Specification of solid carbide rods and material grades

When ordering CF Tungsten solid carbide blanks, start with the specific alloy grade and geometry. The factory offers grades CF10, CF12, CF6UF and CF8UF for cutting tools, differing in cobalt content, WC grain size, hardness (HRA) and transverse rupture strength (TRS).

Specify outside diameter, overall length and surface condition for solid rods. Standard stock is available in 310 mm and 330 mm lengths as sintered unground blanks with machining stock, or centerless ground to ISO h6 tolerance. Ground finish ensures minimal radial runout in CNC collets.

For tool replacement or custom shank manufacture, provide the target workpiece material and cutting parameters. Submicron grades CF6UF and CF8UF provide optimal edge stability when machining hardened die steels, titanium alloys and high-temperature nickel superalloys.

Internal coolant hole rods for deep hole drilling

For tools requiring internal coolant supply, CF Tungsten produces cemented carbide rods with through-coolant holes. Configurations include single central straight hole, two parallel straight holes, and two helical holes for twist drill fluting.

When ordering helical coolant rods such as series CF710, CF510 or CF512, specify the helix angle (standard 30° or 40°). In addition to outside diameter and length, define coolant hole diameter and pitch circle diameter (PCD).

Factory inspection guarantees hole concentricity and constant helical pitch across the entire 330 mm length. Stable helix pitch prevents wall penetration during flute grinding on multi-axis CNC tool grinders for 3xD, 5xD and 8xD drills.

Tungsten carbide and pure metallic powders

Tungsten monocarbide (WC) and metallic tungsten (W) powders form the foundation of hardmetal production. The primary classification metric is Fisher sub-sieve size (FSSS), alongside laser diffraction particle size distribution. Grades FWC-1 and FWC-2 cover 0.6–0.8 μm to over 15 μm.

In powder specifications, chemical purity is vital. Quality metrics include total carbon, free carbon, oxygen content and trace metal impurities (Fe, Ni, Si, Ca). Controlled free carbon prevents graphite inclusions or brittle eta-phase Co3W3C formation during sintering.

For metallic tungsten powders FW-1 and FW-2, bulk density and BET specific surface area determine compressibility. Crystalline tungsten powder and tungsten granules are also supplied for combustion carbon and sulphur infrared analysers.

Cast tungsten carbide for hardfacing and wear parts

Cast tungsten carbide (CWC) is an eutectic mixture of WC and W2C with a fine needle-like microstructure. Produced by high-temperature arc melting and crushing or atomization, it provides outstanding abrasive wear resistance for components working in soil, ore and slurry.

CF Tungsten produces CWC powder in multiple mesh fractions, including CWC5-10, CWC20-30, CWC40-60 and CWC80-200. Sizing depends on the cladding process: plasma transferred arc (PTA), laser cladding, oxy-acetylene welding or flexible wear rope manufacture.

When ordering CWC materials, specify the matrix alloy (nickel, cobalt or iron base), working temperature and deposit thickness. Coarse particles provide barrier protection against heavy gouging, while fine fractions disperse evenly in the braze matrix.

Carbide wear strips, plates and rotary burr blanks

Rectangular cemented carbide strips of the LF series serve in woodworking planer knives, paper and polymer slitting blades, and machine tool guide rails. Standard grades LF08, LF10 and LF30 provide balanced toughness and wear resistance.

For stamping dies and punch tooling, submicron grades LF06F, LF08F and LF10F are recommended. The fine carbide matrix resists micro-chipping under cyclic impact against stainless or spring steels. Specify dimensions, grinding stock and edge finish requirements.

In the burr blanks segment, the plant supplies heads across shapes A through M (cylindrical, ball-nosed, flame, oval, conical) for tool brazing. State head shape, diameter, cutting length and shank hole bore diameter.

Tungsten chemical compounds for catalysts and synthesis

The chemical division of Ganzhou CF Tungsten converts ore concentrates into high-purity salts and oxides. Ammonium paratungstate APT-0 serves as the primary crystal precursor for calcination into tungsten trioxide and subsequent hydrogen reduction.

Ammonium metatungstate AMT-90 and AMT-91 features extreme water solubility exceeding 1000 g/l at room temperature. It acts as an essential precursor for hydrotreating and desulfurization catalysts in petrochemical refining, requiring minimal sodium, potassium and sulphur content.

Sodium tungstate dihydrate serves in fire retardants, pigments and metal etching, while pure tungstic acid is utilized in fine synthesis. Yellow and blue tungsten oxides (YTO and BTO) are manufactured for optical glass, piezoceramics and fine carbide powders.
