Kev faib tawm ntawm tooj liab alloys thiab lawv daim ntawv thov
Feem ntau siv tooj liab alloys muab faib ua peb pawg: tooj dag, tooj liab thiab cupronickel
Nws cov nta yog raws li nram no:
1) tooj dag yog tooj liab alloy nrog zinc ua lub ntsiab additives, uas muaj ib tug zoo nkauj daj xim thiab yog collectively hu ua tooj dag. Copper-zinc binary alloy yog hu ua tooj dag zoo tib yam lossis tsuas yog tooj dag. Brass nrog tus nqi siab dua yog hu ua tooj dag tshwj xeeb lossis tooj dag complex. Brass alloys nrog tsawg dua 36 feem pua zinc, nws yog tsim los ntawm cov khoom siv tshuaj thiab muaj cov khoom ua haujlwm txias. Piv txwv li, tooj dag uas muaj 30 feem pua zinc feem ntau yog siv los ua cov mos txwv, feem ntau hu ua mos txwv casing daj, tooj liab lossis xya caum - peb caug tooj dag. Brass alloys nrog zinc cov ntsiab lus ntawm 36 feem pua thiab 42 feem pua yog tsim los ntawm thiab cov ntsiab lus ruaj khov, uas feem ntau siv yog 40 feem pua zinc ntawm rau caum - plaub caug tooj dag. Txhawm rau txhim kho cov khoom ntawm tooj dag zoo tib yam, lwm cov ntsiab lus feem ntau tau ntxiv, xws li txhuas, npib tsib xee, manganese, tin, silicon, txhuas, thiab lwm yam.
Aluminium tuaj yeem txhim kho lub zog, hardness thiab corrosion kuj ntawm tooj dag, tab sis txo cov yas, yog li nws yog tsim rau marine condenser kav thiab lwm yam corrosion-cov khoom tiv thaiv, uas tuaj yeem txhim kho kev ua haujlwm ntawm tooj dag; qhov no pub dawb- txiav tooj dag feem ntau yog siv los ua cov khoom saib. Brass castings feem ntau yog siv los ua li qub thiab cov khoom siv yeeb nkab, thiab lwm yam. Cov hluav taws kub hydrant tawg -cov ntaub ntawv pov thawj crescent wrench feem ntau siv hauv nkoj yog nrum los ntawm tooj dag thiab txhuas.
2) Bronze Ameslikas hais txog tooj liab- tin alloy, thiab tom qab tooj liab alloys tshwj tsis yog tooj dag thiab cupronickel hu ua tooj liab, tin bronze muaj cov khoom zoo casting, tiv thaiv - cov khoom sib txhuam thiab cov khoom siv zoo, thiab tsim nyog. rau kev tsim cov bearings, cab iav, iav, thiab lwm yam. Lead bronze yog ib tug dav siv bearing khoom rau niaj hnub cav thiab grinders. Aluminium bronze muaj lub zog siab, hnav tsis kam thiab zoo corrosion kuj, siv rau casting siab -load gears, bushings, marine propellers, etc. Phosphor bronze muaj siab elastic txwv thiab ua hluav taws xob, nws muaj kev ua tau zoo thiab tsim nyog kev tsim cov precision springs thiab hluav taws xob tiv tauj cov ntsiab lus. Beryllium bronze kuj tseem siv los tsim cov cuab yeej uas tsis yog- cov cuab yeej siv hluav taws xob siv hauv cov mines thiab roj depots. Beryllium tooj liab yog supersaturated solid tov tooj liab -raws li alloy nrog zoo mechanical zog, lub cev muaj zog, tshuaj muaj zog thiab corrosion kuj;
Hmoov metallurgy ntau lawm rau tungsten steel, siab carbon steel, siab kub super hard alloy pwm yuav tsum tau galvanic corrosion, vim qhov loj poob ntawm cov electrodes zoo tib yam, qhov ceev yog qeeb, thiab tungsten tooj liab yog cov khoom siv zoo tagnrho. Bending zog Ntau dua los yog sib npaug rau 667Mpa
3) Cupronickel tooj liab alloy nrog npib tsib xee ua lub ntsiab additive. tooj liab-nickel binary alloy hu ua dog dig cupronickel; ntxiv rau manganese, hlau, zinc, aluminium
Lub cupronickel alloy ntawm lwm cov ntsiab lus hu ua complex cupronickel. Kev lag luam cupronickel tau muab faib ua ob pawg: cov qauv cupronickel thiab hluav taws xob cupronickel. Cov yam ntxwv ntawm cov qauv cupronickel
Lub ntsiab lus yog tias cov khoom siv kho tshuab thiab corrosion kuj zoo, thiab xim zoo nkauj. Qhov no cupronickel yog dav siv nyob rau hauv kev tsim cov precision machinery, tshuaj machinery thiab marine qauv daim. Hluav taws xob cupronickel feem ntau muaj cov khoom siv thermoelectric zoo. Manganese tooj liab, constantan thiab kuaj tooj liab yog manganese dawb tooj liab nrog cov ntsiab lus manganese sib txawv, uas yog cov khoom siv rau cov khoom siv hluav taws xob, varistors, precision resistors, strain gauges, thermocouples, thiab lwm yam.
