CF Tungsten

SpareX handles sourcing enquiries for CF Tungsten powders, chemical compounds and cemented-carbide blanks from China. The range serves toolmaking, powder metallurgy, laboratories, chemical processing and steelmaking. Manufacturer: Ganzhou CF Tungsten Co., Ltd. Explore 18 product families with applications and enquiry parameters.

Powders and granules: production feedstock

Tungsten carbide powder WC — FWC-1: WC ≥99.8%; FWC-2: ≥99.7%. For cemented-carbide cutting tools, mining tools and wear parts. Listed FSSS classes range from 0.6–0.8 to over 15 μm. Specify grade, particle size and oxygen/carbon limits.

Tungsten metal powder W — FW-1: W ≥99.95%; FW-2: ≥99.9%. Feedstock for tungsten products, alloys and WC powder. FW-2 also covers contact alloys and high-density materials. Select by purity, FSSS size and bulk density.

Cast tungsten carbide — CWC-1 and CWC-2 combine WC and W₂C for wear protection and tooling. Size designations include CWC5-10, CWC20-30, CWC40-60 and CWC80-200. Specify mesh fraction and the intended coating or part-making process.

Crystalline tungsten powder — Listed separately as Crystalline Tungsten Powder. Send the required particle-size distribution, purity and impurity limits for process matching. Any substitution with another tungsten powder requires specification review.

Tungsten granules — W ≥99.9%; fractions 10–20, 20–40, 40–60, 60–100 and 100–200 mesh. Used as a flux in medium- and high-frequency combustion analysis. Laboratory enquiries should specify mesh size and carbon/sulphur background limits.

Molybdenum powder — FMo-0: Mo ≥99.95%; FMo-1: ≥99.9%. The company catalogue lists FSSS 2–4 μm. Specify grade, oxygen and other impurity limits, quantity and the intended material application.

Cemented carbides: toolmaking blanks

Solid cemented-carbide rods — Blanks for end mills, drills and reamers: CF10, CF12, CF6UF and CF8UF. Diameters 2–50 mm; unground and H6-ground versions. CF6UF is listed for microtools and composite machining; final selection depends on the workpiece and operation.

Rods with coolant holes — CF710, CF510 and CF512; one straight hole, two straight holes or two helical holes. For tools with internal coolant delivery. The main specification lists diameter 3–26 mm and length 330 mm. Provide a hole drawing, dimensions and tolerance.

Cemented-carbide strips and plates — Listed grades: LF08, LF10, LF30, LF06F, LF08F and LF10F. WC with a cobalt binder. Provide length, width, thickness, grade and surface-finish requirements; blank dimensions are checked against the drawing.

Carbide burrs and burr blanks — The range includes Tungsten Carbide Burrs / Burr Blanks. Distinguish a finished rotary burr from a blank for tool manufacture. Specify head shape and dimensions, shank details, quantity and required manufacturing state.

Tungsten compounds: chemical feedstock

Ammonium paratungstate APT — APT-0: WO₃ ≥88.5%; FSSS 35–46 μm. An intermediate for tungsten oxides and sodium tungstate. State grade, impurity limits and required particle size.

Ammonium metatungstate AMT — AMT-90 and AMT-91: WO₃ minimum 90% and 91%. Listed uses include petrochemical desulphurisation and tungsten materials. Specify composition, your solubility requirements and the process specification.

Sodium tungstate dihydrate — WO₃ content ≥68%. A water-soluble tungsten salt. Supply enquiries should state the main-component specification, impurity limits and packaging. WO₃ content must not be confused with elemental tungsten content.

Tungstic acid — Chemical feedstock for catalytic processes, reagents, pigments and tungsten compounds. Match the application and allowable impurities to the particular process; attach your technical specification.

Tungsten oxides YTO and BTO — Yellow oxide: YTO-0, YTO-1; blue oxide: BTO-0, BTO-1. Applications include W/WC powder production, electronics and ceramic pigments. These are different oxide materials: specify composition, oxide type and particle size.

Metals and ferroalloys

Ferro tungsten — FeW80-A, FeW80-B and FeW80-C: W 75–85%; listed lump size 5–100 mm. An alloying addition for steelmaking. Grades differ in impurity limits; specify the full grade and melt requirements.

Tungsten bars and plates — W-1 and W-2: W ≥99.95%; W-4: ≥99.90%. Listed uses: W-1 for tungsten alloys, W-2 for processing stock, W-4 for alloying. Specify dimensions, density, grade and application.

Molybdenum bars and plates — Listed in the official catalogue under steelmaking materials. Shape, dimensions, Mo content and impurity limits are confirmed for the enquiry. A finished component requires its own drawing rather than a raw-stock specification.

Match the material to the job

For drills and end mills, start with carbide rods and define workpiece material, operation, diameter, length and coolant channels. For cemented-carbide sintering, specify WC powder size distribution and chemistry. For wear protection, check cast carbide against your process. Chemical applications need a defined compound and composition; steel alloying needs the ferroalloy grade and impurity limits.

Request supply through SpareX

Send the material name or grade, quantity in kilograms or pieces and intended use. For powders, add FSSS or mesh fraction, purity and impurity limits. For blanks, attach dimensions, tolerances, surface condition and a drawing. If the grade is unknown, provide the specification of your existing material. Product match, supply feasibility, price, lead time and documents are checked for each enquiry and agreed before ordering.
