Kupanga deta, kutumiza kunja ndikupereka mitundu yosiyanasiyana ya 70/30 Brass Tubes omwe amagwiritsidwa ntchito m'malo osiyanasiyana.Aloyi yamkuwa ya zinc yokhala ndi malata ndi arsenic pang'ono.Izi zimawonjezedwa ngati inhibitor motsutsana ndi dezincification.Aloyiyo imawonetsa kuphatikizika kwamphamvu ndi ductility ndipo nthawi zambiri imasankhidwa nthawi zonse zikafunika kuzizira kwambiri komanso zotsika mtengo.
70/30 Brass Tubes amagwiritsidwa ntchito makamaka m'makampani a Shuga, Zida ndi General Engineering.
