Kev sib piv ntawm H62 tooj dag bushing thiab phosphor bronze bushing
Cov yam ntxwv tseem ceeb ntawm H62 lub tes tsho tooj liab: H62 lub tes tsho tooj liab yog ib qho ntawm cov hlau tsis muaj hlau ua, thiab nws muaj kev ua haujlwm zoo. H62 lub tes tsho tooj liab yog ib qho yooj yim los txiav tooj dag, thiab muaj ob hom: ib puag ncig tus phooj ywg tooj dag thiab lub tes tsho tooj dag zoo tib yam. Feem ntau, cov qhabnias 58-3 lub tes tsho tooj liab thiab 59-1 lub tes tsho tooj liab yog extruded. Lub tes tsho tooj liab uas tsim los ntawm cov tes tsho tooj liab txuas ntxiv tsis tuaj yeem ua tiav txhua qhov kev ua tau zoo. Lub tes tsho tooj liab ua los ntawm cov txheej txheem extrusion muaj lub zog tensile zoo, siab hardness thiab siab ncaj. H62 lub tes tsho tooj liab kuj muaj cov khoom siv zoo, zoo plasticity hauv lub xeev kub, siv tau plasticity hauv lub xeev txias, zoo machinability, yooj yim brazing thiab vuam, corrosion kuj, tab sis yooj yim los tsim corrosion cracking, ntxiv rau, tus nqi pheej yig, thiab nws yog ib hom tooj dag ntau yam nrog kev siv dav.
Cov yam ntxwv tseem ceeb ntawm phosphor bronze tooj liab tes tsho: phosphor bronze tooj liab tes tsho yog ib lub tes tsho tooj liab. phosphor bronze yog ua los ntawm bronze nrog degassing tus neeg sawv cev, phosphorus P ntsiab lus ntawm {{0}}.03 ~ 0.35%, tin ntsiab lus ntawm 5 ~ 8%. Thiab lwm yam kab kawm xws li hlau Fe, zinc Zn, thiab lwm yam, ductility, qaug zog kuj yog qhov zoo, tuaj yeem siv rau cov khoom siv hluav taws xob thiab khoom siv, thiab kev ntseeg siab yog siab dua li cov khoom siv tooj liab dav dav. Lub tes tsho tooj liab yog ib qho ntawm cov hlau tsis muaj hlau ua cov pas nrig nrog kev ua haujlwm zoo thiab kev ua haujlwm siab. Lub phosphor bronze jack reed hard-wired hluav taws xob qauv, tsis muaj kev sib txuas los yog kev sib txhuam, tuaj yeem ua kom muaj kev sib cuag zoo, zoo elasticity, thiab du plugging thiab unplugging. Cov alloy muaj kev ua haujlwm zoo heev thiab kev tsim cov chips, uas tuaj yeem txo lub sijhawm ua haujlwm ntawm qhov chaw. Phosphor bronze yog dav siv nyob rau hauv tooj liab casting, solder thiab lwm yam teb raws li ib tug intermediate alloy, thiab occupies ib tug tseem ceeb qhov chaw nyob rau hauv txoj kev loj hlob ntawm niaj hnub kev lag luam.
