C23000 liab tooj daj (85% cu -15}}}}% Zn) tau dhau los ua cov khoom kho kom zoo nkauj, suab paj nruas tsim thiab ua suab paj nruag engineering. Hauv daim ntawv no, peb yuav txheeb xyuas nws cov cwj pwm muaj pes tsawg leeg, cov txheej txheem tshiab thiab cov ntawv thov tshiab.
I. Cov yam ntxwv tseem ceeb ntawm C23000 Cov Khoom Siv
Kev sib xyaw (Astm B36 Txuj Ci):
Copper (Cu): 84.0%-86.0% (to lay the foundation for corrosion resistance)
Zinc (ZN): 14. {0% {2}}}}}}}}}}} (tswj cov xim thiab tawv tawv)
Kws kho mob tswj: hlau (FE)<0.05% (to protect the cold workability)
Kev Ua Tau Zoo:
Aesthetics & durability:
Rose kub xim (ntau dua liab dua c21000), ib txwm tsim dense oxide zaj duab xis los tawm tsam kev sib deev;
Dej hiav txwv Corrosion<0.02 mm/year, superior to 304 stainless steel (0.1 mm/year).
Acoustic thiab kev vibration kev ua tau:
Acoustic impedance (4.7 × 10 teev pa-s \/ m) kom phim cov kev xav tau ntawm cov twj paj nruag;
Damping coefficient yog 30% siab dua li ntshiab tooj liab, haum rau kev co damping Cheebtsam.
Ua kev hloov kho tau:
Ntau yam ntawm kub ua qhov kub (650-800 degree), haum rau cov forging thiab molding;
Txias rolling deformation tus nqi txog li 60%, tsis muaj annealing kom ua kom precision brrows.
Thib ob, Daim Ntawv Thov Niaj Hnub nimno
Architecture thiab Art
Lub Tsev Txawj Ua Zoo Tshaj Tawm: Lub Koom Txoos dome Hniav Zoo Nkauj Lub Tsev, Xws Li Lub Tsev Paris Opera Lub Tsev);
Cov ntaub ntawv duab puab: 3D luam tawm cov duab puab hlau, interlayer sib txuas lus lub zog ntau dua los yog sib npaug rau 300 MPa.
Cov Suab Paj Nruag Raug
Cua Instrument Tubes: Trumpet, Saxophone Lub Cev, 15% nce rau hauv cov suab sov tshaj C26000 (70\/30 tooj dag);
Percussion cymbals: kub-kho hardness hrb 65-75}}, ntsuas ductility thiab crisp suab zoo.
Tubrog voos & Tshuaj
Desalination cog condenser Tube, chlorine ion corrosion resistance lub neej ntau dua 20 xyoo;
Chemical plant explosion-proof tools, collision without spark (ignition energy>100MJ).
Cov Khoom Siv High-ag
Spacecraft waveGroor raj, teeb liab kis puas<0.5dB/m (Ka band);
Kev kho tshuab ua pa valve dogphragm, biocompatibility tau lees paub los ntawm ISO 10993.
Thib peb, Qhov Txheej Txheem Kev Yooj Yim
Kev Kho Cua Sov Optimization:
Annealing: 450-550 degree × 1h → dej quenching, grain loj lov {2}} qib;
Kev ntxhov siab kev hloov siab: 250 degree × 2H, khaws cia 90% lub zog txias.
Nto Kho:
Tshuaj lom neeg muaj yeeb yaj kiab (selenate daws) kom ua tiav cov puav pheej xeb;
Electropretic Xim (EPD) huab cua txog li quav 2000 teev.
Precision Casting: Silicone Sol Precison Rofting, nto rougness ra tsawg dua los yog sib npaug rau 1.6μm.
Cov ntsiab lus kev lag luam:
Zinc Ntuj solessive corrosion (Dezincification) nyiam, xav tau ntxiv 0. 1% arsenic (raws li) inhibition.
