Machinability txhais li cas rau Copper Alloys

1. Kev txhais ntawm "Machinability" rau tooj liab Alloys

Machineabilityntawm cov tooj liab alloys hais txog qhov yooj yim uas cov khoom tuaj yeem ua tau zoo li tus, txiav, los yog tsim siv cov txheej txheem machining (xws li, tig, drilling, milling, threading) thaum tuav qhov tseeb qhov tseeb, nto tiav, thiab lub neej cuab yeej. Nws yog ib qho tseem ceeb ntawm kev ua tau zoo metric rau cov ntawv thov kev lag luam, vim nws cuam tshuam ncaj qha rau kev tsim khoom, cov nqi tsim khoom, thiab cov khoom zoo.

Cov yam tseem ceeb uas cuam tshuam rau kev ua haujlwm ntawm tooj liab alloys suav nrog:

Hardness thiab Toughness: Nruab nrab hardness (tsis overly mos los yog brittle) sib npaug txiav kuj thiab nti tsim. Cov hlau nplaum ntau dhau (piv txwv li, tooj liab ntshiab) zoo li "cov pos hniav" cov cuab yeej, thaum cov hlau hnyav dhau ua kom cov cuab yeej hnav.

Chip Tsim: Zoo meej machinability yuav tsum tau cov khoom los tsim luv luv, nkig chips uas tawg yooj yim thaum lub sij hawm machining (es tsis txhob ntev, stringy chips uas cov cuab yeej los yog ua puas lub workpiece nto).

Lubricity: Copper alloys nrog ntuj lubricity (xws li, cov uas muaj cov hmoov txhuas los yog sulfur) txo kev sib txhuam ntawm cov cuab yeej thiab cov khoom ua haujlwm, txo cov cuab yeej hnav thiab txhim kho qhov chaw tiav.

Alloy Composition: Additives xws li txhuas (Pb), sulfur (S), los yog tellurium (Te) yog txhob txwm koom ua ke los txhim kho machinability los ntawm kev hloov kho cov khoom siv microstructure.

2. Copper Alloy Qib nrog zoo Turnability thiab Drillability

Cov qib tooj liab hauv qab no tau lees paub dav dav rau lawv cov kev ua haujlwm zoo tshaj plaws, ua rau lawv zoo tagnrho rau kev tig, drilling, thiab lwm yam kev ua haujlwm precision:

Hom alloy	Cov Qib Siab (UNS / ASTM)	Ntsiab Alloying Elements	Machinability Rating *	Qhov zoo rau Tig / Drilling	Tej kev siv
tooj dag	C36000 (Dawb-Txiav tooj dag)	Cu: ~ 61%; Zn: ~ 35%; Pb: ~ 3%	90–95%	- Luv luv, tawg tau chips uas tiv thaiv cov cuab yeej clogging. - Lubricity siab los ntawm txhuas, txo cov cuab yeej hnav. - Kev ruaj ntseg zoo heev thaum lub sij hawm machining.	Fasteners (screws, ceev, bolts), li qub, fittings, hluav taws xob Cheebtsam, precision machined qhov chaw.
	C37700 (High-Tsib tooj dag)	Cu: ~ 60%; Zn: ~ 37%; Pb: ~ 2-3%	85–90%	- Zoo ib yam li C36000 tab sis nrog cov ductility ntau dua, haum rau txoj kev tig / tho. - Zoo nto tiav tom qab machining.	Cov kav dej, lub zog, cov twj tso kua mis, cov khoom siv tsheb.
Bronze	C54400 (Phosphor Bronze, Dawb -Txiav)	Cu: ~ 85%; Sn: ~ 5%; Pb: ~ 5%	80–85%	- Cov hmoov txhuas ntxiv txhim kho nti tawg thiab txo cov quab yuam txiav. - Ua kom tawv tawv thaum muab kev ua haujlwm zoo.	Bearings, bushings, zog, hluav taws xob connectors, ntsuas qhov chaw.
	C64200 (Aluminium Bronze, Dawb-Txiav)	Cu: ~ 88%; Al: ~ 6%; Pb: ~ 4%	75–80%	- Sib npaug corrosion kuj (ib txwm ntawm txhuas bronze) nrog txhim kho machinability. - Haum rau drilling qhov tob thiab precision tig.	Marine hardware, industrial li qub, mechanical Cheebtsam xav tau ob qho tib si machinability thiab durability.
Copper{0}}Nickel Alloy (White Copper)	C75400 (Nickel Silver, Dawb -Txiav)	Cu: ~ 65%; Tsis muaj: ~ 18%; Zn: ~ 15%; Pb: ~ 2%	70–75%	- Lead txhim kho nti tsim, ua kom yooj yim tig thiab xyaum piv rau cov qauv tooj liab-nickel alloys. - Ua kom tiav qhov zoo thiab qhov raug qhov tseeb.	Kho kom zoo nkauj qhov chaw, suab paj nruag, hluav taws xob tiv tauj, precision fasteners.
Ntshiab tooj liab (Oxygen-Free)	C11000 (Oxygen-Free Copper, OFHC)	Cu: Ntau dua lossis sib npaug rau 99.99%	30–40%	- Nco tseg: Cov tooj liab ntshiab muaj cov khoom siv tsis zoo (mos, stringy chips, cuab yeej gumming). - Tsuas yog pom zoo rau kev ua haujlwm yooj yim nrog cov cuab yeej tshwj xeeb / roj av.	Hluav taws xob conductors, tshav kub exchangers (thaum machining yog tsawg).

*Machinability Rating: Tus txheeb ze rau C36000 dawb- txiav tooj dag (tseem 100% raws li qhov ntsuas rau kev ua haujlwm zoo). Cov feem pua siab dua qhia tau yooj yim dua machining.

Rau cov ntawv thov uas xav tau siab - ntim machining lossis precision Cheebtsam,C36000 dawb - txiav tooj dagyog tus nqi ntau tshaj - siv tau thiab siv dav xaiv. Rau corrosive ib puag ncig uas tooj dag tsis haum,C54400 dawb - txiav phosphor bronzelos yogC64200 dawb- txiav aluminium bronzemuaj qhov sib npaug ntawm machinability thiab durability.
