piav qhia luv luv
Ntshiab tooj liab yog purplish liab, yog li nws kuj hu ua liab tooj liab. Nws muaj qhov zoo tshaj plaws thermal conductivity thiab conductivity. Nws conductivity yog thib ob tsuas yog nyiaj, thiab nws nyob qib thib ob rau hlau. Tooj liab muaj cov tshuaj zoo heev ruaj khov thiab corrosion kuj, thiab yog cov khoom siv hluav taws xob zoo heev.
kev faib tawm
Copper alloys dav siv hauv kev lag luam xws li tooj dag, tooj liab thiab dawb tooj liab.
Cov alloy ntawm Cu thiab Zn yog hu ua tooj dag, uas Cu nyiaj rau 60 feem pua ~ 90 feem pua thiab Zn suav rau 40 feem pua ~ 10 feem pua. Nws muaj cov thermal conductivity zoo thiab corrosion kuj thiab tuaj yeem siv los ua cov khoom siv ntau yam. Lwm qhov piv txwv yog ntxiv ib qho me me ntawm Sn rau hauv tooj dag, uas yog hu ua naval tooj dag thiab muaj peev xwm tiv taus dej hiav txwv. Ib qho me me ntawm Pb nrog cov nyhuv lubricating yog ntxiv rau hauv tooj dag, uas tuaj yeem siv los ua cov khoom siv zawv zawg.
Bronze yog cov khoom siv hlau uas muaj keeb kwm ntev tshaj plaws ntawm tib neeg siv. Nws yog Cu, Sn alloy. Qhov sib ntxiv ntawm tin pom tseeb txhim kho lub zog ntawm tooj liab, txhim kho nws cov yas, thiab txhim kho nws cov corrosion kuj. Yog li ntawd, tin bronze feem ntau yog siv los tsim cov khoom hnav-resistant thiab corrosion resistant accessories xws li iav. Sn yog kim dua, thiab cov khoom siv tooj liab tau txais los ntawm kev hloov Sn nrog Al, Si thiab Mn. Qhov corrosion kuj ntawm aluminium bronze yog zoo dua li ntawm tin bronze. Beryllium bronze yog tooj liab alloy nrog lub zog siab tshaj plaws. Nws yog nonmagnetic thiab muaj zoo heev corrosion kuj. Nws yog cov khoom siv caij nplooj ntoos hlav uas tuaj yeem sib tw nrog cov hlau.
Raws li Cu Ni alloy, tooj liab dawb muaj kev tiv thaiv zoo heev thiab kev ua haujlwm siab, yog li nws tuaj yeem siv los ua cov khoom siv rau cov khoom siv thiab cov resistors ua haujlwm nyob rau hauv hnyav corrosion.
tooj dag muaj zinc thiab me me ntawm tin, txhuas, txhuas, thiab lwm yam.
