OEM àbhaisteach almain alloy tilgeadh letilgeadh gainmhichagus pròiseasan tilgeadh molltair shligean.
Dh’ fhaodadh alùmanum agus na h-aloidhean aige a bhith air an tilgeadh agus air an dòrtadh le tilgeadh bàs le cuideam àrd, tilgeadh bàs le cuideam ìosal, tilgeadh grabhataidh, tilgeadh gainmhich, tilgeadh tasgaidh agustilgeadh foam air chall. Mar as trice, tha nas lugha de chuideam aig na tilgeadh almain alloy ach structar iom-fhillte agus uachdar nas fheàrr.
Dè an alloy alùmanum a bhios sinn a’ tilgeil le pròiseas tilgeadh gainmhich:
• Cast Aluminium Alloy le Sìona Coitcheann: ZL101, ZL102, ZL104
• Tilg Aluminium Alloy le USA Stardard: ASTM A356, ASTM A413, ASTM A360
• Tilg Aluminium Alloy le Starndards eile: AC3A, AC4A, AC4C, G-AlSi7Mg, G-Al12

Feartan Castings Alloy Alùmanum:
• Tha an coileanadh tilgeadh coltach ri coileanadh tilgeadh stàilinn, ach tha na feartan meacanaigeach coimeasach a’ dol sìos nas motha mar a tha tiugh a’ bhalla a’ dol am meud
• Cha bu chòir do thiugh balla nan tilgeadh a bhith ro mhòr, agus tha feartan structarail eile coltach ris an fheadhainn aig tilgeadh stàilinn
• Cuideam aotrom ach structarail iom-fhillte
• Tha na cosgaisean tilgeadh gach kg de thilgeadh alùmanum nas àirde na cosgaisean tilgeadh iarainn is stàilinn.
• Ma thèid a thoirt a-mach le pròiseas tilgeadh die, bhiodh a’ chosgais molltair agus pàtrain mòran nas àirde na pròiseasan tilgeadh eile. Mar sin, bhiodh tilgeadh alùmanum die tilgeadh nas freagarraiche airson tilgeadh le meud mòr dùbhlanach.
