Dab tsi yogC28000 tooj dag?
C28000 Muntz Hlau, feem ntau hu ua 60/40 tooj dag, yog tooj liab-zinc alloy nrog kwv yees li 60% tooj liab thiab 40% zinc. Nws ua ke lub zog siab nrog kev ua haujlwm zoo corrosion, ua rau nws tsim nyog rau ob qho tib si cov qauv thiab marine daim ntaub ntawv. C28000 yog tawv thiab muaj zog dua li cov tooj liab tooj liab (C26000) thiab yog siv dav hauv kev tsim khoom hauv nkoj, khoom vaj khoom tsev, thiab kev lag luam forgings.

FAQ
| Dab tsi yog sib npaug rau C28000 tooj dag? Lub alloy C28000 tooj dag yog ncaj qha thiab universally sib npaug rau Suav tus qauv alloy H62. Tshaj li qhov sib npaug ntawm qhov tseem ceeb no, nws sib raug rau ntau lwm cov npe loj thoob ntiaj teb: Hauv European (EN) tus qauv, nws yog hu ua CuZn37 lossis cov khoom siv code CW508L. Hauv Japanese (JIS) tus qauv, nws raug xaiv los ua C2800. |
| Dab tsi yog qhov sib xyaw ntawm tooj dag c28000? Brass UNS C28000 (sib npaug rau H62) feem ntau yog 60.0-63.0% Copper thiab 37.0-40.0% Zinc. Nws yog cov hlau lead uas tsis tshua muaj hlau lead (Pb) cov ntsiab lus ntawm 0.30% (feem ntau qis dua). Hlau yog txwv rau qhov siab tshaj plaws ntawm 0.07%, thiab tag nrho lwm yam impurities tsis pub tshaj 0.15%. Cov khoom sib xyaw no muab cov khoom muaj zog, tsim tau, thiab ntau yam kev siv dag zog. |
| Qhov txawv ntawm tooj dag 260 thiab 280 yog dab tsi? C260 daim hlau thiab cov nplooj ntawv yog cov ductile tshaj plaws ntawm cov tooj dag, thiab siv ntau dua li lwm cov tooj liab -zinc alloy. C280 (Muntz) tus yam ntxwv tseem ceeb tshaj plaws yog nws cov xim, thiab muaj zog dua, nyuaj thiab nruj dua li tooj dag ntawm cov ntsiab lus zinc tsawg dua. |
| Dab tsi yog qhov txawv ntawm C28000 thiab C26000 tooj dag? Qhov sib txawv tseem ceeb yog cov ntsiab lus tooj liab. C28000 tooj dag (60% Cu) muaj zog dua thiab zoo dua rau kev ua haujlwm kub, thaum C26000 tooj dag (70% Cu) yog cov khoom siv ntau dua, muaj qhov txias txias zoo dua, thiab siab dua corrosion kuj. |
| Lub melting point ntawm C28000 yog dab tsi? C28000 tooj dag muaj qhov sib txawv ntawm kwv yees li 900 txog 925 degrees Celsius (1650 txog 1700 degrees Fahrenheit). |
| C28000 tooj dag puas muaj txhuas? Yog, tab sis nyob rau hauv tsawg heev. ASTM specification tso cai rau siab tshaj plaws ntawm 0.30% txhuas, tab sis kev lag luam C28000 tooj dag feem ntau muab nrog cov ntsiab lus qis dua, feem ntau qis dua 0.07%, tsim nyog nws yog "qis- txhuas." |
| Dab tsi tempers yog C28000 tooj dag muaj nyob rau hauv? C28000 tooj dag sawb, ntawv, thiab phaj feem ntau muaj nyob rau hauv tempers xws li annealed (mos), quarter nyuaj (H01), ib nrab nyuaj (H02), nyuaj (H03), thiab caij nplooj ntoos hlav nyuaj (H04). |
| C28000 tooj dag piv rau C36000 tooj dag li cas? C36000 tooj dag yog lub siab - txhuas, dawb-machining alloy nrog cov nti zoo heev - tawg cov khoom (100% machinability). C28000 tooj dag muaj cov ntsiab lus txhuas qis dua, kev ua haujlwm tsis zoo (~ 40%), tab sis qhov ua tau zoo dua txias ua haujlwm thiab tsim tau. |
| Dab tsi cov qauv npog C28000 tooj dag sawb thiab ntawv? Tus qauv tseem ceeb rau C28000 tooj dag phaj, ntawv, thiab sawb hauv Asmeskas yog ASTM B36. Lwm cov qauv muaj xws li ASTM B370 rau phaj thiab ASTM B134 rau hlau. |
