Aluminium Alloys
Aluminium alloys yog ib hom hlau alloy dav siv nyob rau hauv teb xws li aerospace, automotive, kev tsim kho, thiab kev sib txuas lus vim lub teeb yuag thiab corrosion resistant xwm ntawm txhuas.
Muaj ntau hom aluminium alloys thiab raws li lub npe qhia cov hlau tseem ceeb yog cov ntshiab txhuas (Al), nrog rau kev sib ntxiv ntawm lwm cov alloying ntsiab xws li silicone (Si), tooj liab (Cu), manganese (Mn), magnesium (Mg), Nickel (Ni), Zinc (Zn) los txhim kho nws cov khoom hlau xws li lub zog thiab corrosion kuj. Peb txheej txheem aluminium nrog txias chamber tuag casting, yog li cov aluminium alloy peb siv kuj hu ua cam khwb cia txhuas. Piv nrog rau cov qauv txhuas, cam khwb cia txhuas yog tsim los ua kua dej ntau dua thaum nyob hauv lub xeev molten, tso cai rau cov casting ntawm qhov chaw thiab cov khoom siv nrog qhov ntev. Yog tias koj xav tau lub teeb yuag thiab kav ntev hauv ib feem uas xav tau ntau lawm, aluminium yog ib qho kev xaiv zoo.
Thaum ua raws li cov ntshiab aluminium, aluminium alloy yog ib qho alloy nrog ntau lub ntsiab lus. Silicon (Si) yog feem ntau siv alloying hlau rau txhuas alloys. Nws drastic txhim kho cov fluidity ntawm cov hlau thaum lub sij hawm casting thiab txo qhov tsis xws luag xws li shrinkage kab noj hniav thiab cov kab nrib pleb ntawm qhov kawg. Copper (Cu) yog ntxiv los ntxiv dag zog rau ib feem, nrog rau kev txhim kho nws cov cua sov thiab lub zog nyob rau hauv qhov kub thiab txias. Tab sis poob ib co kuj tiv thaiv corrosion. Manganese (Mn) yog ntxiv los txhim kho corrosion kuj, optimizes qhov sib npaug ntawm lub zog thiab plasticity, txhim kho stamping formability. Magnesium (Mg) boosts lub zog tensile thiab toughness. Nickel (Ni) zoo heev txhim kho cov cua sov thiab lub zog nyob rau hauv qhov kub thiab txias, thiab tiv thaiv cov txhuas los ntawm softening nyob rau hauv qhov kub thiab txias ntawm tus nqi ntawm ib co plasticity thiab corrosion kuj. Zinc (Zn) ua ke nrog txhuas thiab magnesium ua rau kom cov alloys muaj zog thiab hardness nrog ib tug me ntsis txo nyob rau hauv plasticity thiab weldability.
Cov qib tshwj xeeb thiab qib sib npaug thoob ntiaj teb peb siv tau teev tseg hauv qab no, thov nco ntsoov tias cov tshuaj lom neeg tseem ceeb ua raws li GB / T cov qauv.
