Polycrystalline Al2O3 alumina ceramics customized kub hnav tsis kam

Lus piav qhia luv luv:

Alumina ceramics (Al203) yog ib qho hnav-tiv taus precision ceramic khoom uas yog dav siv nyob rau hauv ntau yam lag luam. Lub ntsiab molding txoj kev rau alumina ceramic khoom yog qhuav nias, isostatic nias, txhaj tshuaj molding thiab casting, thiab lwm yam. Cov khoom sib txawv, qhov ntau thiab tsawg thiab precision yuav tsum tau sib txawv molding txoj kev. Tom qab kub kub sintering ntawm alumina ceramic khoom, tsuas yog siv cov pob zeb diamond sib tsoo txheej txheem tuaj yeem ua tiav. Lub purity ntawm ntau alumina ceramics yog 90% -99.9%.

Kev ua haujlwm ntawm aluminium oxide ceramics

1 - Hardness siab

Rockwell hardness ntawm alumina ceramics yog HRA80-90, thib ob tsuas yog pob zeb diamond hauv hardness, deb tshaj li hnav-resistant steel thiab stainless hlau hnav tsis kam.

2-- Kev hnav tsis zoo

Kev hnav tsis kam ntawm alumina ceramics yog sib npaug rau 266 npaug ntawm manganese hlau thiab 171.5 npaug ntawm cov chromium cam khwb cia hlau. Raws li tib yam kev ua haujlwm, nws tuaj yeem txuas ntxiv lub neej kev pabcuam ntawm cov khoom siv tsawg kawg kaum zaug.

3-- Lub teeb nyhav

Qhov ceev ntawm alumina ceramics yog 3.7 ~ 3.95g / cm °, uas tsuas yog ib nrab ntawm cov hlau thiab hlau, thiab tuaj yeem txo cov khoom siv ntau heev.

4--Kev siv ntau yam

Alumina ceramics tau dav siv hauv tshuab, fiber ntau optics, txiav cov cuab yeej, kho mob, zaub mov, tshuaj, aerospace thiab lwm yam.

Qhov zoo ntawm alumina ceramics:

1-Alumina ceramics muaj cov khoom zoo heev insulating. High-frequency poob yog me me, thiab high-frequency rwb thaiv tsev yog zoo.

2-Alumina ceramics muaj cov cua sov ua haujlwm, me me coefficient ntawm thermal expansion, siab txhua yam muaj zog thiab zoo thermal conductivity.

3-Alumina ceramics muaj tshuaj tiv thaiv thiab molten hlau tsis kam.

4--Alumina ceramics tsis yog nplaim taws, tsis yooj yim rau xeb thiab muaj zog thiab tsis yooj yim rau kev puas tsuaj, nrog rau lwm cov ntaub ntawv organic thiab cov ntaub ntawv hlau tsis tuaj yeem muab piv nrog cov khoom zoo heev.

5-Alumina ceramics superior hnav tsis kam, hardness thiab corundum tib yam, tuaj yeem ncav cuag Mohs hardness 9, nws hnav tsis kam tuaj yeem sib phim nrog super-hard alloys.
