1, cov hlau muaj cov hlau
-Air (Fe)
Cov yam ntxwv: Qib thib plaub hauv lub ntiaj teb kev ua kaub puab, nws yog qhov pheej yig thiab muaj lub zog siab, thiab muaj zog kom xeb (tsim cov hlau oxide).
Kev Siv: Kev Tsim (Hlau), Mechanical Manufacturing, feem ntau txhim kho kev ua tau zoo los ntawm kev ua alloy (xws li stainless hlau).
-Aluminum (al)
Nta: lub teeb yuag (qis ceev), xeb-resistant (fermal zaj duab xis), muaj zog oxide thiab thermal ua ke tab sis zoo li aluminium alloy).
Kev siv: Aviation, ntim (poom), khoom siv hluav taws xob.
-Cov khoom (CU)
Nta: Zoo heev hluav taws xob thiab thermal delityity, corrosion tsis kam, zoo ductility, thiab tus nqi siab.
Kev siv: cov xov hlau, cov hluav taws xob hauv hluav taws xob, cov raj hluav taws xob (tooj liab (tooj dag \/ tooj liab \/ tooj liab yog cov siv ntau).
-Zinc (Zn)
Nta: corrosion resistance (rau galvanized steel), qis melting point, siab britleness ntawm chav tsev kub.
Kev siv: Roj teeb, tiv thaiv cov txheej txheej corrosion.
2, Muaj zog loj \/ tshwj xeeb hom phiaj
-Titanium (ti)
Nta: Muaj zog rau qhov hnyav piv, corrosion kuj (tshwj xeeb tshaj yog nyob rau hauv hiav txwv \/ acidic \/ alkaline ib puag ncig), biolompatibility.
Kev siv: Aerospace, kev cog phom kev kho mob.
Magnesium (mg)
Cov yam ntxwv: lub teeb pom kev zoo tshaj plaws hlau hlau, nplaim taws (hmoov lossis ntawv lossis cov ntawv), lub zog qis yuav tsum muaj kev sib dhos.
Kev siv: automotive lub teeb yuag, 3C protages khoom.
-Tungsten (w)
Nta: siab tshaj plaws melting taw tes (3422 degree c), siab ntom, siab brittleness.
Kev Siv: Lub Teeb Noob Plaub Hau, Armor Piercing batat, cov cuab yeej kub.
3, Lwm cov hlau tseem ceeb
-Nickel (NI): Kev kub siab \/ kub siab \/ corrosion resistant, siv rau cov hlau stainless thiab roj teeb (npib tsib xee thiab hydrogen).
-Qhov (PB): qhov ceev) siab, hluav taws xob tiv thaiv, tab sis lom, siv hauv cov roj teeb thiab cov khoom tiv thaiv.
-Tin (SN): Tsawg melting taw tes, tsis-lom, siv rau soldering thiab zaub mov ntim (tinplate).
