QAL10-4-4 Nickel Aluminium Bronze (ZCuAl10Fe4Ni4) Cov yam ntxwv thiab muaj pes tsawg leeg
QAL10-4-4 aluminium bronze, tseem hu ua ZCuAl10Fe4Ni4, yog ib qho txhuas bronze uas muaj hlau thiab npib tsib xee. Nws muaj cov khoom siv kho tshuab ruaj khov ntawm qhov kub siab ntawm 400 degree thiab yog lub zog kub-resistant bronze. Vim qhov sib ntxiv ntawm npib tsib xee, nws muaj kev tiv thaiv zoo heev thiab nws muaj kev ua haujlwm zoo ntawm kev ua haujlwm, kev ua haujlwm zoo zawv zawg thiab kev ua haujlwm tiv thaiv cavitation, thiab muaj kev sib txhuam zoo. Nws muaj qhov zoo corrosion kuj nyob rau hauv cov huab cua, dej tshiab thiab dej hiav txwv. Nws muaj kev ua haujlwm zoo nyob rau hauv cov xwm txheej kub thiab tuaj yeem ua kom muaj zog los ntawm kev kho cua sov. Nws tuaj yeem welded, tsis yooj yim rau vuam, thiab muaj kev ua haujlwm zoo.
