Character of Microcrystal Wear Alumina Ball(CIP)
Using foreign imports, the original grain size less than 1 micron alumina, calcined with high-temperature tunnel kiln, the grain size controlled growth to more wear coefficient at the end. Coupled with advanced roller-made technology and equipment, not only ensured the whole round appearance, size specifications rich, but also guarantied the stability and reliability of the product quality
Notes:We can pack the products according to your requirement,also we can do OEM or ODM.
