Mutungamiri ndiyo inowanzoshandiswa inyanzvi inoshandiswa mumhangura nekuda kwekukwanisa kwayo kuita kuti mhirizhonga isanyanya kuchinjwa. Shanduro dzakasununguka dzendarira uye dzisina kushandiswa mabhandi, dzakadai seC36000 neC38500, dzinosvika pakati pe2,5% ne4,5% mutungamiri uye dzine huni hwakanaka hwekuumba zvinhu.
Eco Brass® (C87850 uye C69300) ndiyo nzira isina kutungamirira isina kushandisa iyo inoshandisa silicon muchinzvimbo chekutungamirira kuti iwedzere kuchinjwa.
Chikamu chendarira chine chikamu chiduku chealuminium , ichichipa chikara chendarama chakajeka. Mari yeUnited 10, 20 ne50 yepenti yakagadzirwa nechikamu chendarira, inozivikanwa se "Nordic gold" ine 5% aluminium.
Arsenical brasses yakadai seC26130, hazvishamisi, ine arsenic. Zviduku zve arsenic zvinobatsira kudzivisa kupisa kwesimbi.
Tin inoshandiswawo kuwedzera kukonzera kusagadzikana mune dzimwe shasha (semuenzaniso C43500), kunyanya kuderedza zvinoitika zve dezincification.
Manganese shavha (C86300 neC675) inogonawo kuenzaniswa seyendarira yemhangura uye ine simba rakasimba renhengo ine kunaka kwekusimudzira kuputika uye kushungurudza zvinhu.
Nickel ine nhoroondo yakareba yekuve yakashongedzwa nemhangura, zvichida nekuti inobereka sirivha yakaisvonaka, yakashata inogadziriswa simbi. 'Nickel sirivha' (ASTM B122) sezvinowanzobudiswa izvi zvinyorwa, asi hazvirevi sirivha , asi zvinoumbwa nemhangura, zinc, uye nickel.
Iyo yeBritain imwe pound yemari inogadzirwa kubva kuNickel sirivha ine 70% yendarira, 24.5% zinc, uye 5.5% nickel.
Pakupedzisira, simbi inogonawo kuiswa mune zviduku zvishoma kuti iwedzere simba nekuoma kwemhangura. Dzimwe nguva dzinonzi Aich's metal - rudzi rwepfuti simbi-dzakadai sendarira dzave dzichishandiswa mumashandisirwo emvura.
Chati iri pasi apa inopfupikisa zvinowirirana zvendarira zvinowedzera uye zvinhu zvavanobatsira.
