MACROLINE TUNGSTEN CARBIDE combines the advantages of Cast Tungsten Carbide (CTC) with those of mono tungsten carbide (WC). Each of the irregularily shaped MTC particles consists of a high hardness CTC core and a shell of WC, preventing formation of brittle eta phases during welding. Carbon content of MTC is in the range of 4.3 to 5.2 wt.-%. Hardness values are in the same range as CTC.
Blends of MTC with Ni, Fe or Co based alloy powders are used to produce superior wear and shock resistant coatings by PTA welding, lasercladding or other wear protective welding applications. Furthermore, MTC can be used for the production of drill bits by infiltration.
