50/50 Tungsten Carbide / Nickel Chromium Silicon Boron Hardfacing Alloy
CT3302-4 is a Nickel Chromium Silicon Boron/ Tungsten Carbide material which, when sprayed with HVOF technology and then fused creates a very wear resistant layer. This layer exhibits better wear resistance in many applications than would be typical even of another fused coating with the same percentage of tungsten carbide due to the fine particle size of the carbide. In addition to the very high wear resistance, the coating also shows high impact resistance.

For the Following Applications:
CT-3302-4 is used for high wear applications such as wire drawing capstans, pump sleeves, pump impellers, mechanical seal faces, feed screws, extruder screws, ball valves and hammer mill components.
Finish this coating by grinding with diamond wheels or lapping with diamond paste. Typical wheel recommendation is a 100 mesh nickel clad diamond in a resin bonded matrix. Large surfaces may require a softer wheel. Coolant must be flooded onto part and wheel during grinding.
Recommended lapping parameters:
CT3302-4 meets the following specifications:
