I-ALLOY 20 iyingxubevange eguquguqukayo eyaziwa ngokumelana kwayo nokugqwala okukhethekile ezindaweni eziningi ezigqwalile. Ihlanganiswe ngokuyinhloko nge-nickel, i-chromium, ne-molybdenum, i-ALLOY 20 ibonisa ukumelana okuphezulu ne-sulfuric acid, i-phosphoric acid, i-chlorides, namanye amakhemikhali anolaka. Le alloy ivame ukusetshenziswa ezimbonini ezifana nokucubungula amakhemikhali, ezemithi, ukucubungula ukudla, kanye nezinhlelo zokusebenza zasolwandle lapho ukumelana nama-acids kanye nemithombo yezindaba ebolayo kubaluleke kakhulu. Ngezakhiwo zayo ezinhle kakhulu zemishini nokushisela, i-ALLOY 20 inikeza ukwethembeka nokuqina ezindaweni eziyinselele, ikwenze kube ukukhetha okuhle kwezinhlelo zokusebenza ezibucayi ezidinga ukumelana nokugqwala nokuphila isikhathi eside.
