Lub hardness ua ntej quenching yog 200-250HV, thiab hardness tom qab quenching yog ≥36-42HRC.
Beryllium tooj liab yog ib qho hlau uas muaj cov khoom siv zoo, lub cev thiab tshuaj lom neeg.Tom qab quenching thiab tempering, nws muaj lub zog siab, elasticity, hnav tsis kam, qaug zog thiab kub ua haujlwm.Nyob rau tib lub sij hawm, beryllium tooj liab kuj muaj hluav taws xob conductivity.High thermal conductivity, txias tsis kam thiab tsis-sib nqus, tsis muaj sparks ntawm kev cuam tshuam, yooj yim rau vuam thiab braze, zoo heev corrosion kuj nyob rau hauv huab cua, dej tshiab thiab dej hiav txwv.
Corrosion kuj tus nqi ntawm beryllium tooj liab alloy hauv seawater: (1.1-1.4) × 10-2mm / xyoo.Corrosion qhov tob: (10.9-13.8) × 10-3mm / xyoo.Tom qab corrosion, tsis muaj kev hloov hauv lub zog thiab elongation.
Yog li ntawd, nws tuaj yeem khaws cia hauv dej hiav txwv rau ntau tshaj 40 xyoo, thiab nws yog cov khoom siv tsis tuaj yeem hloov pauv rau cov qauv ntawm submarine cable repeaters.Nyob rau hauv sulfuric acid nruab nrab: nyob rau hauv sulfuric acid nrog ib tug concentration ntawm tsawg tshaj li 80% (chav kub), qhov tob corrosion txhua xyoo yog 0.0012-0.1175mm, thiab corrosion yog me ntsis ceev thaum lub concentration ntau dua 80%.
Lub neej ua haujlwm ntev ntawm beryllium tooj liab pwm: Kev siv nyiaj ntawm cov pwm pwm thiab kev ua haujlwm txuas ntxiv, kev cia siab rau lub neej ntawm pwm yog qhov tseem ceeb heev rau cov tuam txhab.Thaum lub zog thiab hardness ntawm beryllium tooj liab ua tau raws li qhov yuav tsum tau ua, beryllium tooj liab yuav cuam tshuam rau pwm kub.Qhov tsis hnov tsw rau kev ntxhov siab tuaj yeem txhim kho lub neej kev pab cuam ntawm pwm.
Lub zog tawm los, elastic modulus, thermal conductivity thiab kub expansion coefficient ntawm beryllium tooj liab kuj yuav tsum tau txiav txim siab ua ntej txiav txim siab siv cov ntaub ntawv ntawm beryllium tooj liab pwm.Beryllium tooj liab yog ntau tiv taus thermal kev nyuaj siab dua li cov hlau tuag.
Zoo heev nto zoo ntawm beryllium tooj liab: beryllium tooj liab yog heev haum rau nto xov, tuaj yeem ncaj qha electroplated, thiab muaj adhesion zoo heev, thiab beryllium tooj liab kuj yooj yim rau polish.
Beryllium tooj liab muaj zoo thermal conductivity, zoo txhua yam khoom thiab zoo hardness.Nws yog feem ntau siv nyob rau hauv cov cheeb tsam uas qhov kev txhaj tshuaj kub ntawm cov khoom yog siab, nws tsis yooj yim rau siv cov dej txias, thiab cov cua sov yog concentrated, thiab cov khoom yuav tsum tau zoo heev.
