White Fused Alumina Blasting Media

White fused alumina blasting media is a non-metallic reusable blasting media based on high-purity alu­minum oxide (Al₂O₃). It meets the requi­re­ments of DIN EN ISO 11126–7 N/FA-WA/G as well as the occu­pa­tional safety spe­ci­fi­ca­tions of DGUV Rule 100–500, Chapter 2.24 “Working with blasting equipment (blasting work)”. 

White fused alumina is pro­duced by melting alumina in an electric arc furnace and belongs to the group of electro-cor­undums. With a Mohs hardness of 9, it is one of the hardest known blasting media – only diamond is harder. 

Due to its sharp edges, purity, and lack of iron, white fused alumina is the ideal blasting media for appli­ca­tions with the highest requi­re­ments for surface quality, pre­cision, and purity.

White fused alumina blasting media is sui­table for cleaning, deburring, matting, and struc­turing various sur­faces. Thanks to its hardness and che­mical purity, it gua­rantees high effi­ciency and con­sistent surface quality – even with repeated use. White fused alumina is the first choice in indus­tries where absolute surface purity is crucial.

The grain size of the blasting media deter­mines the surface structure and material removal. Fine grains produce smooth, matte sur­faces, while coarse grains allow for intensive cleaning and roughening. 

Tip: For stainless steel and alu­minum, finer grains are ideal for achieving smooth, clean sur­faces. For heavier removal or thermal coa­tings, coarser grains are recommended. 

Cor­undum pro­ducts are available in both metric and FEPA grain sizes. See data sheet.
