Infiltration (Matrix) Powder
Infiltrating (matrix) powders mainly consist of fusible metal and one or more kind of powders of casting tungsten carbide, macro-crystalline tungsten carbide,tungsten carbide.By changing composition, particle size of hard phase,bonding metal composition and sintering process depend on the ground conditions and working condition requirements,we can get matrix components with different hardness and wear resistance which mainly used for surface mount and the carcass drill manufacturing (PDC drill bits) of oil exploration or mining, and other components of infiltration.
