Cov txhuas alloy 2024 raj

{1. Cov qib Astm ntawm Aluminium Alloy 2024 raj?

ASTM B211 / B211M: Cov qauv no npog txhuas thiab aluminoy-aluminoy tsho extruded tuav, cov pas nrig, thiab cov raj kub, e {} g.,T3, T351, T4, T6) tau teev raws li cov khoom siv uas xav tau thiab ua cov haujlwm ua .

Cov sam thiaj sib xws:

T3: Tshuaj kub kho, ua haujlwm txias, thiab ib txwm muaj hnub nyoog.

T4: Tshuaj kub-kho kom sov thiab ib txwm muaj hnub nyoog .

T6: Tshuaj kub-kho kom sov thiab muaj zog (muaj lub zog siab dua tab sis txo tus qauv sib dhos thiab txo qis dua li t3 / t4).

2. Cov cuab yeej siv cov khoom siv tau zoo li cas ntawm txhuas alloy 2024 raj?

Ntiag tug	Tus nqi

4. Yuav ua li cas yog daim ntawv thov ntawm aluminium alloy 2024 raj?

Ib tug tub rog: Cov qauv dav hlau tsim (e {. g}}, fingselage thav duab, rivets, thiab fitings.

Pab tub rog: Cov cuab yeej sib xyaw ua plating, cov chaw ua haujlwm tsis tu ncua, thiab cov khoom siv tub rog muaj kev nyuaj siab.

Automotive: Kev sib tw tsheb tsheb, tsav cov phuam, thiab kev ua haujlwm siab.

Cov Khoom Siv Ua Si: Cov thav duab tsheb kauj vab, cov chaw ntaus pob golf, thiab ntaus pob tesniv pob tesniv thav duab .

Tus sawv cev ua tub rog: Cov pa hluav taws xob muaj zog zog (nrog kev tiv thaiv xeb kom zoo) .

5. Dab tsi yog qhov zoo ntawm txhuas alloy 2024 raj?

Siab zog-rau-qhov hnyav piv: Qhov zoo tagnrho rau qhov hnyav-tseem ceeb (e . g., aerospace).

Foob zoo heev: Withstands cyclic thau khoom, ua rau nws haum rau kev siv cov qauv zoo .

Lub tshuab zoo: Tuaj yeem yog machined kom nruj rau kev zam, txawm tias nws yuav tsum tau cov cuab yeej ntse thiab kom qhuav txias .

Thaum Tshav Kub Kub Kho: Lub zog tuaj yeem txhim kho los ntawm kev kho cua sov (e {{{} g}}, t6) {{4 4}}

Hwj txwv: Vuam yog ua tau tab sis txo lub zog nyob rau hauv lub tshav kub-cuam tshuam rau hauv cov ntawv thov tseem ceeb).

Kev txwv:

Corrosion Kuj: Qis dua alloys zoo li 6061 lossis {{{1} Yuav tsum muaj cov tshuaj pleev xim rau (E {}

Muaj meej: Tsawg dua tsim tau ntau dua li tsis-ua cua sov-alloys (e .}} {.
