Hamwe niterambere ryibikoresho siyanse, inkoni zumuringa ziratera imbere zigana kumikorere yo hejuru kandi byinshi - guhuza ibikorwa. Kurugero, hejuru - umuringa wa zinc (hamwe na zinc irimo hejuru ya 40%) byongera imbaraga zo kurwanya ruswa wongeyeho ibintu nka nikel na aluminium, bikomeza imbaraga zabyo mugihe bikwiranye n’inganda zikarishye. Ibidukikije byangiza ibidukikije - umuringa wubusa (nka HWCuZn - 1), hifashishijwe ikoranabuhanga rya microalloying, ntirisimbuza isasu gakondo - ririmo imiringa gusa ahubwo rikomeza no gukora imashini nziza, ryujuje ibisabwa byo kurengera ibidukikije bya elegitoroniki n’inganda zikoresha amashanyarazi. Byongeye kandi, imiringa - ishingiye ku bikoresho (nk'umuringa - grafite compite ya compte) irusheho kugabanya coefficient de fraisation wongeyeho icyiciro cyo gusiga, byerekana ubushobozi bwo gukoreshwa mubintu byambaye cyane nko kwifata hamwe na kashe.
