C12200 Copper Chemical Properties
Qhov sib ntxiv ntawm cobalt rau cov tooj liab ntshiab tsim ib qho alloy uas muaj qib siab hnav tsis kam tshaj cov tooj liab ntshiab. Tsis tas li ntawd, nws nta superior kub-shortness thiab siab hardness ntawm siab kub thaum piv rau lwm yam tooj liab alloys. Copper C122 yog ib qho ruaj khov thiab corrosion-resistant alloy uas nta nws qhov sib xyaw ua ke ntawm cov khoom siv kho tshuab, hnav tsis kam, thiab qis coefficient ntawm kev sib txhuam. Nws yog cov hlau uas muaj tooj liab, npib tsib xee, chromium, thiab molybdenum, uas muab nws lub zog tensile zoo dua thaum piv rau lwm cov hlau alloys. Tsis tas li ntawd, nws cov khoom siv tau zoo heev nyob rau hauv ob qho tib si acidic thiab alkaline ib puag ncig, ua rau nws qhov kev xaiv zoo tshaj plaws rau ntau daim ntawv thov. Copper C122 muab qhov tshwj xeeb rov ua dua thiab raug nyob rau hauv machining thaum tseem muaj kev cuam tshuam toughness vim nws muaj peev xwm ua hauj lwm nyuaj yam tsis poob. Cov khoom no ua rau nws nyiam alloy rau ntau qhov kev lag luam uas muaj txiaj ntsig zoo rau kev ua haujlwm thiab kev ntseeg siab.
C12200 Copper Mechanical Properties
Copper C122 yog cov khoom siv ntau yam uas nthuav tawm cov khoom siv zoo heev uas ua rau nws zoo tagnrho rau ntau daim ntawv thov kev lag luam. Nws thermal expansion coefficient zoo sib npaug, thiab nws lub zog-rau-qhov hnyav piv yog siab txaus kom nws ruaj khov heev txawm tias huab cua txias. Nws tsis tshua muaj coefficient ntawm kev sib txhuam ua rau tooj liab C122 yog ib qho khoom siv zoo rau tribological Cheebtsam, xws li bearings, bushings thiab gears. Tsis tas li ntawd, tooj liab C122 muaj cov yam ntxwv zoo heev ua tsaug rau nws lub peev xwm ua haujlwm hnyav, ua kom nws zoo rau kev siv hauv cov tshuab ua kom tsis zoo. Tsis tas li ntawd, tooj liab C122 boasts superior corrosion kuj thiab zoo heev hluav taws xob conductivity, ua rau nws tsim nyog rau lub sij hawm uas yuav tsum tau ib tug sib npaug ntawm ob qho tib si hluav taws xob kev twb kev txuas thiab mechanical kev ua tau zoo. Copper C122 tiag tiag nyob rau hauv nws lub koob npe nrov raws li cov khoom siv tseem ceeb.
C12200 Copper Physical Properties
Copper C122 yog cov hlau uas muaj cov yam ntxwv zoo weldability. Nws muaj qhov sib txawv ntawm qhov sib txawv ntawm 1730-1790 degree F (945-980 degree ). Nws lub zog tensile ranges ntawm 60-90 ksi (414-621 MPa) nyob ntawm cov txheej txheem kho cua sov siv thaum tsim khoom.
C12200 siv tooj liab
Nws feem ntau siv rau cov khoom siv hauv aerospace engineering daim ntawv thov nrog rau kev tsim khoom siv kho mob.
Corrosion Resistance
Vim nws qhov zoo tshaj plaws corrosion kuj zoo, Copper C122 feem ntau yog siv rau hauv cov ntawv thov uas raug rau cov tshuaj hnyav los yog qhov chaw corrosive.
Cov txheej txheem kho cua sov
Kev kho cua sov feem ntau siv rau cov hlau no yog annealing thiab tshuaj kho / nag lossis daus hardening (ST / PH). Annealing muaj cua sov cov hlau saum toj no nws cov recrystallization kub ua ntej maj mam txias nws nyob rau hauv thiaj li yuav nce nws ductility thiab formability yam ntxwv. Kev kho / nag lossis daus hardening nce cov khoom hardness los ntawm kev tsim precipitates nyob rau hauv cov hlau uas ntxiv dag zog rau nws tiv thaiv hnav los yog tsim kua muag thaum lub sij hawm.
Tshuab dhos
Vim nws cov thermal conductivity siab (400 W / mK), machining nrog tooj liab C122 tuaj yeem nyuaj vim yog cov cuab yeej siv ceev nrooj los ntawm kev kub ntxhov ntau dhau thaum ua haujlwm txiav.
Vuam
Thaum welding cov khoom no, nws yuav tsum tau preheated ua ntej welding thiaj li yuav tiv thaiv tau tawg thaum lub sij hawm txias vim ceev thermal expansion sib txawv ntawm lub hauv paus ntaub ntawv thiab muab tub lim hlau siv thaum lub sij hawm vuam ua hauj lwm.
