Copper chav kawm:
1.Brass - tshwj tsis yog tooj liab, zinc yog lub ntsiab additive. Cov qhab nia ntawm H96 txog H59. Feem ntau thiab zoo tshaj plaws yog H65, H62, thiab H59; Tus lej sawv cev rau feem pua ntawm tooj liab. Tus naj npawb loj dua, cov khoom siv softer thiab qhov ductility zoo dua. Thaum machining ntawm lub tshuab dhos thiab lub tshuab milling, feem ntau muaj qhov tshwm sim ntawm "nplaum riam".
2. Bronze - nco ntsoov beryllium bronze thiab phosphor bronze ua ntej
Lawv elastic heev! Lawv yog thawj xaiv rau springs thiab point-hu rau conductive Cheebtsam ... Tej zaum beryllium bronze yog zoo dua phosphor bronze; Lwm yam sawv daws yog tin bronze, txhuas bronze, thiab txhuas bronze. Tag nrho peb yog tsim nyog rau castings. Aluminium bronze muaj zog, hnav-tiv taus thiab ruaj khov. Corrosion yog qhov zoo tshaj plaws.
Hlau:
1. Stainless hlau - qhov no tsis piav ... txhua tus hauv ntiaj teb paub nws. Nyob rau hauv ib qho chaw, qhov siab dua cov ntsiab lus magnesium, qhov tsawg dua nws yuav xeb;
2. Hlau - nws yog hom nyias, ci dawb, zoo li borneol (lub plhaub tiv thaiv ntawm cov xov tooj pej xeem nyob rau hauv cov khw muag khoom noj uas muaj nyob rau hauv post-80s thaum yau), tom qab khoov, nws yog tsau. nrog rivets, uas yog yooj yim dua rau txheej txheem ceev, yog hais tias lub ntug tsis kho, nws yog ib qho yooj yim mus khawb cov neeg nrog ib tug ntse ntug.
3. Cold-rolled hlau - cov hlau uas peb feem ntau tham txog hauv peb lub neej niaj hnub, cov hlau uas siv ntau tshaj plaws hauv machining, yog tias koj kos "hlau" raws li cov khoom siv hauv cov duab kos, feem ntau yog lub neej ntawd, tsis muaj kev kho deg. xws li electroplating Nws yog ib qho yooj yim rau xeb; hauv qee qhov chaw uas tsis muaj qhov tshwj xeeb, nws yog qhov pheej yig dua los siv cov khoom siv no ntau dua tooj liab.
4. 4J36 - feem ntau hu ua invar lossis valve, cov khoom siv hlau nrog qhov ntsuas kub tsawg tshaj plaws uas tuaj yeem yuav hauv Suav teb yog nws!
Aluminium hom:
1. Duralumin (Ly12) - Lub hardness thiab mechanical zog kuj yog nruab nrab. Nws yog qhov tsim nyog tshaj plaws rau hauv qab phaj, vaj huam sib luag, txhawb kem ntawm cov cuab yeej thiab meters! Tab sis nco ntsoov tias nws tsis tuaj yeem khoov tau (nws yog nkig heev thiab yuav tawg thaum koj khoov nws).
2. Mos aluminium (Ly) - tsuas yog rov qab rau cov tawv tawv, nws muaj qhov tsis tshua muaj hardness thiab yooj yooj yim, thiab yog qhov haum tshaj plaws rau kev khoov!
