tooj dag thiab liab tooj liab uas hardness siab?

Toojmuaj hluav taws xob zoo conductivity, thermal conductivity thiab ductility, thiab lwm yam, yog dav siv nyob rau hauv cables thiab hluav taws xob thiab hluav taws xob Cheebtsam, vim nws tsis tshua muaj melting point, yooj yim rau remelt, resmelting, kuj yog ib tug kuj ib puag ncig tus phooj ywg khoom. Feem ntau siv yog tooj dag thiab tooj liab.
tooj dag thiab liab tooj liab uas hardness siab?
1. Lub universal yam ntxwv ntawm cov ntaub ntawv hlau yog hais tias lub hardness ntawm ntshiab hlau yog tsawg tshaj li ntawm nws alloy, uas muaj siab hardness thiab tsawg melting point. Thiab anaerobic tooj liab thiab tooj liab yog tooj liab ntshiab, tab sis qhov purity yog txawv, purity ntawm anaerobic tooj liab yog siab dua, purity ntawm tooj liab muaj peev xwm ncav cuag 99.9% ~ 99.99% (qee qhov sib txawv ntawm cov hom sib txawv) tooj liab muaj tsawg impurities, yog li lub purity ntawm anaerobic copper yog qhov siab tshaj plaws, tab sis qhov siab tshaj plaws ntawm anaerobic cop. anaerobic tooj liab), tooj dag yog qhov nyuaj tshaj plaws.
2. Copper muaj cov yam ntxwv, yuav soften hardness tom qab kev kho cua sov, thiab tom qab lub txias ua hauj lwm yuav harden (txias ua hauj lwm hardening), txij li thaum lub hardness ntawm non-ferrous hlau thiab alloy thiab cuam tshuam los ntawm cov muaj pes tsawg leeg, nameplate, impurities, thiab nrog lub xeev thiab lattice qauv, muaj ntau yam ua, yog li feem ntau muaj ob peb yam hardness cov ntaub ntawv, tsuas yog qualitative piav qhia.
3. Dab tsi yog qhov hardness ntawm ntshav tooj liab? Tooj liab, ntom (7.83g / cm3) melting point 1083 degrees, tooj liab cov ntsiab lus mus txog 99.9%, nws tsis yog magnetic. Nrog zoo hluav taws xob conductivity, thermal conductivity thiab corrosion kuj, tooj liab yog lub npe rau nws purplish liab xim. Tooj liab muaj qhov zoo corrosion kuj nyob rau hauv huab cua, dej hiav txwv thiab ib co non-oxidizing acid, alkali, ntsev tov thiab ntau yam organic acids. Nws yog siv hauv kev lag luam chemical.
