Cov ntawv cim tooj dag thiab cov ntawv txhuas txhuas feem ntau yog siv rau ntau yam kev lag luam thiab kev siv rau kev sau npe, cim npe, thiab txheeb xyuas ntau yam khoom. Txawm hais tias lawv yuav zoo sib xws hauv qhov tsos, muaj qee qhov sib txawv tseem ceeb ntawm ob.
Qhov txawv tshaj plaw ntawmtooj dagthiab aluminium ntawv yog cov khoom siv.Cov ntawv tooj dagyog tsim los ntawm cov tooj liab thiab zinc alloy, thaum cov ntawv txhuas txhuas yog tsim los ntawm cov ntshiab txhuas.
Ib qho txiaj ntsig tseem ceeb ntawmtooj dagyog lawv durability. Brass yog cov khoom siv ruaj khov uas tuaj yeem tiv taus ib puag ncig hnyav xws li cua sov, txias, thiab noo noo. Yog li ntawd, cov ntawv xov tooj tooj dag feem ntau siv rau hauv cov ntawv thov sab nraum zoov thiab thaj chaw muaj kev lag luam uas muaj kev ruaj ntseg tseem ceeb.
Ntawm qhov tod tes,aluminium ntawvfeem ntau yog siv nyiaj ntau dua li cov ntawv cim tooj dag thiab ua kom yooj yim dua. Lawv kuj yog qhov hnyav dua thiab yog li tsim nyog rau cov ntawv thov qhov hnyav yog qhov kev txhawj xeeb.
Thaum nws los txog qhov tsos,tooj dagmuaj ib tug ntau tsoos thiab elegant saib vim lawv tshwj xeeb golden tiav. Lawv feem ntau siv rau hauv cov ntawv thov uas qhov kev zoo nkauj yog qhov tseem ceeb, xws li cov cim npe zoo nkauj lossis cov ntawv sau rau cov khoom lag luam siab.
Aluminium daim ntawv los, txawm li cas los xij, muaj qhov huv thiab niaj hnub saib vim lawv cov nyiaj zoo nkauj. Lawv feem ntau siv rau hauv kev tsim khoom thiab kev siv hauv kev lag luam uas muaj nuj nqi tseem ceeb tshaj qhov pom.
Hauv cov ntsiab lus, xaiv ntawmtooj dagthiabaluminium ntawvnqes mus rau cov kev cai tshwj xeeb ntawm daim ntawv thov. Yog hais tias durability thiab zoo nkauj yog qhov tseem ceeb,tooj dagtej zaum yuav yog txoj kev mus. Yog tias tus nqi-zoo thiab qhov hnyav yog qhov tseem ceeb,aluminium ntawvtej zaum yuav yog qhov kev xaiv zoo dua.
