Customized Black Zirconia Ceramic Wearable Samrt Ring



Alumina Ceramic Ring is the best-known advanced ceramic material, is widely used in automotive, petro-chemical,fluidcontrol,materialtransfer,Industry,electrical and electronic,semiconductor.Sapphire is single-crystal alumina.
 
Mingrui Ceramic is making high quality ceramic products.
Alumina ring is our main product. It`s mainly made by 95% and 99.7% Al2O3. Density from 3.6g/cm3 to 3.9g/cm3 .
We have the ability to machine the alumina ring, Tolerance can reach to +/-0.02mm after machining. Surface roughness can reach to Ra0.2um. Holes and grooves can be machined as you need.
Very big sized and small sized rings can be made according to your need.
