Taw qhia
Kab lus no piav qhia txog qib ASTM sib npaug ntawm H62 tooj dag sawb. Suav tooj dag qib xws li H96, H90, H68, H65, H62 thiab H59 yog txhais hauv GB / T 5231 los ntawm lawv cov ntsiab lus tooj liab thiab yog cov qauv siv hauv Suav teb kev lag luam tooj liab. Tus lej tom qab H muab tus lej tooj liab nominal, yog li H62 muaj txog 62 feem pua tooj liab thiab H96 txog 96 feem pua.
Qib System
Nyob rau hauv Suav system, H96 thiab H90 yog siab- tooj liab tooj dag nrog zoo formability thiab conductivity, H68 thiab H65 yog ib leeg-theem brasses nrog qhov zoo tshaj plaws txias-txoj kev coj cwj pwm, H62 yog qhov dav -lub hom phiaj qib ntsuas lub zog, tus nqi thiab formability, thiab H510 yog ob lub ntsiab lus qis tshaj plaws thiab lub zog siab tshaj plaws ntawm tus nqi qis. Tib yam khoom raug xaiv los ntawm UNS tus lej hauv ASTM kev xyaum, nrog H96 sib raug rau C21000 thiab H62 sib piv rau C27400.
Khoom los ntawm Qib
Cov ntsiab lus tooj liab siab dua muab cov ductility zoo dua, tiv thaiv corrosion thiab conductivity, thaum zinc ntau dua muab lub zog ntau dua thiab qis dua. Rau kev kos duab sib sib zog nqus, H68 thiab H65 yog qhov nyiam vim tias lawv zoo heev elongation; rau cov khoom siv dav dav, fasteners thiab fittings, H62 muaj qhov sib npaug zoo tshaj plaws; rau kev ua haujlwm kub thiab kev lag luam, H59 yog siv.
| Qib | Cu% | Cim | Hom kev siv |
|---|---|---|---|
| H96 | 95 - 97 | Siab ductility | Radiator raj, cov khoom zoo |
| H68 | 67 - 70 | Qhov zoo tshaj plaws sib sib zog nqus kos duab | Plhaub, kho vajtse |
| H65 | 63.5 - 66.5 | Zoo formability | Fasteners, terminals |
| H62 | 60.5 - 63.5 | Lub hom phiaj dav dav | Fittings, hlau, tube |
| H59 | 57 - 60 | Ob-theem, muaj zog | Kub-cov haujlwm ua haujlwm |
Daim ntawv thov
Suav tooj dag qib yog siv rau cov raj radiator, fasteners, terminals, hardware, sib sib zog nqus- rub shells, instruments, condenser raj thiab cov khoom zoo nkauj. Txhua qib yog muab raws li daim ntawv, sawb, pas nrig, hlau thiab raj raws li cov khoom txheem xws li GB / T 2040 rau daim ntawv thiab sawb, GB / T 1527 rau kos raj thiab GB / T 4423 rau pas nrig.
Kev xaiv thiab pov thawj
Paub meej cov ntsiab lus tooj liab tiv thaiv GB / T 5231 thiab daim ntawv khoom tawm tsam cov qauv khoom lag luam. Tshawb xyuas cov khoom siv kho tshuab thiab tshuaj ntsuam xyuas ntawm daim ntawv pov thawj, thiab sib tw qib rau kev tsim thiab kev txhim kho corrosion ntawm ib feem.
