Thaum tshav kub kub muaj zog, muaj kev cuam tshuam siab toughness, tej zaum yuav tsis rhiab rau qhov tsis muaj. Zoo heev thermoplastic, kev kub ceev extrusion mus rau hauv ib tug complex qauv, nyias-walled, hollow profiles ntawm ntau yam, los yog forgings forged rau hauv complex qauv. quenching kub ntau, tsawg quench rhiab heev, tom qab extrusion thiab forging tso tawm, tsuav yog qhov kub siab tshaj qhov kub ntawm quenching, koj tuaj yeem siv dej los yog dej quenching txoj kev. Nyias-walled qhov chaw tseem tuaj yeem nqa tawm cua quenching. Weldability thiab zoo heev corrosion kuj, tsis muaj kev ntxhov siab corrosion cracking nyiam, nyob rau hauv kev kho cua sov yuav tsum tau ntxiv dag zog rau hauv aluminium alloy, Al-Mg-Si raws li alloy tsis yog tsuas yog kev nyuaj siab corrosion cracking tau pom alloy. Txheej txheej yog du heev thiab yooj yim rau anodizing thiab xim. Qhov tsis zoo yog tias tom qab quenching, yog nres rau qee lub sij hawm ntawm chav tsev kub hauv qhov muaj kev cuam tshuam tsis zoo rau kev laus (cov nyhuv nres) muaj zog. Los ntawm txoj kev kos duab casting cov yam ntxwv thiab cov ntsiab lus thermodynamic yog qhov nyuaj kom tsis txhob muaj hydrogen nqus (kub kub dej vapor rau hauv hydrogen thiab oxygen hauv huab cua), txawm hais tias ntau tus kws tshaj lij kev lag luam yog kev siv zog zoo tshaj plaws los tshem tawm cov kua hydrogen cia, tab sis nws nyuaj heev kom muaj. tus nqi ntawm hydrogen yog tsawg tshaj li qhov high-end kev xav tau 0.15cc / 100g ntawm. Tsis tas li ntawd, txij li txoj kev extrusion yog txias extrusion, thiab lub siab yog me me, tsis muaj pa thiab lwm yam txheej txheem, precision ci raj yooj yim ua rau cov npuas npuas.
