C19200 yog tooj liab-hlau-phosphorus (Cu-Fe-P) alloy, yog ib tsev neeg ntawm nag lossis daus- tooj liab uas tuaj yeem tsim tau rau cov khoom siv hluav taws xob thiab hluav taws xob. Nws yog muab los ntawm cov sawb thiab daim ntawv, thiab nws puv qhov sib txawv ntawm annealed siab - conductivity tooj liab, uas yog mos heev los tuav lub caij nplooj ntoos hlav hu, thiab lub zog tab sis ntau tsawg conductive tin bronzes thiab npib tsib xee silvers.
Cov Hlau thiab Phosphorus Ua li cas
Hlau muaj tsawg heev solubility nyob rau hauv tooj liab nyob rau hauv lub chav tsev kub tab sis yog ntau soluble nyob rau hauv high kub, thiab phosphorus ua ke nrog hlau los tsim zoo precipitates rau txias los yog nyob rau hauv kev tswj kev laus. Cov precipitates impede dislocation txav, yog li cov alloy ua tiav lub zog siab dua thiab muaj zog zoo dua rau softening dua li tooj liab ntshiab ntawm tib chav kawm conductivity. Vim tias tag nrho qhov sib ntxiv tsuas yog me ntsis tshaj li ib feem pua, kev nplua rau kev coj ua yog nruab nrab, thiab qib tseem yog qhov siab tshaj - cov khoom siv conductivity.
| Element | Cov ntsiab lus | Muaj nuj nqi |
|---|---|---|
| Tooj nrog nyiaj | 99.0% min | Matrix |
| Hlau | 0.8-1.2% | Ua kom muaj zog precipitates |
| Phosphorus | 0.025-0.04% | Deoxidiser thiab precipitate qub |
| Magnesium, hlau | Trace, yeem | Siv nyob rau hauv cov qib uas muaj feem xyuam tsuas yog qhov tau teev tseg |
Sawb, daim ntawv thiab dov bar raug txiav txim rau ASTM B465, uas hais txog cov kev txwv muaj pes tsawg leeg, tus npauj npaim tsim thiab cov cuab yeej cuab tam rau txhua tus npau taws. Cov npe Suav qib rau tooj liab- hlau alloys tshwm nyob rau hauv GB / T 5231, thiab cov Japanese strip designations raug teev nyob rau hauv JIS tooj liab thiab tooj liab alloy strip qauv.
Khoom los ntawm Temper
| Temper pawg | Tensile zog | Tus cwj pwm |
|---|---|---|
| Mos annealed tempers | Txog 280-330 MPa | Qhov siab tshaj plaws elongation, siv rau kev sib sib zog nqus nqus thiab sib sau loj heev |
| Ib nrab - nyuaj thiab nyuaj tempers | Txog 350-430 MPa | Zoo sib npaug ntawm formability thiab caij nplooj ntoos hlav zog |
| Ntxiv - caij nplooj ntoos hlav tempers | mus txog 480 MPa | Lub zog siab tshaj plaws rau kev sib cuag thiab lub caij nplooj ntoos hlav |
Cov txiaj ntsig saum toj no piav qhia cov qhab uas tau them los ntawm tus qauv thoob plaws qhov muag mus rau ntxiv - caij nplooj ntoos hlav tempers; Qhov kev lees paub yam tsawg kawg nkaus rau txhua tus npau taws yog teev nyob rau hauv ASTM B465 thiab rov ua dua ntawm daim ntawv pov thawj zeb. Hluav taws xob conductivity yog siab, nyob rau hauv tib chav kawm ntawv raws li qhov tsawg tshaj plaws -alloyed Cu- Fe- qib P thiab zoo tshaj cov tin bronzes, thiab nws yog teev raws li qhov tsawg kawg nkaus rau lub temper mov.
Kev tiv thaiv kom muag muag yog ib qho laj thawj ntawm kev xaiv cov qib. Cov alloy khaws cov khoom muaj txiaj ntsig zoo rau kwv yees li 350-400 deg C, uas txhais tau tias nws muaj sia nyob cov txheej txheem soldering thiab reflow siv nyob rau hauv connector thiab lead thav duab los ua ke yam tsis muaj kev sib cuag quab yuam.
Thaum tshav kub kub kho thiab hardening txoj kev
C19200 yog hardened los ntawm kev sib xyaw ua haujlwm txias thiab nag lossis daus, tsis yog los ntawm quench-thiab- lub voj voog kub siv rau steel. Kev kho cov tshuaj dissolves hlau thiab phosphorus, txias dov tsim lub temper thiab orientates tus qauv, thiab kev tswj kev laus laus precipitates lub zog ntxiv. Lub zeb muab sawb nyob rau hauv lub tiav lawm temper, thiab cov neeg siv yuav tsum tsis txhob cia siab tias yuav tsim cov khoom los ntawm lub khw kub kho; txoj hauv kev kom raug yog qhia qhov npau taws thiab tsim ib feem yam tsis tau rhuav tshem nws.
