1. Cov hlau nplaum kub kub yog dov ntawm qhov kub siab thiab muaj qhov zoo ductility.
2. Cov hlau nplaum kub kub tuaj yeem muaj qhov tuab dua.
3. Cov hlau nplaum kub kub muaj zog dua.
4. Qhov sib txawv ntawm cov hlau kub dov thiab cov hlau txias dov:
Cov hlau uas dov txias muaj qhov tawv tsawg vim muaj qee qib ntawm kev ua haujlwm tawv, tab sis nws tuaj yeem ua tiav qhov sib piv zoo, thiab tuaj yeem siv rau cov khoom siv caij nplooj ntoos hlav khoov txias thiab lwm yam khoom. Tib lub sijhawm, vim tias qhov taw tes tso zis ze rau lub zog tensile, tsis muaj kev pom ua ntej rau kev phom sij thaum siv, thiab qhov xwm txheej yooj yim tshwm sim thaum lub nra hnyav tshaj qhov tso cai thauj khoom.
1) Lub phaj txias yog dov txias thiab tsis muaj nplai ntawm nws qhov chaw thiab zoo. Cov phaj hlau kub dov yog dov kub, nrog nplai ntawm qhov chaw thiab qhov tuab sib txawv.
2) Cov hlau kub dov muaj qhov tsis zoo thiab qhov du ntawm qhov chaw, thiab nws tus nqi qis dua, thaum cov hlau txias dov muaj qhov ntev thiab tawv zoo, tab sis nws tus nqi siab dua.
3) Cov hlau dov tau muab faib ua cov dov txias thiab cov dov kub, nrog rau qhov kub thiab txias recrystallization ua qhov sib txawv.
4) Kev dov txias: Kev dov txias feem ntau yog siv los tsim cov hlau uas muaj kev kub ceev. Cov hlau dov kub: qhov kub dov kub thiab qhov kub forging
5) Qhov saum npoo ntawm cov hlau kub dov uas tsis muaj electroplating yog xim av tsaus, thaum cov hlau txias dov uas tsis muaj electroplating yog xim grey, uas tuaj yeem paub qhov txawv ntawm qhov du ntawm qhov chaw tom qab electroplating, thiab qhov du ntawm cov hlau txias dov yog siab dua li cov hlau kub dov.
