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 zoo hnav tsis kam thiab nruj. Paub txog nws qhov tshwj xeeb ua ke ntawm lub zog thiab kev tiv thaiv corrosion, cov hlau no muaj cov ntawv thov hauv ntau qhov 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.
PB1 hom tooj liab 88–89.5%, tin 10-11.5%, phosphorus ~ 0.02%, zoo heev corrosion kuj, zoo hnav tsis kam, siab mechanical zog, zoo hluav taws xob conductivity, haum rau vuam thiab brazing washers, zog, bearings ; Feem ntau haum 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 thauj
PB102 hom tooj liab 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, zoo heev rau brazing thiab vuam ships thiab Marine engineering hardware, hluav taws xob Cheebtsam, fasteners, hniav qhov chaw
SAE660 hom tooj liab 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 Cov dej ntsev thiab dej hiav txwv kuj yog siv nyob rau hauv nruab nrab-lub luag hauj lwm twj tso kua mis thiab valve Cheebtsam, bearings thiab bushings.
