Ndi kupita patsogolo kwa sayansi ya zinthu, ma brass rods akupita patsogolo kuti azigwira bwino ntchito-zophatikizana zambiri. Mwachitsanzo,-zinc mkuwa wambiri (womwe zili ndi zinki zopitirira 40%) umapangitsa kuti usachite dzimbiri powonjezera zinthu monga faifi tambala ndi aluminiyamu, kuti ukhale wolimba pamene ukuupanga kukhala woyenera malo okhwima a mafakitale. Kuwongolera zachilengedwe-kopanda brass (monga HWCuZn{7}}1), kudzera muukadaulo wa microalloying, sikulowa m'malo mwa lead wakale-kumakhala ndi mkuwa komanso kumagwira ntchito bwino kwambiri, kumakwaniritsa zofunikira pachitetezo cha chilengedwe cha zamagetsi ndi zamagetsi. Kuphatikiza apo, zinthu zophatikizika za mkuwa{{10}(monga brass-graphite composite rods) zimachepetsanso kugundana mwa kuwonjezera gawo lopaka mafuta, kusonyeza kuthekera kogwiritsa ntchito pazovala zapamwamba monga ma bearing ndi seal.
