Difference of garnet powder and brown corundum powder
It is confirmed that there are some differences between brown corundum micropowder and garnet micropowder,now explain and list them:
First: raw material
Brown corundum is made from bauxite,but garnet is natural from garnet mine.
Secondly: appearance
Brown corundum powder looks more blackish,but garnet powder redish.
Third:Classification media
Brown corundum powder is classificated by water,but garnet powder is by airflow.
Fourth:Main chemical compostion
Brown corundum :Al2O3,but garnet powder is SiO2.
Fifth:Hardness
Brown corundum has higher mohs hardness,which is about 9.0,but garnet is about 7.5-8.0.so brown corundum powder is used for blasting,grinding and polishing harder parts,but garnet powder is a little soft comparatively,then it can be chosen to be used for soft workpieces.
Sixth:Cost
Brown corundum is artificial abrasives,its process is very complex,so it cost higher,but garnet powder is from natural garnet,cost lower,if the user take cost into consideration too much,garnet powder is a better choice.
Seventh:Environment protection
When blasting/grinding/polishing,brown corundum powder will produce more dust.
In summary,both brown corundum powder and garnet powder has their own properties and advantage,and are very important in their own stage.
