Abrasive Blast Nozzles

SiC and B4C Nozzles

Nozzles are available in three materials:

Hexoloy^® SA silicon carbide
Norbide^® boron carbide
Silit^®SKG SiSiC Silicon Carbide

All three materials have exceptional intrinsic hardness which enables superior wear and abrasion resistance to a wide range of abrasive solid and liquid media. 

In addition, boron carbide is more lightweight versus all other nozzle options.
