Lub alloy muaj kwv yees li 2% beryllium, muab nws superior corrosion kuj piv rau lwm yam tooj liab alloys. Qhov no ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau cov ntawv thov uas yuav raug rau cov tshuaj hnyav. Tsis tas li ntawd, beryllium tooj liab 172 yog resistant rau hydrogen embrittlement, uas yuav ua rau tsis ua hauj lwm nyob rau hauv lwm yam ntaub ntawv thaum raug hydrogen ntawm high pressures thiab kub.

Beryllium tooj liab 172muaj ib tug impressive ntau yam ntawm lub cev muaj zog. Nws muaj lub siab elastic txwv, zoo heev hnav tsis kam, thiab toughness. Nws lub zog tensile siab ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau kev ua tau zoo nyob rau hauv cov xwm txheej hnyav, xws li roj rigs thiab drilling platforms. Ntxiv thiab,UNS C17200Tsawg thermal expansion ua rau nws haum rau siv nyob rau hauv aerospace daim ntaub ntawv xws li aircraft cav.
Covalloy 172tuaj yeem tiv taus cov khoom hnyav vim nws lub zog siab tawm los thiab cuam tshuam toughness. Nws kuj boasts zoo heev qaug zog tiv thaiv, tso cai rau nws mus tiv thaiv cyclic loading yam tsis tas deformation los yog tsis ua hauj lwm. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom uas xav tau kev ua haujlwm zoo ib yam nyob rau lub sijhawm ntev, xws li cov springs lossis fasteners siv nyob rau hauv qhov chaw huab cua xws li aerospace lossis automotive manufacturing nroj tsuag.
Ntxiv beryllium muab cov alloy superior corrosion kuj piv rau lwm yamUNS C17200, ua kom nws haum rau siv hauv marine daim ntaub ntawv los yog ib puag ncig uas raug rau cov dej ntsev tej zaum yuav muaj kev txhawj xeeb. Tsis tas li ntawd, qhov tsis muaj cov ntsiab lus hlau txhais tau hais tias beryllium tooj liab 172 tsis raug kev txom nyem los ntawm galvanic corrosion thaum raug cov hlau tsis sib xws xws li stainless hlau thiab txhuas uas tuaj yeem ua rau tsis ua hauj lwm ntxov hauv lwm cov ntaub ntawv thaum raug cov xwm txheej zoo sib xws.
Beryllium tooj liab 172tuaj yeem kho cua sov siv ntau txoj hauv kev, suav nrog kev kho cua sov thiab kev kho kev laus. Cov no pab ua kom muaj zog tshaj plaws thaum tswj cov qib ductility thoob plaws tag nrho cov kev pabcuam lub neej, ua rau nws tsim nyog rau cov khoom uas yuav tsum tau ua kom nruj nruj los yog cov duab zoo sib xws. Ntxiv thiab,beryllium tooj liabC17200 muaj qhov tshwj xeeb kub tsis kam mus txog 800 degree (1472 degree F). Qhov no ua rau nws zoo tagnrho rau kev siv vuam lossis vuam, xws li cov khoom siv hluav taws xob lossis cov tshuab hluav taws xob hauv tsheb, qhov twg cov ntaub ntawv raug ua tsis tiav vim qhov kub ntau dhau thaum lub sijhawm ua haujlwm.
