Kev ua tau zoo thiab cov yam ntxwv ntawm txhuas bronze 9-4 bearings
Cov kev ua tau zoo thiab cov yam ntxwv ntawm aluminium bronze 9-4 bearings yog: cov khoom siv siab zoo, zoo hnav tsis kam nyob rau hauv cov huab cua, dej tshiab thiab dej hiav txwv, kev ua haujlwm zoo casting, huab cua nruj, hnav tsis kam, tsis yooj yim rau braze, thiab zoo casting kev ua tau zoo.
Cov ntawv thov tseem ceeb: tseem ceeb castings uas xav tau lub zog siab thiab zoo corrosion kuj. Nws yog ib qho ntawm cov ntaub ntawv tseem ceeb rau kev tsim cov nkoj propellers. Nws tseem tuaj yeem siv los ua qhov hnav-tiv taus thiab ua haujlwm hauv qab 400 degree.
Cov yam ntxwv thiab daim ntawv thov ntawm txhuas bronze 9-4 tooj liab bearings: Nws yog cov hlau uas muaj txhuas bronze nrog lub zog siab thiab kev sib txhuam txo, zoo corrosion kuj, zoo siab ua nyob rau hauv kub lub xeev, hluav taws xob vuam thiab roj welding, tab sis tsis zoo brazing. kev ua tau zoo. QAl9-4 txhuas bronze tuaj yeem siv los hloov cov hlau tin hnav-resistant bronze.
