IRON
Hlau yog lub ntsiab lus ntau tshaj plaws nyob rau hauv lub ntiaj teb los ntawm huab hwm coj thiab belongs rau cov kev hloov pauv hlau pawg ntawm lub sij hawm lub rooj. Nws yog ib qho ci iab, grey hlau uas xeb nyob rau hauv ntub dej los yog ntub dej. Hlau yog siv los tsim cov hlau alloys, ntxiv rau kev siv ntau yam engineering, kev tsim khoom, thiab kev siv hauv tsev.
NICKEL
Nickel yog cov khoom siv tshuaj lom neeg thiab lwm yam kev hloov pauv hlau los ntawm lub sijhawm teem sijhawm. Nws yog cov hlau silvery uas tuaj yeem tiv taus corrosion ntawm qhov kub thiab txias. Nickel tuaj yeem tsim cov alloys ntxiv thiab feem ntau pom hauv cov roj teeb, npib, armor plating, thiab lwm yam.
COBALT
Cobalt yog cov khoom siv tshuaj lom neeg thiab cov hlau hloov pauv los ntawm lub sijhawm teem sijhawm. Nws yog ib lub silvery-xiav hlau nrog siab corrosion kuj thiab zoo nkauj tsos. Cobalt tuaj yeem siv los tsim cov alloys ntxiv, feem ntau yog siv dav hlau turbine generators, thiab daim duab kos duab, thiab tuaj yeem pab kho mob qog noj ntshav.
STEEL
Hlau yog ib qho hlau alloy ntawm hlau thiab carbon nrog ib tug silver los yog grey xim. Nws yog siv nyob rau hauv ib co ntawm lub ntiaj teb no tseem ceeb tshaj plaws engineering thiab siv cov ntaub ntawv ua tsaug rau nws lub zog thiab endurance.
STAINLESS STEEL
Stainless hlau kuj yog ib qho alloy ntawm hlau thiab carbon nrog ntxiv ntawm chromium thiab npib tsib xee los tsim kev tiv thaiv corrosion. Nws yog resistant rau xeb thiab siv nyob rau hauv ntau industrial, tsev neeg, thiab kev kho mob daim ntawv thov.
GADOLINIUM
Gadolinium yog ib qho mos, nyiaj hlau siv los tsim cov hlau alloys. Nws tuaj yeem pab txhim kho kev ua haujlwm, kub siab, thiab oxidation tsis kam ntawm cov hlau xws li hlau thiab chromium alloys. Nws yog feem ntau siv hauv MRI tshuab thiab nuclear reactors.
DYSPROSIUM
Dysprosium yog ib qho ci ci, nyiaj xim hlau tsis tshua siv los ua cov hlau ntshiab. Nws yog tag nrho resistant rau demagnetization, ua rau nws pab tau nyob rau hauv automotive motors, generators, cua turbines, thiab hluav taws xob tsheb.
