H59 vs H62: Sab-los ntawm-Sab piv
Qhov kev xaiv ntawm H59 thiab H62 feem ntau npau taws mus rau kev lag luam - tawm ntawm kev ua tau zoo / nqi thiab kev tiv thaiv corrosion / qhov zoo.
Kev sib xyaw thiab Microstructure (alpha vs beta)
Qhov sib txawv tseem ceeb nyob hauv microstructure:
H59:Qhov feem ntau ntawm cov nkig beta theem (alpha + beta) ua rau cov khoom nyuaj uas ib txwm ua luv luv, nkig chips thaum lub sij hawm machining.
H62:Feem ntau cov mos mos thiab ductile alpha theem ua kom zoo dua elongation thiab formability tab sis nyhav los tsim cov tawv tawv, ntev dua, thiab stringier chips.
Mechanical Properties
| Khoom | H59 tooj | H62 tooj | Kev cuam tshuam rau qhov kawg thiab kev ua tiav |
| Lub zog / Hardness | Siab dua me ntsis | Sib npaug / me ntsis qis | H59: Zoo dua rau cov qauv rigidity; H62: Zoo dua rau qhov txias txias. |
| Ductility (Elongation) | Lower (Brittle) | Tseem ceeb dua | H59: Tsawg txias ua haujlwm tau tso cai; H62: Haum rau riveting, flaring, lossis lub teeb khoov. |
Machineability
Piv txwv ntawm H59 Brass (cov chips luv, kev kub ceev) thiab H62 Brass (curled chips, zoo dua tiav) nti tsim hauv CNC machining.
Qhov no yog arguably qhov tseem ceeb tshaj plaws rau CNC khw:
H59 (Chip Formation):Ib txwm ua cov ntawv luv luv, me me, thiab brittle chips uas tawg yooj yim. Qhov no yog qhov zoo tshaj plaws rau kev ua haujlwm siab - ceev automated machining, xav tau cov nti tsawg heev - cov tswv yim tawg. Nws tso cai rau kev nrawm dua thiab pub tus nqi kom ua kom cov Khoom Siv Tshem Tawm (MRR).
H62 (Chip Formation):Nyias tsim ntev, curled, thiab stringier chips (tougher alpha theem). Kev tswj cov nti zoo yog qhov tseem ceeb, yuav tsum tau muab siab rau nti - rhuav tshem geometry lossis peck drilling cycles. Thaum muaj peev xwm qeeb qeeb, nws yooj yim dua kom ua tiav Ra qhov tseem ceeb thiab nruj dua qhov sib xws.
Deg tiav thiab Electroplating
Qhov zoo ntawm qhov chaw yog txuas ncaj qha mus rau microstructure:
H62:Cov qauv alpha theem zoo ib yam muab ntau duazoo ib yam, ruaj khov nto, ua rau kom zoo dua adhesion thiab ib tug ntau yam zoo li rau tom ntej electroplating (Nickel, Chrome).
H59:Kev ua tiav tiav yog ua tiav, tab sis ob -theem (alpha + beta) microstructure tuaj yeem ua rauinconsistent etchingThaum lub sij hawm ua ntej -plating tshuaj kho mob, yuav tsum tau nruj nreem npaj.
Dezincification & Dej tiv tauj
H62 feem ntau qhia qis qis rau dezincification dua H59 vim Cu thiab alpha ntau dua -theem dominance; Txawm li cas los xij, tsis yog H59 lossis H62 yog qib siab DZR. Rau kev sib cuag nrog dej (tshwj xeeb yog dej kub / mos / chlorinated), qhia DZR tooj dag (xws li EN tsev neeg CW602N / CuZn36Pb2As) lossis qhov sib npaug ntawm koj tus qauv. Paub meej cov kev cai (DZR, lead limits) hauv PO/spec.
