Kev hloov pauv ntawm cov hlau rau ntau txoj hauv kev yog hu ua cov txheej txheem kev ua haujlwm, thiab muaj plaub yam tseem ceeb:
(1) Machining kev ua tau zoo: qhia txog qhov nyuaj ntawm kev txiav cov ntaub ntawv hlau nrog cov cuab yeej txiav (xws li tig, milling, npaj, sib tsoo, thiab lwm yam).
(2) Forgeability: Qhia txog qhov nyuaj ntawm kev tsim cov ntaub ntawv hlau thaum lub sijhawm ua haujlwm siab, xws li plasticity ntawm cov khoom rhuab mus rau qhov kub thiab txias (qhia raws li qib ntawm cov yas deformation tsis kam), tso cai rau qhov kub thiab txias ntawm kev kub siab, thermal expansion thiab contraction yam ntxwv thiab txwv tsis pub deformation tseem ceeb ntsig txog microstructure thiab mechanical zog, fluidity ntawm cov hlau zoo li thermal conductivity thiab deformation.
(3) Castability: Xav txog qhov nyuaj ntawm melting thiab casting cov khoom hlau mus rau hauv lub casting, qhia fluidity, aspiration, oxidation, melting point nyob rau hauv lub molten lub xeev, uniformity, compactness, thiab txias shrinkage ntawm lub microstructure ntawm lub casting. Tos.
(4) Solderability: Reflects cov cua kub ceev ntawm cov khoom hlau nyob rau hauv ib cheeb tsam, yog li ntawd lub bonding ib feem yog sai melted los yog semi-melted (yuav tsum tau siab), kom cov bonding qhov chaw yog ruaj khov ua ke los ua tag nrho cov yooj yim, uas yog qhia raws li melting point thiab melting. Cov khoom tau txais, oxidizing cov cuab yeej, thermal conductivity, thermal expansion thiab contraction yam ntxwv, plasticity, thiab kev sib raug zoo nrog microstructure ntawm qhov sib koom ua ke thiab cov khoom nyob ze, thiab lub zog ntawm cov khoom siv kho tshuab.
