WC/10%Co/4%Cr - SURPREX W1004

The SURPREX W1004 series of thermal spray powder materials are based on Tungsten Carbide, Cobalt, and Chromium compounds. The particle size and strength are strictly controlled during agglomerating and sintering processes to avoid spitting during spraying. Excellent corrosion resistance is exhibited in both dry and wet environments with a great deal of improvements made on poor corrosion resistant WC/Co-type cermets. Well-balanced spray coatings are produced by a combination of high hardness, wear resistance, and toughness.

Four types of SURPREX W1004 and numerous development products are available, suitable for different spray guns.
