Alumina Ceramic Ring is the best-known advanced ceramic material, is widely used in automotive, petro-chemical, fluid control,materialtransfer,Industry,electrical and electronic,semiconductor.Sapphire is single-crystal alumina.
Mission 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.
Warranty:
If any broken during shipment, we will send replacement for free or send back your payment. (In case we arrange the shipping).
If tolerance is not same with what we discussed, we will send replacements.
