Copper busbars muaj zog tiv thaiv deformation thiab yooj yim rau kev tsim. Thawj xim ntawm tooj liab yog txiv kab ntxwv - daj lossis sawv - liab, tab sis thaum raug huab cua, nws yooj yim oxidizes rau ntshav, li no lub npe "liab tooj liab busbar." Brass busbars, tooj liab-zinc alloy, muaj npe rau lawv cov xim daj. Brass busbars yog qhov zoo nkauj, muaj hluav taws xob zoo thiab thermal conductivity, zoo txhua yam khoom, zoo corrosion kuj nyob rau hauv dej tshiab, dej hiav txwv, thiab cua, yog ib qho yooj yim mus txiav thiab polish, muaj zoo weldability, thiab yog tus nqi tsim nyog. Lawv tau siv dav hauv kev tsim cov khoom siv hluav taws xob, thermally conductive, thiab elastic Cheebtsam, kho vajtse, thiab cov ntaub ntawv zoo nkauj. Hauv cov txheej txheem uas tsis yog - machining txheej txheem, tooj dag busbars feem ntau zoo tshaj rau tooj liab busbars.
Cov hluav taws xob thiab thermal conductivity ntawm tooj dag busbars tsis zoo li ntawm tooj liab hlau. Nyob rau hauv cov nqe lus ntawm hardness, tooj liab busbars yog tsawg zog tshaj tooj liab hlau. Ob qho tib si tooj liab thiab ntshav tooj liab busbars muaj lawv qhov zoo thiab qhov tsis zoo, tab sis lawv lub zog kuj txawv, cuam tshuam rau tib neeg lub neej los ntawm lawv cov kev siv sib txawv.
tooj dag thiab ntshav tooj liab tuaj ntawm cov xim sib txawv thiab zoo. Qhov sib txawv ntawm cov xim yog tam sim ntawd pom tseeb. Nws yog ib qho nyuaj tshaj li tooj dag, thiab lawv qhov hnyav zoo sib xws. Ntshiab tooj liab, tseem hu ua liab tooj liab, muaj qhov ceev ntawm 7.83 g / cm³ thiab melting point ntawm 1083 degrees Celsius. Nws muaj cov khoom siv hluav taws xob zoo heev thiab thermal conductivity, thiab zoo heev corrosion kuj. tooj dag, nrog rau qhov ceev ntawm 8.93 g / cm³, yog siv rau txhua yam tes tsho. Brass yog hnav ntau dua- tiv taus ntau dua li tooj liab ntshiab.
