6063 Aluminium Alloy ndeyakaderera-yakagadziriswa al-mg-si nhevedzano kupisa-kurapwa aluminium Alloy. Iyo ine yakanakisa yekubatanidza kuumbwa kuita, yakanaka corrosion kuramba uye yakakwana michina yezvivakwa. Iyo zvakare inoshandiswa zvakanyanya muindasitiri yemotokari nekuda kwekunyora kwayo. Nekuwedzera kweiyo maitiro ezvekuremerwa marererirwo emotokari, kushandiswa kwe6063 Aluminium Alloy Extrussion Zvigadzirwa muindasitiri yemotokari yakawedzera zvakare.
Iyo microstructure uye zvivakwa zvezvinhu zvinobuda zvinokanganiswa nemhedzisiro yakasanganiswa yekuwedzera kukurumidza kumhanya, kupisa kupisa uye kuendesa ratsio. Pakati pavo, iyo yekuwedzera huwandu inonyanya kutsanangurwa neyekuwedzera kumanikidzwa, kugadzirwa kwekubudirira uye michina yekugadzira. Kana iyo Extrussion Ratio idiki, kushatirisa kweiyo defformation idiki uye kugadziridzwa kwechiochi hakusi pachena; Kuwedzera huwandu hwekuwedzera kunogona kunatsa zviyo, kupwanya chikamu chechipiri chechipiri, tora micranture yeyunifomu, uye kuvandudza michero yemubatanidzwa.
