Blue zirconia ceramic guide pin Material introduction:

Zirconia ceramics is a new type of high-tech ceramics. It has excellent characteristics such as high strength, high hardness, high temperature resistance, acid and alkali corrosion resistance. It is an insulator at room temperature and has conductivity at high temperature.

The melting point of zirconia is 2715 ℃, the higher melting point and chemical inertia make zirconia a a better refractory.

Zirconia ceramics have high hardness and good wear resistance. The Mohs hardness of zirconia ceramics is about 8.5, which is very close to that of sapphire 9, that of tempered glass is 5.5, that of aluminum magnesium alloy is 6.0, and that of Corning Glass is 7.

Zirconia ceramics have great strength. Although there is a big gap between toughness and some metals, it is better than other ceramic materials.

The thermal conductivity of zirconia is the lowest among common ceramic materials, and the coefficient of thermal expansion is close to that of metal. Therefore, zirconia ceramics are suitable for structural ceramics.

Zirconia ceramic guide pin  is widely used in welding machines. Because zirconia ceramics have the advantages of high toughness, high bending strength, high wear resistance and excellent thermal insulation, zirconia ceramic positioning pin  is not easy to wear and break in the process of use, and its service life is longer.

We can provide zirconia ceramic guide pin of various colors for you to choose (white zirconia, blue zirconia, etc.). According to the needs of customers and different types of welding machines, ceramic guide pin with different appearance models can be customized and developed to adapt to various models to meet the needs   of different welding machine .
