1. C79200 yog dab tsi?
UNS C79200 yog ib qho tooj liab leaded -nickel-zinc alloy - feem ntau hu ua leaded npib tsib xee nyiaj. Cov npib tsib xee muab cov hlau rau cov nyiaj -dawb tsos ntxiv rau kev txhim kho lub zog thiab corrosion kuj; cov ntsiab lus txhuas muab pub dawb -machining yam ntxwv. Nws yog machining -qib alloy, tsis yog high -hluav taws xob- cov khoom siv conductivity.
2. Kev sib xyaw ua ke (Hom, ib qho ASTM B151)
| Lub ntsiab | Cov ntsiab lus (%) |
|---|---|
| Cu | 59.0-66.5 |
| Ni | 9.0-11.0 |
| Pb | 1.0-2.0 |
| Zn | Tshuav |
3. Khoom
Nyiaj-dawb, tarnish{1}}cov tsos mob tsis zoo - "dawb tooj dag / npib tsib xee nyiaj" saib;
zoo zog thiab corrosion kuj nyob rau hauv atmospheric thiab me me tshuaj ib puag ncig;
machinability txog 80-90% ntawm C36000 dawb- txiav tooj dag - zoo heev rau cov ntsia hlau-tshuab ntau lawm;
hluav taws xob conductivity nruab nrab (kwv yees 6-10% IACS) - tsis yog rau kev siv fais fab;
raug tensile 480-620 MPa nyob rau hauv kos tempers, elongation 10-30% los ntawm temper.
4. Cov ntawv thov
Saib cov rooj plaub thiab cov hlua, cov hniav nyiaj hniav kub nrhiav pom, cov yuam sij thiab cov xauv, cov khoom siv tshwj xeeb, cov kav dej, cov khoom siv thiab cov koob yees duab, cov khoom siv kho kom zoo nkauj thiab cov fasteners uas yuav tsum muaj kev xeb dawb -cov tsos mob thiab kev ua haujlwm tau zoo.
5. Cov qauv thiab kev ua raws cai
ASTM B151 (qhib / bar), B122 (strip), B206 (hlau). C79200 muaj cov hmoov lead - txheeb xyuas RoHS, California Prop 65 thiab haus dej- txwv tsis pub dej rau lub khw muag khoom; lead-npib tsib xee nyiaj dawb (C76400/C77000) yog lwm txoj hauv kev uas yuav tsum tau ua.
