6061 nyob rau hauv T6 temper yog qhov dav tshaj plaws uas tau teev tseg dav dav - lub hom phiaj ntawm txhuas alloy nyob hauv lub ntiaj teb. Nws muab cov qib siab zog ze rau cov hlau me me ntawm ib feem peb ntawm qhov hnyav nrog kev txhim khu kev qha, zoo corrosion kuj thiab kev kho cua sov, uas yog vim li cas nws tshwm nyob rau hauv aerospace fittings, automotive lug, semiconductor tooling, tsheb kauj vab thav ntawv thiab countless machined Cheebtsam. To taub qhov T6 npau taws tiag tiag ua li cas, thiab qhov twg nws cov kev txwv dag, yog qhov tseem ceeb rau kev siv cov hlau zoo.
Tshuaj muaj pes tsawg leeg ntawm 6061
6061 belongs rau 6xxx series, nyob rau hauv uas magnesium thiab silicon yog lub ntsiab alloying ntsiab. Lawv qhov sib npaug yog sib npaug kom lawv sib xyaw ua ke rau hauv magnesium silicide thaum lub sij hawm kho cua sov, thiab cov precipitates zoo uas daim ntawv yog lub luag hauj lwm rau cov alloy lub zog.

Qhov T6 Temper Ua li cas
Lub npe T6 piav qhia txog peb - theem kev kho cua sov uas siv cov hlau rau nws lub zog ua haujlwm siab tshaj plaws.
Kev kho cua sov:cov khoom yog tuav ntawm li 530 degrees C kom cov alloying ntsiab dissolve tag nrho rau hauv ib zaug xwb -theem solid solution.
Quenching:ceev cua txias ntxiab cov ntsiab lus nyob rau hauv lub xeev supersaturated thiab suppresses nag ntxov ntxov.
Artificial aging:tswj reheating rau kwv yees li 175 degrees C precipitates zoo heev, sib npaug faib Mg2Si hais uas cuam tshuam kev txav mus los.
Cov kab ke no yog dab tsi cais 6061 T6 los ntawm cov mos O thiab T4. Nws kuj piav qhia txog qhov kev txwv ntawm kev tsim cov hlau tseem ceeb: txhua qhov txuas tom ntej los yog siab - qhov kub thiab txias raug overages tus qauv precipitate thiab softens cov khoom nyob rau hauv thiab ib ncig ntawm thaj tsam cuam tshuam.

Lub zog -rau- qhov hnyav piv yog qhov zoo ntawm cov xov xwm: 6061 T6 ib feem yog nqa cov khoom thauj uas yuav xav tau cov hlau seem hnyav dua peb zaug, thiab nws cov thermal conductivity ua rau nws siv tau rau cov dab dej kub, cov phaj txias thiab cov khoom siv hluav taws xob, thaum txog 40% IACS ua tau raws li cov kev xav tau ntawm cov tsheb npav thiab cov roj teeb enclosures.
Machining, sib sau thiab Vuam
Machining:dawb-machining tus cwj pwm, kwv yees li 60% ntawm cov dawb- txiav tooj dag, txhawb nqa kev tshem tawm siab, nruj kam rau ua thiab huv si saum npoo tiav ntawm CNC tshuab dhos thiab machining chaw.
Kev tsim:T6 temper txwv ductility, yog li nruj khoov thiab sib sib zog nqus draws yog ua nyob rau hauv lub T4 mob thiab ib feem yog ces hnub nyoog rau T6.
Vuam:Gas hlau arc thiab roj tungsten arc vuam yog cov tswv yim nrog 4043 muab tub lim rau tawg tsis kam lossis 5356 muab tub lim rau kev sib koom ua ke ntau dua; lub tshav kub- thaj tsam cuam tshuam poob lub zog thiab tag nrho rov qab yuav tsum tau tshaj tawm -weld cua sov kho, uas feem ntau tsis ua haujlwm ntawm cov rooj sib txoos loj.
Corrosion thiab finishing:lub alloy tiv taus atmospheric, dej tshiab thiab ntau qhov chaw muaj, thiab nws anodizes thiab hmoov coats huv si. Tooj liab nyob rau hauv cov muaj pes tsawg leeg me ntsis txo cov kev tiv thaiv rau aggressive chloride kev pab cuam piv nrog 5xxx los yog 6xxx alloys uas tsis muaj tooj liab.
Qhov twg 6061 T6 Phaj thiab Bar Siv
Cov ntawv thov muaj xws li dav hlau thiab drone cov qauv fittings, automotive brackets thiab chassis Cheebtsam, tsheb thiab trailer lub cev, hydraulic manifolds, pneumatic thooj voos kheej kheej, semiconductor thiab automation fixture daim hlau, precision jigs, marine hardware saum toj no waterline, structural seem rau towers thiab cov khoom muaj zog, thiab cov neeg siv khoom xav tau cov khoom siv. Phaj feem ntau muab los ntawm 3 hli mus rau 200 hli tuab, nrog extruded bar, raj thiab profile muaj nyob rau hauv tus qauv thiab kev cai tuag.
Cov khoom lag luam feem ntau raug txiav txim tawm tsam thoob ntiaj teb phaj, bar lossis extrusion specification, thiab cov neeg yuav khoom yuav tsum hais qhov npau taws T6 lossis T651 kom meej meej, ua ke nrog qhov ntev ntev, flatness thiab ib qho ultrasonic lossis conductivity yuav tsum tau txais.
