HF 1000: Crushed Tungsten Carbides are fused together within a tough polycrystalline matrix of nickel. The 3mm grain size ensures greater concentration of carbide which is ideal for soft formation drilling.
HF 2000: Geothermal Dressing: trapezoidal tungsten carbide inserts are held in a sintered carbide nickel bronze matrix. This will give a greater depth of carbide coverage – ideal for high deviation drilling in abrasive formations.
HF 3000: Metal Powder spray is used to fuse the tungsten carbides. This spray deposit is ideal for abrasive formations. Recommended for non-magnetic stabilizers
HF 5000: Flexicoy Technodur: Fused tungsten carbide in a nickel chrome boron matrix designed for oxy-acetylene torch application. Flexicoy has pure nickel core surrounded by fused tungsten carbide and alloy elements for the matrix.
HF 6000: Flexicoy Technosphere & Diamond Tungsten Carbide Inserts: Diamond inserts and tungsten carbide inserts are set in a powder spray deposit – ideal for very abrasive formations.
