● Cov yam ntxwv thiab cov peev txheej ntawm daim ntawv thov:
Nws yog ib hom high-strength hard aluminium uas muaj zog los ntawm kev kho cua sov. Nws muaj nruab nrab plasticity nyob rau hauv annealing, tshiab quenching thiab kub tej yam kev mob. Nws muaj qhov zoo ntawm qhov chaw welding. Nws muaj ib tug nyiam tsim intergranular tawg thaum gas vuam thiab argon arc vuam. Lub alloy muaj ib tug nyiam tsim intergranular tawg thaum lub sij hawm quenching thiab argon arc vuam. Lub machinability yog zoo tom qab txias ua hauj lwm hardening, tab sis tsis zoo nyob rau hauv lub xeev annealed. Kev tiv thaiv corrosion tsis siab, thiab cov txheej txheem anodizing thiab pleev xim feem ntau siv, lossis txheej txheej txhuas ntxiv rau saum npoo los txhim kho corrosion.
