1. Lub siab hardness ntawm alumina ceramics tau txiav txim los ntawm Shanghai lub koom haum ntawm Ceramics, Suav Academy ntawm Sciences, thiab nws Rockwell hardness yog HRA80-90, thib ob tsuas yog pob zeb diamond, thiab hnav tsis kam yog ntau tshaj li ntawm hnav-resistant steel thiab stainless hlau.
2. Alumina ceramic muaj kev hnav zoo heev, nws hnav tsis kam yog sib npaug rau 266 npaug ntawm manganese hlau, 171.5 npaug ntawm cov chromium cam khwb cia hlau siab. Raws li kev soj ntsuam kev soj ntsuam ntawm peb cov neeg siv khoom rau ntau tshaj kaum xyoo, nyob rau hauv tib lub sijhawm ua haujlwm, kev pabcuam lub neej ntawm cov khoom siv ceramic tuaj yeem txuas ntxiv los ntawm tsawg kawg kaum zaug.
3. Alumina ceramics lub teeb yuag alumina hluav taws xob ceramics ntom ntawm 3.5g / cm3, tsuas yog ib nrab ntawm cov hlau, tuaj yeem txo cov khoom siv zoo heev.
