Cov yam ntxwv thiab kev siv ntawm ntau yam phosphor bronzes
Phosphor bronze yog tooj liab alloy uas sib txuas cov tin thiab phosphorus los txhim kho nws cov khoom. Qhov sib ntxiv ntawm tin pab txhim kho corrosion kuj thiab lub zog, thaum phosphorus muab kev hnav zoo thiab tawv. Cov alloy no paub txog nws qhov tshwj xeeb ua ke ntawm lub zog thiab kev tiv thaiv corrosion thiab muaj kev siv ntau hauv kev lag luam vim nws cov khoom tshwj xeeb. Phosphor bronze muaj qhov nqaim qis dua (11-20% IACS) dua li tooj dag (28-56% IACS). Txawm li cas los xij, muaj qee qhov kev zam uas qhia tau hais tias muaj zog dua.
Hom PB1 Copper 88–89.5%, Tin 10–11.5%, Phosphorus ~ 0.02% Zoo corrosion kuj, zoo hnav tsis kam, siab txhua yam muaj zog, zoo hluav taws xob conductivity, haum rau vuam thiab brazing Washers, zog, bearings; zoo tshaj plaws rau nruab nrab mus rau siab loads
Hom PB2 Copper 85–87%, Tin 11–13%, Lead ~ 9%, Phosphorus ~ 0.02% Kev tiv thaiv corrosion siab dua, hnav tsis kam, zoo dua qaug zog zoo ib yam li cov ntawv thov rau PB1, nrog kev hnav siab dua thiab loads
Hom PB102 Copper 95%, Tin 4.5–5.5%, Phosphorus 0.2–0.4% Zoo corrosion kuj, txhim kho hnav tsis kam, nruj thiab txhua yam muaj zog; haum rau kev sib sau txias, zoo weldability, heev haum rau brazing thiab vuam Marine thiab offshore hardware, hluav taws xob Cheebtsam, fasteners, hniav qhov chaw
Hom SAE660 Copper 78–82%, Tin 6–8%, Lead 6–8%, Phosphorus ~ 0.02% Zoo hardness, hnav tsis kam, lub zog, zoo heev los tiv thaiv kev sib txhuam thiab machinability; tsis raug kev txom nyem los ntawm dezincification; zoo tiv thaiv dej ntsev thiab dej hiav txwv Siv rau nruab nrab-loaded twj tso kua mis thiab valve Cheebtsam, bearings thiab bushings.
