Raws li qhov tseem ceeb ntawm cov khoom siv hluav taws xob thiab cov teeb liab kis tau tus mob, kev ua tau zoo ntawm cov khoom sib txuas feem ntau nyob ntawm lub cev, tshuaj, thiab cov khoom siv ntawm cov khoom siv. Cov xwm txheej sib txawv muaj cov kev xav tau sib txawv rau cov khoom siv conductivity, corrosion resistance, mechanical zog, thiab kev ua haujlwm. Yog li ntawd, kev xaiv cov ntaub ntawv tshawb fawb yog qhov tseem ceeb thaum tsim thiab tsim khoom kom ntseeg tau tias muaj kev ntseeg siab thiab kav ntev ntawm kev sib txuas.
Cov khoom siv hlau yog lub hauv paus ntawm kev sib txuas conductivity thiab elastic load bearing. Copper thiab nws cov alloys tau siv dav vim lawv cov conductivity siab thiab zoo ductility. Brass, tshwj xeeb, sib txuas lub zog nrog kev yooj yim ntawm kev ua thiab feem ntau yog siv rau cov pins, qhov (socket), thiab lwm yam khoom siv. Phosphor bronze exhibits zoo heev elasticity thiab qaug zog kev ua tau zoo, ua rau nws tsim nyog rau kev sib cuag tsim yuav tsum tau rov hais dua thiab tshem tawm. Beryllium tooj liab sib xyaw ua ke muaj zog thiab zoo conductivity, ua rau nws muaj txiaj ntsig zoo hauv qhov chaw- txwv tsis pub siv yuav tsum muaj kev sib cuag siab. Stainless hlau feem ntau yog siv rau vaj tse los yog xauv mechanisms, thiab nws zoo heev corrosion kuj thiab txhua yam muaj zog cia nws tiv taus qhov hnyav ib puag ncig. Yuav kom ua tau raws li qhov yuav tsum tau muaj kev ntseeg siab, qee qhov kev sib txuas siab - kawg siv cov hlau zoo nkauj plating, xws li kub, nyiaj, los yog palladium-nickel alloys, kom txo tau kev sib cuag, inhibit oxidation, thiab txhim kho teeb liab kev ncaj ncees thiab lifespan.
Cov ntaub ntawv rwb thaiv tsev txiav txim siab theem ntawm kev sib cais hluav taws xob thiab kev txhawb nqa txhua yam. Engineering plastics yog qhov kev xaiv tseem ceeb. Polyamide (nylon) muaj zoo toughness thiab hnav tsis kam thiab yog yooj yim molded rau hauv complex qauv; polycarbonate muaj cov pob tshab zoo thiab muaj zog tiv thaiv, ua rau nws tsim nyog rau cov khoom siv nrog saib qhov rais lossis qhov chaw sab hauv yuav tsum tau saib xyuas; PBT muaj kev tiv thaiv kub zoo thiab qhov ruaj khov thiab feem ntau siv nyob rau hauv siab - qhov kub thiab txias. Cov ntaub ntawv hloov kho, los ntawm kev ntxiv cov iav fiber ntau lossis nplaim hluav taws kub, tuaj yeem txhim kho lub zog, tiv thaiv tshav kub, thiab hluav taws kub, ua tau raws li cov qauv kev nyab xeeb hauv kev lag luam xws li kev lag luam, kev thauj mus los, thiab aerospace.
Cov ntaub ntawv sib xyaw thiab cov thev naus laus zis kho saum npoo nthuav dav daim ntawv thov ciam teb ntawm cov ntaub ntawv. Anodizing aluminium plhaub muab hnav tsis kam thiab corrosion kuj thaum tuav lub teeb; zinc alloys muaj kev tuag zoo-casting formability, haum rau kev tsim complex- zoo li lub plhaub, thiab electroplating txhim kho huab cua tiv thaiv. Ntxiv nrog rau cov hlau muaj txiaj ntsig, tin thiab npib tsib xee kuj yog cov kev xaiv rau saum npoo plating ntawm kev sib cuag kom ua tiav qhov sib npaug ntawm tus nqi thiab kev ua haujlwm.
Feem ntau, kev xaiv cov khoom siv txuas yuav tsum tau xav txog cov kev xav tau ntawm kev coj ua, ib puag ncig, kev ua neej nyob, thiab tus nqi -kev ua tau zoo. Cov khoom siv hlau ua kom tsis muaj - ua haujlwm siab thiab siab - kev sib kis tau zoo, cov ntaub ntawv insulating tau lees tias muaj kev nyab xeeb kev sib cais thiab kev ruaj ntseg, thaum kev kho saum npoo txuas ntxiv kev pab cuam lub neej thiab nthuav dav daim ntawv thov. Kev nkag siab tob txog cov yam ntxwv thiab cov xwm txheej tsim nyog ntawm ntau yam ntaub ntawv pab kom tsis txhob muaj kev pheej hmoo thaum lub sij hawm tsim qauv thiab txhim kho kev ua tau zoo ntawm kev sib txuas hauv nruab nrab ntawm kev ua haujlwm sib txawv.
