Ukwenziwa kwedatha, ukuthumela ngaphandle kunye nokubonelela ngoluhlu olubanzi lwe-70/30 Brass Tubes ezisetyenziswa kwiindawo ezahlukeneyo.I-alloy ye-zinc yobhedu equkethe i-tin kunye nenani elincinci le-arsenic.Oku kongezwa njenge-inhibitor ngokuchasene ne-dezincification.I-alloy ibonisa indibaniselwano elungileyo yamandla kunye ne-ductility kwaye idla ngokukhethwa nanini na iipropati ezibalaseleyo zokusebenza ezibandayo kunye neendleko eziphantsi kakhulu zinqweneleka.
I-70/30 ye-Brass Tubes isetyenziswa kakhulu kwi-Sugar Industries, i-Amunition and General Engineering.
