Tam sim no, kev lag luam muaj ntau yam khoom siv fastener, feem ntau suav nrog carbon steel, stainless hlau, hlau alloy, tooj liab thiab tooj liab alloys, aluminium alloys, thiab plastics. Hauv qab no yog cov lus qhia ntxaws ntxaws rau ntau yam khoom siv fastener:
Carbon Steel: Cov pa roj carbon steel yog ib qho ntawm cov khoom siv feem ntau siv rau cov fasteners, muaj cov cuab yeej zoo thiab ua haujlwm tau zoo. Raws li cov ntsiab lus carbon, carbon steel tuaj yeem muab faib ua qis- carbon steel, nruab nrab- carbon steel, thiab siab - carbon steel. Tsawg- cov pa roj carbon steel fasteners muaj lub zog qis dua tab sis zoo dua plasticity thiab toughness, ua rau lawv yooj yim rau txheej txheem thiab vuam, thiab feem ntau siv rau hauv cov ntawv thov uas tsis tas yuav muaj lub zog siab. Nruab nrab-carbon thiab siab- cov pa roj carbon steel fasteners muaj zog dua thiab hardness, haum rau daim ntaub ntawv uas hnyav loads.
Stainless hlau: Stainless hlau fasteners muaj zoo heev corrosion kuj thiab siv tau rau ncua sij hawm nyob rau hauv hnyav ib puag ncig yam tsis muaj xeb. Stainless hlau cov ntaub ntawv feem ntau suav nrog austenitic stainless hlau, martensitic stainless hlau, thiab ferritic stainless hlau.
Alloy Steel: Alloy steel fasteners yog tsim los ntawm kev ntxiv ib lossis ntau lub ntsiab lus alloying (xws li chromium, nickel, molybdenum, thiab lwm yam) rau carbon steel, uas ua rau muaj zog dua, hardness, thiab corrosion kuj. Alloy steel fasteners yog tsim rau cov ntaub ntawv uas muaj cov loads siab, siab kub, los yog corrosive media, xws li nyob rau hauv aerospace thiab petrochemical industries.
Copper thiab Copper Alloys: Tooj thiab tooj liab alloy fasteners muaj hluav taws xob zoo, thermal conductivity, thiab corrosion kuj, thiab feem ntau siv hauv hluav taws xob, hluav taws xob, thiab tshuaj lom neeg kev lag luam. tooj dag fasteners, tshwj xeeb, yog dav siv vim lawv zoo machinability thiab corrosion kuj.
Aluminum Alloys: Aluminum alloy fasteners have the advantages of low density, high strength, and good corrosion resistance, making them suitable for applications with strict weight requirements, such as in aerospace and automotive manufacturing.
Plastics: Yas fasteners yog lub teeb yuag, muaj kev tiv thaiv zoo, thiab muaj zog corrosion kuj, thiab feem ntau yog siv rau hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov khoom ua si.
