A: Yog lawm.C12200 yog dav siv rau cov kav dej thiab cov kav dej. Nws muaj kev tiv thaiv corrosion zoo heev rau cov dej tsis qab thiab ua tau raws li cov qauv rau cov dej haus.
Q6: Qhov txawv ntawm C12200 thiab C1220T (JIS) yog dab tsi?
A: C1220T yog JIS sib npaug ntawm ASTM C12200.Cov tshuaj muaj pes tsawg leeg yog qhov tseem ceeb tib yam (Cu Ntau dua lossis sib npaug rau 99.9%, P 0.015-0.040%). Qhov sib txawv tseem ceeb yog nyob rau hauv temper designations thiab dimension tolerances. Rau feem ntau cov kev siv tshav kub exchanger, lawv yog interchangeable.
Q7: Lub melting point ntawm C12200 yog dab tsi?
A: Lub melting point yog1083℃(1981℃F). Ob leeg solidus thiab liquidus yog tib yam vim cov ntshiab tooj liab thiab tooj liab alloys muaj ib tug ntse melting ntau yam.
Q8: Dab tsi kev lag luam feem ntau siv C12200 raj?
