Aluminium oxide should be a soft material, how can be it used as a cutter?

Kasturi said:   1 decade ago
Aluminium oxide is used for its hardness and strength and low specific heat.

Seenu said:   1 decade ago
Yes its one of the main property of aluminum mixer.

Sandhiya said:   1 decade ago
Aluminium oxide is have a high temperature.

Rumela said:   1 decade ago
Silicon carbide has a greater impact-resistance than aluminium oxide. Then why can't we use SiC?

Swap said:   1 decade ago
Aluminium oxide is resistance to corrosion and its a hard metal too.

Then whats the concept behind using silicon coating in turbine blades?

Kenneth said:   1 decade ago
Silicon carbide or aluminum oxide are both used. But, when cost and readily available material is needed Aluminium oxide is used.
