| 101 Tooj | 37,000 psi (1/2 nyuaj) | 14% | Rockwell F60 | 0.323 lbs/cu. hauv. | 500 ° F |
Cov ntaub ntawv dav dav rau tooj liab
Tag nrho cov tooj liab alloys tiv thaiv corrosion los ntawm dej tshiab thiab chav. Nyob rau hauv feem ntau nyob deb nroog, marine thiab industrial atmospheres tooj liab alloys kuj resistant rau corrosion. Tooj liab yog resistant rau saline daws, av, non-oxidising minerals, organic acids thiab caustic daws. Moist ammonia, halogens, sulphides, kev daws teeb meem uas muaj ammonia ions thiab oxidising acids, zoo li nitric acid, yuav tua tooj liab. Copper alloys kuj muaj qhov tsis zoo rau cov inorganic acids.
Kev tiv thaiv corrosion ntawm tooj liab alloys los ntawm kev tsim cov yeeb yaj kiab adherent ntawm cov khoom nto. Cov yeeb yaj kiab no kuj tsis zoo rau corrosion yog li tiv thaiv lub hauv paus hlau los ntawm kev tawm tsam ntxiv.
Copper npib tsib xee alloys, txhuas tooj dag, thiab txhuas bronzes qhia superior tiv thaiv dej ntsev corrosion.
Hluav taws xob conductivity
Cov hluav taws xob conductivity ntawm tooj liab yog thib ob tsuas yog nyiaj. Cov conductivity ntawm tooj liab yog 97% ntawm cov conductivity ntawm Silver. Vim nws cov nqi qis dua thiab ntau dua, tooj liab tau ib txwm ua cov khoom siv hluav taws xob siv rau kev siv hluav taws xob.
Txawm li cas los xij, kev txiav txim siab hnyav txhais tau hais tias feem ntau ntawm cov nyiaj siv ua haujlwm siab hluav taws xob tam sim no siv txhuas ntau dua li tooj liab. Los ntawm qhov hnyav, qhov conductivity ntawm txhuas yog nyob ib ncig ntawm ob npaug ntawm tooj liab. Cov aluminium alloys siv tsis muaj zog thiab yuav tsum tau ntxiv dag zog nrog galvanized lossis aluminium coated high tensile steel hlau hauv txhua txoj hlua.
Txawm hais tias ntxiv ntawm lwm cov ntsiab lus yuav txhim kho cov khoom zoo li lub zog, yuav muaj qee qhov poob hauv hluav taws xob conductivity. Raws li piv txwv li 1% ntxiv ntawm cadmium tuaj yeem ua kom muaj zog los ntawm 50%. Txawm li cas los xij, qhov no yuav ua rau txo qis hauv hluav taws xob conductivity ntawm 15%.
