Cov khoom siv tooj dag yog dab tsi

1. Cov khoom siv tooj dag yog dab tsi?

Brass yog ibbinary los yog ntau- cov khoom sib txuasfeem ntau yog tsim los ntawmtooj liab (Cu)thiabZinc (Zn)- feem ntau siv tsis yog -ferrous alloy tsev neeg hauv kev lag luam hlau thoob ntiaj teb. Nws cov khoom yog tsim los ntawm kev kho cov tooj liab-zinc piv thiab ntxiv cov kab hlau rhuav tshem (xws li, tin, lead, npib tsib xee, aluminium), uas ua rau muaj ntau yam khoom siv nrog kev sib npaug ntawm kev ua haujlwm, kev tiv thaiv corrosion, lub zog, thiab tus nqi-effectiveness.

Cov yam ntxwv tseem ceeb & Kev lag luam cuam tshuam:

Composition Flexibility: Cov ntsiab lus tooj liab feem ntau yog li ntawm 55% mus rau 95% (zinc raws li qhov seem), nrog cov ntsiab lus tooj liab ntau dua txhim kho corrosion thiab ductility, thaum zinc cov ntsiab lus ntau dua txhim kho lub zog thiab hardness.

Core Properties:

Kev ua haujlwm zoo heev (tshwj xeeb tshaj yog cov qib tooj dag), ua rau nws zoo tagnrho rau kev ua haujlwm zoo ntawm cov khoom xws li li qub, fittings, thiab fasteners.

Zoo corrosion kuj rau atmospheric tej yam kev mob, dej tshiab, thiab uas tsis yog - oxidizing acids (ua los yog tin{1}} ntxiv qib muab kev tiv thaiv zoo rau dej hiav txwv los yog ib puag ncig hnyav).

Aesthetic golden-daj rau tooj dag- xim nto (patinates mus rau ib tug tsaus xim av lub sij hawm), haum rau architectural thiab zoo nkauj daim ntaub ntawv.

Tus nqi-zoo piv rau cov tooj liab dawb lossis tooj liab-nickel alloys, ua rau muaj kev xav tau siab hauv kev lag luam thiab cov neeg siv khoom lag luam.

Cov ntawv thov ib txwm (Kev lag luam- tsom):

Cov kav dej & HVAC: li qub, fittings, kav dej, thiab radiators.

Hardware & Fasteners: Screws, ceev, bolts, thiab hinges.

Automotive: Roj kab, connectors, thiab hniav trim.

Tubrog nkoj: Naval tooj dag fittings (tin{0}}ntxiv) rau cov dej ntsev.

Kho kom zoo nkauj & Architectural: Qhov rooj kov, railings, thiab signage.

2. Dab tsi yog cov khoom siv sib xyaw ntawm tooj dag?

Cov qib tooj dag yog cov qauv thoob ntiaj teb, nrog rau kev tsim raws li tshuaj lom neeg muaj pes tsawg leeg, cov khoom, thiab kev siv cov xwm txheej. Hauv qab no yog covcov qib kev lag luam dav davHauv kev lag luam hlau / hlau thoob ntiaj teb, nrog rau lawv cov qauv, kev sib xyaw, thiab kev siv tseem ceeb:

Qib Qib (ASTM)	Raws li International Standards	Core Chemical Composition (Qhov hnyav%)	Cov Khoom Tseem Ceeb & Cov Ntawv Thov Kev Lag Luam
C26000(Cartridge tooj dag)	ISO CuZn30; DIN CuZn30; JIS C2600	Cu: 68-71%, Zn: Tseem	High ductility, zoo heev formability; siv rau kos qhov chaw (xws li, raj, xov hlau, mos txwv casings). Ib qho ntawm cov khoom lag luam feem ntau yog qib tooj dag thoob ntiaj teb.
C36000(Free-Txiav tooj dag)	ISO CuZn36Pb2; DIN CuZn36Pb2; JIS C3604	Cu: 60-63%, Zn: Remainder, Pb: 2.0-3.0%	Superior machinability (ceev txiav, tsawg yam cuab yeej hnav); zoo tagnrho rau precision -cov khoom siv (valve, fittings, gears, fasteners). Kev lag luam loj nyob rau hauv industrial sectors.
C46400(Naval Brass)	ISO CuZn37Sn2; DIN CuZn37Sn2; JIS C4640	Cu: 60 ~ 63%, Zn: Remainder, Sn: 1.5-2.5%	Txhim kho seawater corrosion kuj thiab toughness; siv rau marine fittings, kiv cua shafts, thiab offshore hardware. Qhov tseem ceeb rau kev lag luam maritime.
C33000(Tsawg-Liab tooj dag)	ISO CuZn39Pb0.5; DIN CuZn39Pb0.5; JIS C3301	Cu: 57-60%, Zn: seem, Pb: ≤0.5%	Environmentally raws (cov ntsiab lus tsis tshua muaj hlau lead); ua tau raws li EU RoHS thiab US EPA cov qauv. Siv rau cov dej haus thiab khoom noj khoom haus -hu rau daim ntawv thov. Kev thov siab hauv kev lag luam tswj hwm.
C22000(Kev Lag Luam Bronze / Liab Brass)	ISO CuZn20; DIN CuZn20; JIS C2200	Cu: 78-82%, Zn: Remainder	High corrosion kuj thiab ductility; siv rau cov kav dej, cov kav dej, thiab cov khoom zoo nkauj. Kev lag luam dav dav hauv architectural thiab kav dej sectors.
