Kev faib tawm ntawm Bismuth Alloys

Tin-bismuth alloy
Tin-bismuth alloy yog ib puag ncig tus phooj ywg alloy. Nyob rau hauv chav tsev kub, nws yog khoom thiab silver-dawb nrog lub melting point ntawm 138 degree, ib tug solid-kua ntim shrinkage tus nqi ntawm 0.051 feem pua, thiab muaj zog permeability. Qhov qis melting point tin-bismuth pwm alloy yog siv los ua nyias phaj txias stamping pwm, uas tuaj yeem nias tooj liab, txhuas, hlau, stainless hlau thiab lwm daim hlau, thiab lub thickness ntawm cov hlau phaj tuaj yeem ncav cuag. Rau kev kos duab, khoov thiab tsim cov ntawv nyias. Kev siv cov hlau tsis tshua muaj melting point alloy pwm tsis xav tau pwm hlau, thiab cov yeeb yaj kiab tsim yog yooj yim thiab ceev; pwm tus nqi qis thiab qhov hloov tshiab yog ceev; pwm tsis tas yuav hloov kho, thiab tsis tas yuav tsum tau ua tiav; cov pwm tuaj yeem rov ua dua tom qab siv, thiab cov hlau tuaj yeem siv tau ntau zaus; Zoo heev txo cov pwm stacking qhov chaw.
Lead-bismuth alloy
Lead-bismuth alloys tseem hu ua low-temperature alloys, los yog low-melting-point alloys, los yog fusible alloys. Nws yog tsuas yog tsim los ntawm cov hlau lead thiab bismuth nrog qis melting point, thiab qee cov hlau kuj tau ntxiv los kho qhov melting point ntawm cov hlau. Lead-bismuth alloys tuaj yeem siv los ua cov dej txias rau cov reactors. Txawm hais tias lub melting point ntawm lead-bismuth eutectic alloys (LBE) yog me ntsis siab dua li sodium, nws cov tshuaj lom neeg kev ua si tsis muaj zog. Kev ntsuam xyuas kev ua tau zoo thiab cov kev siv engineering siv tau (nrog rau kev siv hauv mobile nuclear fais fab units) Txhua tus tau ua pov thawj tias nws muaj peev xwm siv tau los ua cov dej txias rau cov tiam tom ntej ntawm cov reactors ceev ceev.
Bismuth aluminium alloy
Cov alloy npaj nrog bismuth thiab txhuas yog siv los ua cov muab tub lim rau qhov nkhaus nyias-walled raj, uas tuaj yeem ua kom cov phab ntsa sab hauv ntawm lub raj du thiab huv, thiab cov muab tub lim tuaj yeem siv tau ntau zaus.
Cov hlau nplaum uas tsis tshua muaj melting point yog tsim los ntawm bismuth thiab cadmium, indium, cadmium thiab silver yog siv los ua cov khoom siv hluav taws xob, fuses, tsis siv neeg ntaus ntawv signalers, thiab lwm yam. Hloov cov mos txwv txhuas nrog bismuth-tin alloy mos txwv.
