Ceramic materials and steel basic performance comparison

Compared with the steel balls, zirconia balls main advantages:

1, 23% lighter than steel balls, reducing the bearing running speed and acceleration on the channel centrifugal force, crush and abrasion;

2, the friction coefficient is small, rotation can be good flexibility;

3, high temperature, temperature can reach 750 ℃;

4, never rust, no oil lubrication in working conditions;

5, more chemical resistant than steel;

6, no metal contamination;

7, the non-magnetic;

8, the electrical insulation.

Purpose:

Zirconia ceramic ball valve is mainly used for the ball, full ceramic bearings, measuring ball, trackball, fine grinding balls can be used for high-temperature resistance, corrosion resistance, insulation, absolutely magnetic, non-lubricated and other occasions, is corrosive occasions substitute balls ideal material...

As the valve ball use, zirconia ceramic ball has been successfully used in high-pressure homogenizer, diaphragm pumps, metering pumps, oil pump, high-pressure spray gun and other equipment.

Product Features: density of 6.05g/cm3.

Specifications: 0.4mm ~ 50.8mm (1/64 "~ 2")

Available grade: G5 ~ G40.

Note: 1) white zirconia balls based, if necessary, can also provide a yellow zirconia balls.

2) has a large inventory to meet delivery requirements at any time.

3) non-standard sizes to meet the requirements.

4) The thermal expansion coefficient of zirconia 10.5 ×10^-6 / ℃, the thermal expansion coefficient close to the metal, and metal with good stability with temperature changes but the size is large, a contact failure in the form of rolling fatigue destructive fragmentation, in some critical situations as silicon nitride material stability.
