It is perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools, polishing and sandblasting grit.


2. Attribute

SiO2 Max 1.4%
Grain 300-250um
Feature Low linear expansion coefficient
Application Burnishing


3. Advantages

1. High density so that is less dust in the process of sandblasting

2. Be reused several times and high efficiency

3. Increased brand recognition and competitive pricing

4. Raw manufacturers can transfer their processes to meet special needs


4. Applications

    Brown corundum, under a certain pressure, can quickly impact the surface of the object with a large number of sharp edges, so it is regarded as a very fast spray grinding method.


    It is suitable for the production of ceramic, high-resistance abrasive resin and grinding, polishing, sandblasting, precision casting, etc., it can also be used to manufacture high-grade refractories.
