3. Kev tsim khoom & kev ua haujlwm yam ntxwv

C61300 (Naval tooj dag)

Kev ua thawj coj: Txias ua hauj lwm (kos duab, extrusion, stamping) vim siab ductility; kub ua hauj lwm rau tuab seem los yog complex forgings.

Casting: Txwv (qis fluidity tshaj tooj liab); tsuas yog siv rau cov duab yooj yim xwb.

Kev kho cua sov: Annealing (600-700 degree) rov qab ductility tom qab ua haujlwm txias; tsis muaj zog los ntawm kev kho cua sov (muaj zog los ntawm kev ua haujlwm txias).

Ua tiav: Polishes zoo rau ib tug golden luster; tej zaum yuav tsim ib tug nyias patina nyob rau hauv marine ib puag ncig (tiv thaiv, tsis corrosive).

C51900 (Phosphor Bronze)

Kev ua thawj coj: Txias ua hauj lwm (rau cov springs, xov hlau, thiab precision Cheebtsam) thiab kub ua hauj lwm (rau castings, forgings); peev casting yog feem ntau rau complex qhov chaw.

Kev kho cua sov: Annealing (550–650 degree) kom txo tau kev ntxhov siab; tuaj yeem ua nag lossis daus- tawv tawv hauv qee qhov sib txawv (xws li C52100) tab sis C51900 feem ntau ntxiv dag zog los ntawm kev ua haujlwm txias.

Tshuab dhos: Yuav tsum muaj cov cuab yeej carbide thiab txiav cov kua dej kom tsis txhob hnav cov cuab yeej; leaded phosphor bronze (xws li, C54400) yog qhov nyiam rau kev xav tau kev ua haujlwm siab.

Ua tiav: Txhim kho cov nplua nuj reddish-xim av patina dhau sijhawm (zoo nkauj thiab tiv thaiv); tuaj yeem plated (piv txwv li, npib tsib xee, chrome) rau kev txhim kho corrosion los yog zoo li.

4. Cov ntawv thov ib txwm

Cov ntsiab lus

Cov tub ntxhais sib txawv ntawm C61300 thiab C51900 nyob hauv lawv cov tshuab alloy: C61300 yog ib qhonaval tooj dag(Cu-Zn-Sn) optimized rau corrosion kuj (tshwj xeeb tshaj yog nyob rau hauv marine ib puag ncig) thiab formability, thaum C51900 yog ib tugphosphor tooj liab(Cu-Sn-P) tsim los rau lub zog siab, hnav tsis kam, thiab kev ua haujlwm qaug zog. C61300 yog qhov kev xaiv zoo tshaj rau tus nqi- siv tau zoo, corrosion- daim ntaub ntawv tiv taus uas yuav tsum tau ua haujlwm txias, thaum C51900 ua tau zoo tshaj plaws hauv cov khoom siv precision, springs, thiab hnav qhov chaw uas muaj zog thiab cov khoom siv kho tshuab tseem ceeb heev.
