Due to its high hardness (around HV1400), zirconia ceramic materials for smartwatches have certain requirements for the processing and polishing of raw materials. Our company adheres to the excellent technology of processing sapphires with higher hardness and has formed a quality system specifically for processing and polishing zirconia, which has the characteristics of high yield, good accuracy, and high degree of automation.

In addition, due to the company's existing sapphire quality system, we have strict requirements for the appearance quality of zirconia, and our current comprehensive evaluation has considerable advantages.

Basic characteristics of zirconia ceramics:

① High hardness, Vickers hardness of 1300-1400, wear-resistant, scratch resistant;

② Dielectric constant of 26-35, more sensitive to signals and data;

③ There are various molding methods, and the production capacity can be rapidly expanded;

④ Low human rejection, good skin affinity, can be worn or implanted close to the body;

⑤ Among materials of the same hardness, they have higher fracture toughness and bending strength;

⑥ The available colors are quite diverse;

⑦ Good insulation and electrical isolation, suitable for wireless charging.

Advantages of zirconia ceramic materials:

Enhance durability: The high hardness ceramic case can effectively resist scratches and impacts during daily use;

Enhanced comfort: The warm touch of ceramics makes long-term wearing more comfortable;

Beautiful and elegant: The luster and texture of ceramics add a high-end and elegant appearance to smartwatches.
