C44300 Copper Tubing yog dab tsi?

C44300 tooj liab tubing yog dab tsi?

C44300 tooj dag yog tooj dag formulated rau thawj tsim rau hauv cov khoom wrought. Cov khoom suav hais tias tsim nyog rau O61 (annealed) temper. CW706R yog EN tus lej tsim rau cov khoom siv no. C44300 yog UNS tus lej. Tsis tas li ntawd, EN chemical designation yog CuZn20Al2As. Lub npe British Standard (BS) yog CZ111. Thiab lub npe kev lag luam feem ntau yog 71.5-27.5-1.

Chemical Composition thiab Alloy Design

C44300 siv tooj liab (Cu) ua lub hauv paus (70.0% -73.0%), zinc (Zn) ua lub ntsiab alloying (sib npaug), thiab ntxiv 0.9% -1.2% tin (Sn) thiab 0.02% -0.10% arsenic (As). Qhov sib ntxiv ntawm tin ho txhim kho cov alloy qhov corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv inhibiting dezincification corrosion; Cov lej ntawm arsenic ntxiv txhim kho cov ciam teb ruaj khov thiab ua rau cov txheej txheem corrosion qeeb. Tsis tas li ntawd, cov ntsiab lus ntawm impurities xws li txhuas (Pb) thiab hlau (Fe) yog nruj me ntsis txwv (feem ntau Pb Tsawg dua los yog sib npaug rau 0.07%) kom ntseeg tau cov khoom purity.

Lub cev muaj zog

Ceev: Kwv yees li 8.53 g / cm³, me ntsis siab dua li cov tooj dag zoo tib yam, tab sis tseem sib zog dua li corrosion feem ntau - cov hlau resistant.

Hluav taws xob / Thermal Conductivity: Hluav taws xob conductivity yog 28% IACS, thiab thermal conductivity yog kwv yees li 10⁹ W / (m·K), haum rau daim ntaub ntawv uas yuav tsum tau ob qho tib si hluav taws xob conductivity thiab kub dissipation.

Corrosion Resistance: Zoo heev corrosion kuj nyob rau hauv seawater, dej tshiab, thiab chlorine -muaj xov xwm; tseem ceeb tiv thaiv dezincification (dhau ASTM B858 dezincification test); ntev -lub sij hawm kev pab kub txwv yog kwv yees li 200℃.

Mechanical Properties

Tensile Strength: Kwv yees li 330-380 MPa hauv lub xeev annealed, ncav cuag 500-600 MPa tom qab ua haujlwm txias.

Elongation: Ntau dua lossis sib npaug li 40% elongation hauv lub xeev annealed, tuav 15% -25% hauv lub xeev txias-dov, nthuav tawm cov yas siab.

Hardness: Hom hardness yog HB 60-100, kho tau los ntawm kev ua haujlwm txias.

Cov khoom siv

Marine Engineering: Nkoj condenser raj, desalination pipelines, subsea li qub.

Zog & Lub Zog: Thermal power plant condensers, nuclear cooling systems, refinery heat exchangers.

HVAC: AC refrigerant tubes, chlorinated dej kub kav.

Mechanical Parts: Sib sib zog nqus-draw pins/caij nplooj ntoos hlav, corrosion{1}}resistant bearing bushings.
