C72900 yog Cu15Ni8Sn raws li tooj liab-raws li metastable decomposition-strengthened high-kev ua tau zoo alloy.
* Ua tiav kev sib xyaw ua ke ntawm kev nruj nruj thiab lub zog siab.Muaj peev xwm tiv taus dynamic cuam tshuam loads.Muaj peev xwm ua tau raws li qhov xav tau nruj tshaj plaws ntawm cov khoom siv hluav taws xob zoo li qub thiab siab.
* Kev ua tau zoo ntawm cov kabmob tiv thaiv kev coj tus kheej, nrog rau kev ua tau zoo ntawm lub ntuj tsim nws tus kheej lubrication yam tsis muaj kev sib txhuam ua ke, nws yog ib qho khoom tsim nyog rau kev tsaws iav bearing ntawm cov dav hlau loj, thiab tseem yog qhov kev sib txhuam ntawm cov roj zoo txuas.
* Haum rau txhua yam acidic ib puag ncig lossis dej ntsev, kub kub corrosion kuj.

Hauv kev lag luam roj, CuNiSn alloy kuj tuaj yeem siv rau hauv hydraulic thauj tog rau nkoj, sib txuas ntawm cov pas nrig ntawm cov roj qhov dej, txiav thaum drilling (LWD), bearing bush thiab thrust washer.
