Nickel Chrome tiv thaiv alloys
Nichrome, tseem hu ua Nickel Chrome, yog ib qho uas tsim los ntawm kev sib xyaw ntawm npib tsib xee, chromium thiab, hlau. Cov paub zoo tshaj plaws rau nws cov cua sov tsis kam, nrog rau nws txoj kev tiv thaiv thiab oxidation, lub alloy yog pab tau ntau heev rau ntau cov ntawv thov. Los ntawm kev lag luam tsim rau kev ua haujlwm hobby, Nichrome nyob rau hauv daim ntawv ntawm cov hlau yog tam sim no nyob rau hauv ntau cov khoom lag luam, khoom siv tes thiab khoom siv. Nws kuj pom cov ntawv thov hauv cov chaw tshwj xeeb.
Nichrome hlau yog ib qho alloy ua los ntawm npib tsib xee thiab chromium. Nws tiv thaiv kub thiab oxidation thiab pabcuam ua cua sov hauv cov khoom lag luam xws li cov tshuab raj thiab tshuab ziab plaub hau. Hobbyists siv NichRome Hlau hauv Ceramic Duab puab puab thiab iav. Cov hlau tseem tuaj yeem pom nyob hauv lub chaw soj nstuam, tsim kho thiab cov khoom siv hluav taws xob tshwj xeeb.
Vim tias NichRome hlau yog li tiv taus hluav taws xob, nws yog pab tau zoo heev raws li cov cua kub hauv cov khoom lag luam thiab cov cuab yeej hauv tsev. Toasters thiab tshuab ziab plaub hau siv coils ntawm nichrome hlau los tsim cov nyiaj kub loj, ua cua sov thiab tso cua sov. Muaj cov chaw ua kom sov kuj siv nichrome hlau ua haujlwm. Ib qho ntev ntawm nichrome hlau kuj tseem siv tau los tsim cov hlau kub cutter, uas tuaj yeem siv rau hauv tsev lossis hauv kev lag luam teeb tsa thiab ua kom zoo nkauj thiab txhuam.
Nichrome hlau yog ua los ntawm cov xom khwm tsis muaj sib nqus feem ntau ntawm Nickel, chromium, thiab hlau. Nichrome yog tus cwj pwm los ntawm nws cov siab tiv taus thiab zoo oxidation tsis kam. Nichrome hlau kuj muaj ducility zoo tom qab siv thiab zoo heev Veldability.
Tus lej uas los tom qab Nichrome hlau hom qhia qhov feem pua ntawm Nickel hauv cov alloy. Piv txwv li, "Nichrome 60" muaj kwv yees li 60% npib tsib xee nyob rau hauv nws muaj pes tsawg leeg.
Cov ntawv thov rau NichRome hlau suav nrog cov cua sov cov ntsiab lus ntawm cov tshuab plaub hau, cov cua sov, thiab kev txhawb nqa ceramic hauv kilns.
