Description

Zirconia Drawing Machine Tower Round , Wire Wheels , Reel.

1. Description:

The technical properties of silicon carbide are remarkably similar to those of diamond. It is one of the lightest, hardest, and strongest technical ceramic materials and has exceptional thermal conductivity, chemical resistance, and low thermal expansion.Silicon carbide is an excellent material to use when physical wear is an important consideration, because it provides good erosion and abrasive resistance, making it particularly suitable for such applications as spray nozzles, shot blast nozzles, and cyclone components.Not so long ago, silicon carbide was the chosen material to line the brakes of the most advanced, jaw-dropping cars the world has ever seen; the McLaren P1 for example.

2. Feature Advantages:

1) High density.

2) High fracture toughness .

3) High hardness High Mechanical Strength.

4) Low thermal conductivity Excellent insulation .

5) Good Wear resistance.

6) Resistant to Corrosion and Chemical Attack.

7) Extreme Temperature Stability.

8) Outstanding Electrical and Electronic Properties.
