WC/CrNi, WC/NiCr - SURPREX W2000X


The SURPREX W2000X series of thermal spray materials are agglomerated and sintered composite powders whcih consist of Tungsten Carbide (WC), Chromium (Cr), and Nickel (Ni). Both excellent toughness and greatly improved impact resistance are achieved in sprayed coatings of W2000X, with wear resistance equal or superior to conventional WC cermet coatings. These revolutionary spray materials provide coatings to simultaneously achieve all three quality requirements of wear, corrosion, and impact.

Three types of particle sizes of SURPREX W2000X are available, suitable for different spray guns.
