Nws yuav tsum yog high-carbon steel, aluminium tsis zoo li carbon steel! Uas tau hais tias, qhov sib txawv ntawm ob cov ntaub ntawv feem ntau yog qhov hnyav, thiab cov thav duab ua los ntawm txhuas yog hnyav dua thaum piv nrog tib lub zog txhua yam. Los yog raws li lwm qhov kev xav, xws li qhov hnyav ntawm tus ncej yog hais txog tib yam, lub zog txhua yam ntawm aluminium ncej yuav tsis muaj zog. Tab sis yog tias tsuas yog rau kev thauj mus los dav dav, aluminium tau zoo heev.
Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm high-carbon steel thiab aluminium alloy?
High-carbon steel, feem ntau hu ua cov cuab yeej hlau, muaj cov ntsiab lus carbon xws li 0.60 feem pua rau 1.70 feem pua thiab tuaj yeem ua kom tawv thiab tempered. Hammers, crowbars, thiab lwm yam yog ua los ntawm steel nrog 0.75 feem pua cov ntsiab lus carbon; tej cuab yeej xws li xyaum xyaum, kais, reamers, thiab lwm yam yog ua los ntawm steel nrog 0.90 feem pua carbon ntsiab lus. rau 1. 00 feem pua ? hlau. Kev kho cua sov tuaj yeem tau txais tom qab siab? s hardness (HRC60 a 65) thiab zoo hnav tsis kam. Nyob rau hauv lub annealed mob, lub hardness yog nruab nrab thiab lub machinability yog zoo. Aluminium alloy yog ib qho ntawm cov khoom siv uas tsis yog-ferrous hlau ntau tshaj plaws hauv kev lag luam thiab tau siv ntau hauv aviation, aerospace, tsheb, machinery manufacturing, shipping, thiab tshuaj industries. Txoj kev loj hlob sai ntawm kev lag luam kev lag luam thiab kev xav tau ntau ntxiv rau welded structural qhov chaw ntawm aluminium alloy tau coj mus rau qhov kev tshawb fawb tob txog kev weldability ntawm aluminium alloy.
Tam sim no, aluminium alloy yog feem ntau siv alloy. Zoo thermal conductivity: Cov thermal conductivity ntawm txhuas yog siab heev, thib ob tsuas yog nyiaj, kub, thiab tooj liab ntawm cov hlau, thiab peb npaug ntawm cov hlau.
