Nickel plated zinc (Ni-Zn) hydraulic fittings yog sai hloov cov tsoos trivalent chromium dawb zinc fittings vim lawv qhov zoo. Piv rau cov tsoos dawb zinc haum, Ni-Zn fittings muaj superior corrosion kuj, superior ntsev tsuag kuj thiab superior hardness. Qhov no ua rau lawv muaj peev xwm tiv taus qhov kub thiab txias ntau dua rau kev puas tsuaj los ntawm kev puas tsuaj thiab tshuaj lom neeg ib puag ncig. Tsis tas li ntawd, lawv tau txhim kho hluav taws xob conductivity, uas ua rau lawv tshwj xeeb tshaj yog haum rau cov khoom siv hluav taws xob hydraulic. Thaum kawg, Ni-Zn fittings muaj ntau tus phooj ywg ib puag ncig vim qhov tseeb tias lawv tsis muaj cov organic sib txuas, tsis zoo li cov tsoos dawb zinc fittings.
