Qhov sib txawv ntawm C18000 thiab C17510 tooj liab

C18000 thiab C17510 yog ob qho tib siTooj liab-npib tsib xee-silicon alloys(Feem ntau hu ua "silicon bronzes" lossis "nickel Silvers," tab sis lawv tsis muaj nyiaj), muaj nuj nqis rau lawv txoj kev sib xyaw ua ke, thiab corrosion tsis kam. Txawm li cas los xij, lawv txawv nyob rau hauv muaj pes tsawg leeg, cov khoom, thiab kev siv. Hauv qab no yog cov ncauj lus kom ntxaws:

1. Tshuaj lom neeg sib xyaw

Thawj qhov kev sib txawv ntawm lawv cov khoom sib txuas, uas ncaj qha rau lawv cov khoom:

Hlau	Qhov tseem ceeb (muaj ntau yam)
C18000	- Tooj (CU): ~ 95-97% - Nickel (NI): ~ 1.0-2.5% - silicon (si): ~ 0.5-1.5% - Cov ntsiab lus ntxiv: Cov nyiaj me me ntawm zinc (Zn), Tin (Sn), lossis Lead (PB) yuav nthuav tawm txhim kho machinance machince.
C17510	- Tooj (CU): ~ 96-98% - Nickel (NI): ~ 1.4-2.2% - silicon (si): ~ 0.4-0.8% - Chromium (CR): ~ 0.1-0.3% (tus tseem ceeb sib txawv, tsis tuaj kawm hauv C18000).

2. Cov Khoom Siv Neeg Kho Tshuab

Lawv cov kev sib xyaw ua rau sib txawv, hardness, thiab ductility, tshwj xeeb tshaj yog tom qab kev kho cua sov:

Lub zog tensile:

C18000: Feem ntau yog 620-760 MPa (ua kom sov).

C17510: Ntau dua, xws li ntawm 700-850 MPa (cov cua sov), vim muaj cov chromium ntxiv, uas txhim kho los nag.

Kev nyuaj:

C18000: ~ 180-220 HB (Brinell Hardness).

C17510: ~ 200-240 HB, nyuaj dua C18000, dua vim yog chromium qhov kev ua tau zoo.

Kev ua siab loj:

C18000: Ntau du Ntxiv (Elongation ~ 8-12% hauv Daim Ntawv Cua Sov).

C17510: Qw Me Me Qis (Elongation ~ 5-8%) vim muaj zog dua.

3. Kev kho kom sov

Ob alloys yog nagitation-hardenable, tab sis c17510 cov ntsiab lus chromium hloov kho nws tus cwj pwm kub:

C18000: Hatens los ntawm kev tsim cov nickel-silicon intermetallics thaum laus (feem ntau 400-450-450 degree).

C17510: Cov ntaub ntawv Chromium ntxiv (piv txwv li, CR-SI ZI sib txuas) thaum laus, ua rau muaj ntau dua ntawm cov khoom muaj peev xwm.

4. Corrosion Kuj

Ob alloys muaj cov zoo corrosion tsis kam nyob rau hauv ib puag ncig me me (xws li, huab cua, dej tshiab).

C17510, nrog chromium, nthuav qhia me ntsis zoo dua rau oxidation ntawm kev ntsuas kub thiab txhim kho cov tshuaj muaj piv rau C18000.

5. Kev thov

C18000: Siv rau hauv cov hluav taws xob txuas, hloov cov khoom siv, thiab cov fasteners uas muaj nyiaj tshuav qhov muaj zog, thiab lub tshuab yog xav tau. Nws txhim kho nws cov kev ua haujlwm sib haum xeeb.

C17510: Nyiam rau cov ntawv thov kev ntxhov siab ntau xws li springs, valve seem, uas muaj lub zog siab tshaj plaws thiab kev coj ua yog qhov tseem ceeb.

C17510 (nrog chromium) muaj lub zog siab dua thiab tawv dua C18000, ua nws haum rau kev thov kev siv tshuab ua kom zoo dua rau kev ua thiab dav dav-laj kam siv.
