Dab tsi yog Zinc -Aluminium Phaj? Properties, Siv & Muaj nuj nqis

Zinc- txhuas daim hlau, tseem hu ua Zn-Al alloy daim hlau, yog hybrid hlau los xij crafted los ntawm kev sib xyaw zinc nrog txhuas-ob hlau uas sib ntxiv rau ib leeg kom xa cov kev ua tau zoo tshaj cov zinc lossis txhuas ib leeg. Muaj nyob rau hauv ntau qhov sib piv ntawm alloy (feem ntau 5% mus rau 50% txhuas cov ntsiab lus), cov phaj no yog tsim los ua ke zinc qhov tshwj xeeb corrosion kuj nrog txhuas lub teeb yuag zog thiab formability. Tsis zoo li ib qho - hlau phaj, zinc- txhuas alloys muaj qhov sib npaug ntawm cov khoom, ua rau lawv mus- xaiv rau qhov chaw hnyav thiab siab - hnav daim ntaub ntawv. Ua raws li cov qauv thoob ntiaj teb xws li ASTM B690, EN 988, thiab GB / T 1175, lawv tau txais kev pom zoo thoob plaws hauv hiav txwv, kev tsim kho, tsheb, thiab kev lag luam thoob ntiaj teb.

Kev ua tau zoo ntawm zinc- txhuas daim hlau hinges ntawm lawv cov alloy muaj pes tsawg leeg- kev hloov me me hauv cov ntsiab lus aluminium drastic hloov lawv cov yam ntxwv. Tsawg- aluminium alloys (5-10% Al) khaws cov zinc cov khoom zoo thaum txhawb kev tiv thaiv corrosion, zoo tagnrho rau cov hniav thiab tiv thaiv txheej. Nruab nrab-aluminium variants (15-30% Al) cuam tshuam qhov sib npaug ntawm lub zog thiab ductility, haum rau cov khoom siv. High{13}}Aluminium alloys (35-50% Al) yog qhov tseem ceeb ntawm lub zog hnyav thiab hnav tsis kam, sib tw nrog cov hlau tsis muaj steel hauv kev thov. Qhov no versatility, ua ke nrog zoo heev weldability thiab nto kho, ua rau zinc-aluminium daim hlau hloov tau yooj yim rau tej yaam num uas durability thiab nqi-zoo yog tsis-negotiable.

Core Properties of Zinc-Aluminium Phaj

Zinc-Aluminium daim hlau sawv tawm rau lawv qhov sib xyaw ua ke ntawm zinc thiab txhuas qhov zoo tshaj plaws, txhim kho los ntawm kev sib koom ua ke ntawm alloy:

1. Exceptional Corrosion Resistance

Lub ntsiab kom zoo dua ntawm zinc- txhuas daim hlau yog lawv cov kev tiv thaiv corrosion zoo tshaj - ua haujlwm zoo dua cov zinc thiab txhuas hauv ntau qhov chaw. The alloy forms a dense, adherent oxide layer that acts as a barrier against moisture, saltwater, chemicals, and atmospheric wear. Piv txwv li, Zn-5Al daim hlau muaj txog li 3x zoo corrosion kuj dua li cov zinc ntshiab nyob rau hauv ntug dej hiav txwv thiab chaw lag luam, thaum Zn-22Al alloys ua tau zoo nyob rau hauv acidic thiab alkaline ib puag ncig. Qhov kev tiv thaiv no tshem tawm qhov kev xav tau ntawm cov txheej txheem ntau zaus lossis kev saib xyuas, txuas ntxiv kev ua neej nyob rau sab nraum zoov, dej hiav txwv, thiab kev siv tshuaj lom neeg.

2. Lub zog sib npaug & Lub teeb yuag tsim

Zinc- cov phaj txhuas yog sib zog dua li cov zinc ntshiab (qhov ceev 5.0-6.0 g/cm³ vs. zinc's 7.14 g/cm³) thaum muab lub zog tensile ntau dua li ob niam txiv hlau. Nruab nrab{11}}aluminium alloys (piv txwv li, Zn-15Al) muab lub zog tensile ntawm 200-250 MPa, ua rau lawv haum rau cov khoom siv yam tsis muaj qhov hnyav ntxiv. High-aluminium variants (Zn-40Al) ntxiv zog rau 300+ MPa, rivaling me ntsis steel tab sis tshuav 30% sib dua. Qhov kev sib npaug no ua rau lawv zoo tagnrho rau cov khoom siv hnyav xws li cov khoom siv tsheb thiab cov qauv hauv hiav txwv, qhov twg lub zog thiab kev txav mus los yog qhov tseem ceeb.

3. Zoo heev Formability & Machinability

Tsis zoo li nkig corrosion-cov hlau tsis muaj zog, zinc- cov phaj aluminium khaws cov khoom zoo, txawm nyob hauv nruab nrab - lub zog alloys. Tsawg-rau- nruab nrab aluminium variants (Zn-5Al rau Zn-22Al) tuaj yeem khoov, dov, stamped, thiab sib sib zog nqus- kos rau hauv cov duab nyuaj yam tsis muaj qhov tawg-zoo meej rau cov khoom siv xws li cov khoom siv dai kom zoo nkauj thiab lub tank liners. Lawv kuj yooj yim rau tshuab nrog cov cuab yeej txheem, txhawb kev txiav, drilling, thiab threading. Qhov formability no txo ​​cov pov tseg thaum lub sij hawm fabrication thiab enables high-volume ntau lawm, ib tug tseem ceeb txiaj ntsim rau manufacturers.

4. Muaj zog Weldability & Kev Koom Tes Muaj Peev Xwm

Zinc -Aluminium daim hlau compatibility nrog welding txoj kev (TIG, MIG, kuj welding) yooj yim los ua ke thiab fabrication. Tsis zoo li cov zinc ntshiab, uas tuaj yeem raug kev txom nyem los ntawm brittle welds, cov ntsiab lus ntawm txhuas nyob rau hauv cov alloys txhim kho weld ductility thiab lub zog. Kom tau txais txiaj ntsig zoo tshaj plaws, sib piv Zn-Al muab tub lim hlau yog siv los tswj kev tiv thaiv corrosion thiab cov khoom siv kho tshuab tom qab- vuam. Qhov no weldability tso cai rau seamless koom nrog ntawm cov khoom, txo kev cia siab rau cov neeg kho tshuab fasteners thiab tsim kom muaj kev ruaj khov, streamlined designs.

5. Hnav & Abrasion Resistance

Cov hlau alloy's microstructural muaj pes tsawg leeg- sib txuas zinc lub toughness nrog txhuas lub hardness- muab kev hnav zoo heev.
