Aluminium yog lub teeb thiab ncaj cov hlau uas muaj lub matte nyiaj xim. Tsis tas li ntawd, nws yog fusible heev, uas yog vim li cas ntau ntawm alloys yog tsim los ntawm nws.
Cov Lus Qhia
Kauj ruam 1
Aluminium yog tshuaj lom neeg ntawm lub pab pawg thib peb ntawm lub rooj ntu ntawm cov khoom siv tshuaj. Nws muaj cov txheej txheem tshuaj lom neeg muaj zog thiab cov yas siab. Aluminium yog suav nrog cov khoom siv ntau ntawm cov ntxhia thiab pob zeb. Vim nws cov khoom yas, ntau ntawm cov hlau thiab cov qib tau tsim los ntawm cov hlau no.

Txhua qib ntawm txhuas muaj qhov tsis suav nrog tus lej lossis cov qauv siv tshuaj, uas muaj lub cim "kev xaiv ntawm alloy". Muaj cov txheej txheem thoob ntiaj teb thiab lub teb chaws raws li uas txhuas tau koom nrog ua ib pawg sib cais 1xxx (lossis 1000). Cov txheej txheem European EN755 kuj tseem siv tau rau nws, raws li cov hlau thaum xub thawj suav tias yog ib qho txhuas, thiab raug xaiv raws li "aluminium alloy 1050A".

Hauv peb lub tebchaws, thaum lub sijhawm, cov qauv ntawm GOST 4784-97 "Aluminium thiab wrought allolo alloys" muaj nyob rau hauv kev sib zog. Raws li cov qauv no, lo lus "hom" tsuas yog siv rau aluminium, thiab alloys alloys tseem nyob nrog lub npe no.

Txhua xyoo nyob rau hauv kev lag luam, ntau cov txhuas alloys tau tsim, thiab txhua tus ntawm lawv muaj nws tus kheej GOSTs.
Yog li, GOST 11069-2001 tswj kev tsim cov khoom siv hluav taws xob theem pib ua ib daim ntawv ntawm txoj hlua, ingots thiab kua xeev. Nws tsim qib ntawm txhuas los ntawm nws cov feem pua hauv cov feem ntau. Lub purest yog suav hais tias yog txhuas qeb A999. Nws muaj tsawg kawg yog 99.999% hlau. Muaj cov hom nram qab no: A995, A99, A85, A8, A7, A6, A5 thiab A0.

Raws li GOST 4784-97, thawj thiab theem pib aluminium yog qhov txawv, uas yog tus yam ntxwv ntawm cov npe AD000, AD00, AD0, AD1 thiab AD. Tus neeg thib ob feem ntau yog hu ua kev vim nws muaj qhov ntau ntawm qhov tsis txaus. Nws yog tsim nyob rau hauv hom ntawm AD00E, AD0E, ADch, ADoch. Los ntawm nws cov tshuaj lom neeg cov kev ua, aluminium tuaj yeem sib txawv rau deoxidation. Nws sib raug rau cov hom xws li AV86, AV86F, AV88, AV88F, AV91, AV91F, AV92, AV92F.

Ntxiv nrog rau txhuas yooj yim, nws cov alloys feem ntau siv. Cov tebchaw no tsuas yog siv tshwj rau thaum kub lossis qis heev. Alloys lub ntsiab yog suav tias yog alloys ntawm qib: 1100, 2014-T6, 2024, 2090, 2219, 3003, 5083. Raws li txoj cai, lawv tau cais los ntawm lub zog loj thiab cov thermal tsis kam.
Qee qhov pib ntawm qhov yooj yim yog wrought aluminium alloy thiab aluminium antifriction alloy. Raws li, lawv muaj hom 1201, 1420, AD31, AD33, AD35 thiab AMST, AN-2, 5, AO20-1, AO9-2B.
