High temperature and abrasive resistance is good
Product features :
Applicable to make ceramic wrist watch, watch ctrap, bracelet, ring and necklace etc. With the property of abrasion resistance, invariant color, elegance and shining, ceramics are the ideal decorative material for watch and jewelry industry. All the ceramics can be customized.
1. High hardness.
2. High heat resistance : Alumina ceramic has excellent thermal stability,which means that it is
widely used in areas where resistance to high temperatures is essential.
3. Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.
4. High electrical resistivity : Alumina is an electrically insulating material.
5. High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and
alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.
