Cov lus qhia dav dav no tshawb txog ntau hom tooj dag, lawv cov khoom, thiab lawv cov kev siv dav dav, muab cov ncauj lus kom ntxaws txog cov khoom siv tsis tu ncua.

Hom thiab kev siv ntawm cov khoom siv tooj dag

Dab tsi yog tooj dag?

Brass yog ib qho alloy uas ua ke nrog tooj liab (Cu) thiab zinc (Zn) nyob rau hauv sib txawv proportions, nrog cov khoom ntxiv xws li txhuas, tin, aluminium, los yog manganese qee zaum ntxiv los hloov kho nws cov khoom. Nov yog qee cov yam ntxwv tseem ceeb:

• Kev sib xyaw: Feem ntau, niaj hnub tooj dag muaj txog 67% tooj thiab 33% zinc, tab sis qhov piv tau sib txawv.
• Xim: Nws txawv ntawm yellowish-kub mus rau reddish-kub los yog silvery-dawb, nyob ntawm qhov piv ntawm tooj liab-rau-zinc.
• Melting Point: Qhov kub ntawm 900 ° C txog 940 ° C, nyob ntawm qhov sib xyaw ntawm alloy.

Kev nplua nuj keeb kwm ntawm kev siv tooj dag

• Ancient keeb kwm: Brass yog thawj zaug siv ib ncig 5000 BCE hauv Mesopotamia los ntawm kev sib tsoo ntawm tooj liab thiab zinc ores.
• Nws yog Roman: Lub npe hu ua “Aes," tooj dag tau siv dav rau npib, cov mlom, thiab cov khoom zoo nkauj, qhia txog nws tus nqi hauv Roman faj tim teb chaws.
• Medieval Europe: Brass tau ua qhov tseem ceeb hauv kev cai dab qhuas artifacts, duab puab, thiab architectural ntsiab.
• Renaissance thiab Beyond: Siv rau cov artwork intricate, suab paj nruag, thiab nrog rau Industrial Revolution, tooj dag tau dhau los ua qhov tseem ceeb hauv kev siv tshuab thiab infrastructure.

2. Alpha-Beta Brass (Duplex tooj dag):

• Kev sib xyaw: Kwv yees li 55-65% tooj thiab 35-45% zinc, nrog rau lwm cov khoom xws li tin lossis txhuas.
• Cov khoom: Nyuaj thiab muaj zog dua alpha tooj dag, haum rau kev ua haujlwm kub, tsawg corrosion resistant.
• Daim ntawv thov: Cov kav dej fittings, iav, li qub, thiab kev siv dej hiav txwv.

Alpha-Beta Brass

3. Beta Brass:

• Kev sib xyaw: Ntau tshaj 45% zinc, ua kom muaj zog tab sis tsis tshua muaj ductile.
• Cov khoom: Siab zog, haum rau casting thiab kub ua hauj lwm, tsawg corrosion resistant.
• Daim ntawv thov: Cov khoom siv muaj zog zoo li cov ntsia hlau, txiv ntseej, bolts, thiab qhov chaw yuav tsum tau hnav tsis kam.

Lwm Yam Tseem Ceeb:

• Dawb Txiav Brass (Alloy C-360): Muaj cov hlau lead rau txhim kho machinability, siv nyob rau hauv precision qhov chaw xws li txiv ntseej, bolts, thiab fittings.
• Gilding Hlau (Liab tooj dag): Cov ntsiab lus tooj liab siab (95%), siv rau cov hniav nyiaj hniav kub, hniav trim, thiab artillery shells.
• High Tensile tooj dag: Xws li manganese kom muaj zog ntxiv, zoo tagnrho rau kev siv hnyav xws li marine cav thiab lub log hnyav.

Rooj 2: Cov cuab yeej thiab kev siv cov khoom siv tooj dag
