Chikonzero chatinosarudza aruminiyamu yekushongedza imhaka yekuti chimiro chayo chakanyanya kugadzikana, uye ine corrosion resistance mukushandiswa kwenguva refu. Nekudaro, mamwe maaruminiyamu profiles anozove nekuora pamusoro, izvo zvinonyanya kukonzerwa nekuumbwa kwezvinhu zvisirizvo panguva yekugadzira.
1. Muchigadziro chekukanda, chikamu che magnesium nesilicon hachina kukodzera, sekuvapo kweimwe silicon yakasara, iyo ine chidimbu chiduku chesilicon muhurumende yakasununguka, ichaita ternary compounds mualuminium alloy panguva imwe chete. Izvi zvisinganyunguriki zvetsvina zvikamu kana mahara ehutsvina nhanho akaumbwa mune alloy anowanzo kuunganidza pamuganhu wezviyo, uye anonetesa simba nekuoma kwemuganhu wezviyo panguva imwe chete, inova iyo isina kusimba link yekudzivirira ngura, uye ngura inotanga kubva ipapo.
2. Muchigadziro chekunyunguduka, kunyange zvazvo chikamu che magnesium nesilicon chiri mukati mehutano, asi dzimwe nguva nekuda kwekusaenzana uye kusina kukwana kusanganiswa, zvichiita kuti kugoverwa kusina kufanana kwesilicon mukunyunguduka, kune nzvimbo dzakapfuma uye nzvimbo dzine urombo. Iyo diki yemahara silicon mualuminium matrix haingoderedze kushora kwekupokana kwealloy, asiwo coarse saizi yezviyo zvealloy.
3. The kudzorwa siyana hwokugadzira parameters panguva extrusion, akadai bhawa preheating tembiricha yakanyanyisa, simbi extrusion kuyerera mwero, mhepo kutonhora simba panguva extrusion, kuchembera tembiricha uye kubata nguva uye zvimwe zvisina kufanira kudzora zviri nyore kubudisa nesilicon segregation uye dissociation, kuitira kuti magnesium uye nesilicon regai zvachose kuva Mg2Si, vamwe vakasununguka nesilicon iripo.
Muchidimbu, kana pamusoro peiyo aluminiyamu profiles iri nyore kuita ngura mukushandiswa, imhaka yekuti chiyero chemhando yealuminium chimiro chakanyanya kuderera mukugadzirwa, saka isu tinofanirwa kuwana nyanzvi yekugadzira pakusarudza iyo aluminium profiles, saka iyo aluminiyumu mbiri yaunosarudza ichave yakachengeteka zvakanyanya.
