Ceramic Smart Bracelet


Smart wearable bracelet is widely used in smart wearable devices due to the use of zirconia, alumina and other advanced ceramic materials, with good skin affinity, cleanness, wear resistance and other characteristics.

Smart wearable bracelet, high hardness, no rust color, no contamination, stable chemical performance advantages make ceramic materials become the latest must-haves in the jewelry industry, the use of high-tech ceramic composite materials manufacturing ceramic intelligent wear bracelet, with corrosion resistant and heat resistant performance is good, high hardness, not easy to wear and tear, never fade, the advantages of not damage the skin.
 
Advantages of Smart wearable bracelet over steel:
1 hard as jade, not afraid of scratches, wear, will not lose luster.
2. The surface can also be crystal clear, smooth and shiny with fine grinding;And the traditional material such as stainless steel is no matter how the processing is impossible to present a pure black and pure white.
3. Material such as jade does not hurt the skin and feels smooth and comfortable.
4. Not afraid of water drenching, not afraid of sweat stains, not afraid of corrosion, never rust.
5. Ceramic ring is a new favorite of jewelry industry. It has a high scientific and technological content and can reflect the scientific and technological fashion of the new era.
