ntau yam kev kho cua sov los txhim kho nws lub zog thiab hardness ntxiv.
Nyob rau hauv cov nqe lus ntawm machining muaj peev xwm, cov ntaub ntawv no tau yooj yim txiav siv txheem txiav cov cuab yeej xws li xyaum thiab saws; Txawm li cas los xij, lawv xav tau kev saib xyuas ntxiv vim lawv nyiam ua haujlwm hnyav thaum lub sijhawm tsim cov txheej txheem, ua rau cov cuab yeej hnav ntau dua lub sijhawm yog tias tsis saib xyuas zoo txaus thaum lub sijhawm tsim khoom.
Raws li kev vuam mus, cov hlau no yooj yim yooj yim los koom ua ke siv MIG lossis TIG vuam cov txheej txheem; Txawm li cas los xij, cov flux yuav tsum tau siv tas li thaum ua tau, vim qhov no yuav ua kom muaj kev sib koom ua ke ntawm ob daim hlau yam tsis muaj kev cuam tshuam kev ncaj ncees thaum lub sijhawm ua haujlwm nws tus kheej.
