Product Detail

Khoom cim npe

Alumina ceramics

1. Siab hardness

Rockwell hardness yog HRA80-90, qhov hardness yog qis dua pob zeb diamond, deb tshaj qhov hnav-resistant steel thiab stainless hlau.

2. Kev hnav zoo heev

Ntsuas los ntawm cov chaw tshawb fawb kev tshaj lij, nws qhov hnav tsis kam yog sib npaug rau 266 npaug ntawm manganese hlau.Gaoming cam khwb cia hlau 171.5 zaug, raws li peb ntau tshaj kaum xyoo ntawm kev soj ntsuam cov neeg siv khoom, nyob rau hauv tib txoj kev ua haujlwm, tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm cov khoom siv tsawg kawg kaum zaug ntxiv.

3. Lub teeb yuag

Nws qhov ceev ntawm 3.5g / cm3 tsuas yog ib nrab ntawm cov hlau, uas tuaj yeem txo cov khoom siv thauj khoom.

Nta:

Siab mechanical zog

High resistivity thiab zoo rwb thaiv tsev

Mohs hardness ntawm 9 thiab zoo heev hnav tsis kam

High melting ntsiab lus thiab corrosion kuj

Zoo skev ruaj ntseg

Optical zog
